Photovoltaic power generation is widely used in power systems due to its abundant resources and cleanness. However, the emerging high penetration distributed photovoltaic will affect the security and stability of the distribution network and also have an impact on voltage violation, line loss, and power flow. Therefore, the scheme of deeply penetrated distributed photovoltaic needs to be evaluated. In this article, a model based on the entropy weight method (EWM) and the technique for order preference by similarity to ideal solution (TOPSIS) has been constructed to evaluate photovoltaic integration performance. The evaluation model is proposed from three-phase voltages, power flows, and line losses, helping to find out the suitable scheme for photovoltaic integration. This paper can be applied to obtain the optimal integration scheme and provide suggestions for distributed photovoltaic integration to the grid.
