Evaluation method of distributed photovoltaic hosting capacity of distribution network considering economic quality
In order to quantify and evaluate the comprehensive impact of high proportion distributed photovoltaic access to the distribution network,an evaluation method of distributed photovoltaic hosting capacity of distribution network considering economic quality is proposed.Firstly,a comprehensive evaluation index system of distribution network hosting capacity is established from three aspects:distributed photovoltaic grid connection characteristics,distributed photovoltaic utilization characteristics and distribution network adaptability.Then,taking photovoltaic access quantity and economic quality into consideration,the photovoltaic grid-connected capacity optimization model is established,and different grid-connected capacity access schemes are formed according to the different development requirements of distributed photovoltaic.Finally,the state space evaluation method is used to comprehensively evaluate the distributed photovoltaic hosting capacity of distribution network.Through the simulation analysis of IEEE33 node distribution network,the results show that the proposed hosting capacity evaluation method can comprehensively and objectively reflect the hosting capacity of the distribution network for distributed photovoltaic.
