Energy Efficient Power Supply of Autonomous Consumers Using Hybrid (Photovoltaic and Diesel Aggregates) Sources

Abstract

The energy efficient solution of autonomous power supply of consumers during the year, by using of a hybrid (photovoltaic and diesel aggregates) sources in the monastery Chilandar is presented in this paper. In details optimal load of diesel aggregate is discussed with a minimum consumption of fossil fuels. The results of the one year exploitation of the electricity generated from photovoltaic panels in our conditions are presented as well. Taking into consideration the specific location and importance of the monastery, the current and future needs of the monastery and particular way of life of the monks, the new hybrid system for the daily consumption of 400 kWh of energy and peak load of 80 kW has been designed and explained. It is based on the combined use of the three diesel power generators 2 x 40 kW and 80 kW, photovoltaic rated power 75 kW and battery pack for energy storage of 400 kWh. The primary objective of the new system is to reduce the consumption of diesel fuel and operating costs for the system power consumption.

U ovom radu je opisano energetski efikasno rešenje autonomnog napajanja potrošača tokom godine, korišćenjem hibridnog (solarne i dizel agregata) izvora u manastiru Hilandaru. Detaljnije je razmotreno optimalno opterećenje dizel agregata sa minimalnom potrošnjom fosilnih goriva. Prikazani su rezultati jednogodišnjeg ispitivanja, u našim uslovima, dobijanja električne energije iz fotonaponskih panela. Imajući u vidu specifičnu lokaciju i značaj manastira, sadašnje i buduće potrebe manastira i specifičan način života monaha, nov hibridni sistem za dnevnu potrošnju od 400 kWh električne energije i vršno opterećenje od 80 kW je projektovan i objašnjen. Zasniva na kombinovanom korišćenju tri dizel generatora snage 2 x 40 kW i 80 kW, fotonaponskih nominalne snage 75 kW i baterije za skladištenje energije od 400 kW. Primarni cilj novog sistema je da smanji potrošnju dizel goriva i operativnih troškova za potrošnju energije sistema.
