Research on optimization of electrical connecting network for a solar photovoltaic power Plant

Through the establishment the collection network optimization models of the photovoltaic power plant, each group of solar battery, inverter and step-up transformer can be composed a connection unit, a photovoltaic power station electrical investment cost optimization can be induced to two kinds of problems, one is a group of discrete variables optimum solution and the other is the connection topology optimization of the photovoltaic inverter unit. Using clustering algorithm, sectoral segmentation algorithm and the Prime algorithm to solve the optimization model and obtained the optimal topology structure of the discrete points, which has high practicability in engineering.
