“…According to the comprehensive status of power quality obtained at PCC, the reactive power ΔQ needing to be regulated is calculated, and then, the reactive power execution of the inverter is obtained through the feeder distribution algorithm and the inverter group distribution algorithm, as well as the power iteration between groups [32]. e scheme in Figure 3 is a dynamic real-time tracking control [28], so the oscillation amplitude of the control effect is related to the interval period between two commands. Assuming that the normally control oscillation will not exceed the system limits, and the safety threshold is set at PCC, the stabilization device will be started when the disturbance exceeds the system requirements.…”

With the development of new energy, a cost-effective reactive power compensation scheme is essential to the voltage stability of the power system for small-capacity distributed generation. This paper proposes a coordinated control scheme of inverter cluster which is based on the reactive power support capability of the photovoltaic inverter. Moreover, by using power angle vectors, a reactive power distribution algorithm is proposed to solve the poor power quality of the point of common coupling connecting source and load in the distributed generation station. Simulations verify the performance of the algorithm is better than the conventional static capacity distribute algorithm and dynamic residual margin distribute algorithm. Finally, the effectiveness of the reactive power compensation scheme and distribution strategy for improving power quality and regulation ability proposed in this paper is verified by operation experiments in the actual power station.
