Ever increasing electricity demand as well as the rapid depletion of fossil fuels have increased the need for hybrid power systems that integrate distributed energy resource (DER) systems; such as solar photovoltaic (PV) systems and battery storage systems; with electrical grids. Therefore, this present study used MATLAB/Simulink to demonstrate the ability of DER inverters to provide reactive power that regulates grid voltage, decreases the total harmonic distortion (THD), decreases the amount of active power lost, and improves the capacity and power quality of a modified IEEE 13-bus test system. The study found that the injection/Absorption of the reactive power from a 400KW (PV-Battery) system in bus 675, 500KW (PV-Battery) system in bus 671, and 200 KW.h battery storage system in bus 634 decreased the power output of the main generator by 24.6%. When used in situ, the reactive power capability of the DER inverters significantly improved the voltage while an injection of reactive power decreased the THD voltage of bus 675 phase B by 81.26% when absorbing reactive power as well as decreased active power losses.

Stale rosnące zapotrzebowanie na energię elektryczną oraz szybkie wyczerpywanie się paliw kopalnych zwiększyły zapotrzebowanie na hybrydowe systemy zasilania, które integrują systemy rozproszonych źródeł energii (DER); takie jak systemy fotowoltaiczne (PV) i systemy magazynowania baterii; z sieciami elektrycznymi. Dlatego w niniejszym badaniu wykorzystano MATLAB/Simulink do wykazania zdolności falowników DER do dostarczania mocy biernej, która reguluje napięcie sieci, zmniejsza całkowite zniekształcenia harmoniczne (THD), zmniejsza ilość utraconej mocy czynnej oraz poprawia wydajność i jakość mocy zmodyfikowany system testowy IEEE 13-bus. Badanie wykazało, że wtrysk/pobór mocy biernej z systemu 400KW (PV-Battery) w magistrali 675, 500KW (PV-Battery) w magistrali 671 i 200KW.h systemu magazynowania baterii w magistrali 634 zmniejszyło moc moc głównego generatora o 24,6%. W przypadku zastosowania in situ, moc bierna falowników DER znacznie poprawiła napięcie, podczas gdy wprowadzenie mocy biernej zmniejszyło napięcie THD szyny 675 fazy B o 81,26% podczas pochłaniania mocy biernej, a także zmniejszyło straty mocy czynnej.
