Optimization of bearing capacity of distribution network with wide access of electric vehicles and distributed generation

The large-scale access of electric vehicles and photovoltaics to the power grid has a significant impact to the Safety, stability and economy of the distribution network operation. According to the main factors that introduce volatility and instability to the distribution network., this paper examines the charging behaviors of electric vehicles, and establishes a photovoltaic output and electric vehicle load model on typical days. In addition, the co-evolutionary algorithm is used to maximize the photovoltaic access capacity on the basis of minimizing the network loss as much as possible, in order to determine the optimal location of photovoltaic access.
