Distributed Photovoltaic Access for Optimal Siting and Sizing of Distribution Grids

Distributed photovoltaic (DPV) access to the distribution network if the installation location, capacity and other unreasonable will cause many adverse effects on the power system, distributed photovoltaic grid integration must be considered in the planning. In order to solve the optimization problem of distributed PV access to the distribution network, we briefly explain the impact of distributed PV on the voltage quality and network loss of the distribution network, analyze the typical topology of distributed PV access, and give the optimization process of distributed PV access to the distribution network, and establish an optimization model for distributed PV access to the distribution network that considers the voltage quality and the loss of the network, and verify the validity of the model with the analysis of the examples. The validity of the model is verified by case analysis, which provides an effective idea for the study of siting and capacity determination of distributed PV access to the distribution network.
