要約(日本語): Nowadays, Distributed Generation (DG), as a new power source, has played an important role in transmission and distribution networks. Various coordinated control strategies between conventional power grid and DGs have been realized. With the penetration of large amount of DGs, there is a possibility that DGs could contribute to mitigate voltage instability issues by using reactive power control when an operating point is approaching the stability limit.In previous research, the authors have developed a control strategy to dispatch optimal reactive power output considering active power curtailment under power capacity constraint of PV plants, aiming to maximize Loading Margin (LM). Although the improvement of LM was significant, the accuracy of the analysis might not be enough as inverter current limit was not considered. Therefore, in this paper, the control effect is reevaluated with the current limit of PCSs. One-machine infinite-bus system model was used for this simulation and continuation power flow (CPF) method was applied to obtain LM.
