Abstract

In order to improve the absorption capacity of distributed photovoltaics （DPV） in the distribution network, a DPV hosting capacity enhancement model considering transfer reconstruction and reactive power control is proposed by using reactive power compensation capacitor banks （CB） and static var compensators （SVC） to control reactive power, as well as network reconstruction for transfer operation in the distribution network. On this basis, a probability uncertainty set for DPV output and load is constructed by comprehensively considering the 1 norm and ∞ norm, and a robust optimization model for DPV hosting capacity distribution considering transfer supply reconstruction and reactive power control is established. The simulation results of a case study conducted on an improved 99-bus system show that the proposed distributed photovoltaic hosting capacity enhancement strategy, which considers power supply restructuring and reactive power control, can effectively improve the DPV consumption rate of the distribution network, improve the stability and economy of operation.
