Optimal Planning of High Penetration Distributed Photovoltaic with Considering Grid Reinforcement

With the continuous strong supportive policies, distributed photovoltaic have developed rapidly in a high penetration in some regions, which requires grid reinforcement and is imposed to the curtailment risks. In response to the grid reinforcement costs, reduced losses, delayed grid investment and other costs or benefits associated with the access of high penetration distributed photovoltaic; this paper proposes a comprehensive cost-benefit analytical method in consideration of grid reinforcement. Analytical results of 8760 h power flow are acquired for optimized planning of the access of high penetration distributed photovoltaic. The research results may be valuable references for the scientific planning of high penetration distributed photovoltaic.
