Microgrid integrated with renewable energy source (RES) is experiencing a rapid development nowadays. Many technical challenges appear with the high penetration of RES into the microgrid. One of the most important issues is the voltage rise at the point of common coupling (PCC). The voltage profile of PCC not only depends on the active and reactive powers, but also on the ratio (R/X) of line impedance. In order to mitigate the voltage rise, two control strategies are discussed, namely, active power curtailment and reactive power absorption. Theoretical analysis and experiment results are presented to validate the effectiveness of the proposed control schemes for voltage rise mitigation. It indicates that both control strategies may work well, but reactive power control enables the higher penetration of RES.

W celu zmniejszenia niebezpieczeństwa zwiększania napięcia w sieci microgrid z odnawialnymi źródłami energii zaproponowano dwie strategie – ograniczenie mocy czynnej i absorpcja mocy biernej. Przedstawiono analizę teoretyczną i wyniki eksperymentów. Wyniki te wskazują, że metoda sterowania mocą bierną jest bardziej skuteczna.
