A Novel Coordinated Control System to Reactive Power Compensation of Photovoltaic Inverter Clusters

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