AB  - Planiranje nacionalnog energetskog sistema preko sagledavanja alternativnih investicionih odluka kroz godišnje simulacije (korišćenjem alata EnergyPlan) zbog svoje (kombinatorne) složenosti ostavlja malo prostora za eksplicitnost u pogledu uticaja mreže na planerske odluke i zato postoji potreba da se sagledaju i tokovi snaga u mreži. Investicione odluke koje se donose ostaju sa dozom nedorečenosti u tehničkom pogledu, koja se ovom spregom može otkloniti. Alat CASE se koristi za brojne sistemske proračune tokova snaga, struja kratkog spoja, rednih kvarova, stabilnosti na male poremećaje i tranzijentne stabilnosti. U programu su implementirani i proračuni koji se baziraju na proračunu tokova snaga: redukcija mreže, sigurnost (N-1 i N-X), NTC i OTDF/PTDF. Sprega programa CASE i EnergyPlan je ostvarena preko izlaznog tekstualnog fajla EnergyPlan-a koji po satima hronološki u toku cele godine, sadrži razdvojenu ukupnu proizvodnju elektrana po tipu, ukupan konzum sistema podeljen na nekoliko podtipova, izvoz i uvoz iz regulacione oblasti. CASE učitava izlazni fajl EnergyPlan-a i ukupnu proizvodnju po tipovima elektrana CASE raspodeljuje na svaku pojedinačnu elektranu u sistemu prema unapred definisanim koeficijentima raspodele, dok ukupan konzum raspodeljuje proporcionalno postojećim opterećenjima po čvorovima mreže. Tako se za svaki sat u toku godine definiše model sistema za proračun tokova snaga. Rezultati proračuna za svaki sat se čuvaju u operativnoj memoriji CASE programa i mogu se sortirati po najopterećenijem elementu sistema, najvećoj razmeni posmatrane regulacione oblasti, gubicima u regulacionoj oblasti, proizvodnji po određenom tipu elektrane, konzumu, itd. Na ovaj način je omogućeno da se efikasno analizira rad sistema po različitim kriterijumima. Cilj ovog rada je pre svega realizacija sprege dva softverska alata, koja do sada nije bila ostvarena, kao i prikaz nekih od najznačajnih rezultata izabranih među brojnim opcijama sortiranja stanja. Rezultat rada je integracija softverskih alata koja služi na dobrobit planerskih aktivnosti u smislu njihove tehničke izvodljivosti, odnosno da preciznije ispita da li je neki perspektivni scenario realan sa aspekta tokova snaga u prenosnoj mreži.
AB  - Planning of the national energy system by looking at alternative investment decisions through annual simulations (using the EnergyPlan tool) due to its (combinatorial) complexity leaves little room for explicitness regarding the network's impact on planning decisions and therefore there is a need to look at the power flows in the network. The investment decisions that are made remain with a degree of vagueness in the technical aspect, which can be removed with this connection. The CASE tool is used for numerous system calculations of power flows, short- circuit currents, series faults, stability to small disturbances and transient stability. Calculations based on the calculation of power flows are also implemented in the program: network reduction, security (N-1 and N-X), NTC and OTDF/PTDF. The coupling of the CASE program and EnergyPlan was achieved through the output text file of EnergyPlan, which contains the total production of power plants by type, the total consumption of the system divided into several subtypes, export and import from the regulatory area. CASE loads the output file of EnergyPlan and distributes the total production by power plant types to each individual power plant in the system according to predefined distribution coefficients, while the total consumption is distributed proportionally to the existing loads by network nodes. Thus, a system model for power flow calculation is defined for each hour of the year. Calculation results for each hour are stored in the working memory of the CASE program and can be sorted by the most loaded element of the system, the largest exchange of the observed control area, losses in the control area, production by a certain type of power plant, consumption, etc. In this way, it is possible to efficiently analyse the operation of the system according to different criteria. First of all, the goal of this work is to couple the two software tools, which has not been realized until now, as well as the presentation of some of the most significant results selected from among the numerous options of state sorting. The result of the work is the integration of software tools that serve the benefit of planning activities in terms of their technical feasibility, that is, to examine more precisely whether a prospective scenario is realistic from the aspect of power flows in transmission grid.

AB  - Simulation based optimization concept has been so far presented at local and national energy systems planning levels. For the first time, the concept will be introduced at the larger modeling scale at the world level using a working IAM model, although some attempts have been made previously. This method represents a systematic way of dealing with uncertainties and combinatorial complexity when using modelling tools of very large size with significant number of possible policy inputs. The concept will be demonstrated using system dynamics platform Vensim (version 9.3.4.) for simulation and optimization. For an optimization problem formulation, 38 decision variables are selected from numerous (thousands of) input model parameters, the gross domestic product per capita has been selected for a goal function from simulation result as quantifiable policy objective, while for the constraint CO2 emissions is selected as subject to binding targets. It is possible to compile the simulation code so that optimization running time is around 10 times shorter. Preliminary results show that it is possible to implement richer optimization problems without significant increases in the running time using personal computers. The original Vensim code has been provided in Appendix.

AB  - In order to integrate more and more variable renewable energy sources (VRES) electric grids play a significant role. There is an obvious need for more interconnections and more enhanced grids with more VRES. On the other side, the monetary, material, social and spatial constraints (free corridors) impose limits on grid expansions. Robust modelling of electric grids (distribution, transmission and interconnection) at World level in integrated assessment models (IAMs) is beyond the state of the art of current computation capabilities and data availability. A number of relevant input data like length of the grids, voltage levels, rated power, and after that material prices, population density, VRES shares of generation and flexibility technologies, hourly curtailments in the energy system are not sufficient to calculate explicit limitations imposed by power flows. Therefore, the idea of this paper is that in the absence of sufficient data and computability, for the first time some expert assumptions in the form of proportions are used to represent interconnection grids as an important constraint and flexibility option for variable renewable energy production, modelled at hourly level during one year using EnergyPLAN. These assumptions are about proportions of newly integrated renewable energy between transmission and distribution grids, proportions of grids to the generation plants and their utilization. Suggested method for application in WILIAM will be illustrated.

AB  - This paper describes the importance of the interoperability in smart metering systems for modern distribution system operators. The lack of interoperability significantly increases the costs of smart metering system implementation for distribution system operators, especially the costs of purchasing new equipment. The replacement, cleanup and maintenance of electricity meters produced by different manufacturers, which are not interoperable, are also much more complex and expensive. Furthermore, without the interoperability, the system cannot be observable, i.e. the observability exists only for some particular segments of the system. This prevents many functionalities of distribution management system. In terms of interoperability, smart metering systems have gone through four different stages. A comparison of the system implementation costs for these four stages is presented for distribution system operator of Serbia.

AB  - Just in the immediate neighbourhood of the European Union (EU), the Republic of Serbia, one of the Western Balkan (WB) EU candidate countries, is lagging behind in the process of energy transition regardless of technological advances and policy instruments available. The EU created a momentum for energy transition acceleration with the European Green Deal, which has been forwarded to the WB through the Energy Community secretariat in the form of the Green Agenda; generally speaking, response in the form of National Energy and Climate Plans (NECPs) is expected in the short term. The Republic of Serbia’s Low Carbon Development Strategy with Action Plan (LCDSA) and the current Energy Strategy will be analysed, commented on, and improvements will be suggested for the acceleration of energy transition, based on the newest findings from the simulation-based optimization techniques using the sector coupling approach to achieve ambitious variable renewable energy shares. The motivation of this research is to provide decision makers in Serbia with the best available insights regarding sustainable energy system planning tools and possible shortcuts for delayed planning of activities. In addition, the purpose is to improve Serbia’s chance of benefitting from adoption of these strategies in the country’s faster transition towards EU membership. The research compares two scenarios to illustrate a possible policy shift from small hydro power plants to photovoltaics (PV). A further increase in PV and wind power plants has been simulated using the EnergyPLAN to achieve expected scenarios of 40% renewable energy share and some more ambitious ones—up to 80%, which is realistic only with the sector coupling approach.

AB  - Planning of energy systems in Serbia has long tradition and has been regularly performed for more than 60 years. Higher shares of renewable sources have been included just recently. The costs of such insufficiently planned energy future have been seen through the significant devastation of the environment and negative economic consequences of the locking into the electricity production from lignite. The draft of the National Energy and Climate Plan for Serbia, expected in the early September, could be the first in the history official document with ambition to reach higher shares of renewable sources in energy system (up to 40%) and the first step towards decarbonisation, and way forward to open negotiation with EU regarding energy sector. The first steps could be switching from small hydro to small PV systems all across the countries households, additional wind production, usage of large hydro potential, but it must be achieved through sectors coupling approach. In order to rich 80% renewable energy system and decarbonize to 25% of current level, the 30 GW of PV and 10 GW of wind have to be integrated through flexibilization of demand, flexible power plants and pumped hydro plants, heat pumps in the district heating, electrification of the transport, increase of the interconnection, and use of hydrogen in industry, transport and heating as well as firing biomass instead of lignite. The 100% renewable energy system for Serbia with ambition of Denmark or Spain is feasible, due to resource availability, energy efficiency measures, and moderate increase in consumption contrary to leading industry nations of G8 and China

AB  - Designing the energy systems for high variable renewable energy penetrations, one should look for the flexibility of an energy systems that may be provided from various sources at supply, demand or network level. The flexibility can be provided from different options including, but not limiting to: (1) electricity demand (household and industry), (2) thermal (power, CHP) plants, (3) power to heat (CHP, heat pump district/individual), (4) transport (V2G + smart charge, synthetic fuels), (5) interconnection and (6) storage (batteries, pumped hydro, rockbed, compressed air, hydrogen…). The flexibility might be provided according to different criteria: economics, technical complexity, utilization, acceptability, feasibility, material use. Further, different constraints regarding percentages, shares, emission reductions… might be set according to proclaimed sustainable energy policy in certain region. Therefore, we will simulate various flexibility options according to their availability and priority assumed by authors for each region of nine World regions (USMCA, Latin America, United Kingdom, China, Russia, South-East Asia and Oceania, Rest of the world, ) using EnergyPLAN-Python permutation framework . This way number of synthetically generated temporary scenarios before finding optimal one and the execution time is increased in comparison to optimization approach.

AB  - After the EnergyPLAN and GenOpt have coupled together for the first time, a simulation based optimization has gained popularity in energy planning articles. The advantage of the coupling method is a synergy effect and integration of three different sectors e.g. heat, electricity and transport in comparison to a typical separated method. As a result, different technical measures cannot be applied separately for each individual sector without having impact on other coupled sectors. This impact can be demonstrated as a positive and negative cumulative effect. The cumulative effect from various technical measures applied within national energy system model may be observed only with annual simulations. Therefore, in this work this synergy effect will be explained in greater details for the first time. In this paper a parallel between individual and joined contribution of different policy goals of various technical measures applied to the national energy system model has been drawn. The conclusion aims to show the significance of sector coupling for sustainable energy planning.

AB  - Smart energy systems with smart infrastructure definitely represent the fundamental ingredient in the process of integration of variable generation from renewables. Even more, the steps towards smart infrastructure should be expanded to integration of energy consumption in transport, heating/cooling, water and waste sector in order to establish observability and controllability features in the integrated energy sector. These topics, with a number of complementary issues, will be elaborated through the proposed review paper. The literature overview is quite long and focus of elaboration should be concentrated on research papers with significant contributions.
Topics that will be covered in this review paper include modern energy systems with high penetration of renewable energy sources and with smart grid wide applications, but also papers devoted to demand response programs (they enable distribution system operators to manage
consumption in response to grid imbalances), energy storage options (including electric cars with smart electric charging), smart municipal energy grids including electricity and heat production infrastructure, power to heat technologies. Transport electrification and integration of energy consumption/production in water and waste sector will be covered in this review also with the special emphasis on increasing needs for electricity due to electrification of transport and heating sector (heat pumps,...). In this review paper open questions within smart energy system will be recognized and directions for future research and investigations will be identified. A special attention to gradual transition from the conventional energy systems towards smart multi energy systems and to corresponding research results in this field will be given.

AB  - In this paper the special attention in the modelling has been given to the impact of the connection line and market conditions to the feasibility of the multi-energy microgrid with the ecotourism purpose. Microgrids for ecotourism purposes have specific hourly energy demands, including
sectors of heat, electricity, and transport. These sectors integration has been strongly practiced for achieving the synergy effect and decrease of the total costs. Therefore the HOMER software tool has been used for simulation, optimization and sensitivity analysis of the microgrid for the pre-feasibility study of the resort near Trebinje operating at open market conditions. In the analysis the attention will be for the first time given to the connection to the external (national) power grid with market capability. This pre-feasibility study will be followed with the design of the microgrid (distribution network). The results show the pre-feasibility solutions of the optimal flexible microgrid configuration for the case of Trebinje ecotourism resort. The effect of the fuels savings to the cost function changes is also shown.

The optimal configurations of used technologies (photovoltaic plants, combined heat and power plants, wind power plants) and sizing, with minimal costs, are presented and compared using three scenarios of average electricity market price 3.5 c€/kWh, 5 c€/kWh and 10 c€/kWh. Smart municipal energy grids will have an important role in future electricity markets, due to their flexibility to utilize excess electricity production from CHP and variable renewable energy sources through heat storage. This flexibility enables the levelized costs of energy within smart municipal energy grids to decrease below electricity market prices even in case of fuel price disturbances.  With initial costs in the range 0- 3,931,882 €, it has been shown that economical and environmental benefits of smart municipal energy grids are: the internal rate of return in the range 6.87-15.3%, and CO2 emissions in the range from -4,885,203 to 5,165,780 kg/year.  The resulting realistic number of hours of operation of combined heat and power plants obtained by simulations is in the range 2,410- 7,849 hours/year.
