A Method for Maximizing Grid Connection of Photovoltaics Based on Coordinated Planning of a Combined Generation and Transmission System
In view of the strong uncertainty of photovoltaics and the problems caused by large-scale integration of photo-voltaics to the grid,it is necessary to upgrade the system by adding new dispatchable units and transmission lines.A joint optimization model of power generation and transmission is proposed to maximize the scale of photovoltaic power genera-tion capacity.The Benders decomposition method is used to solve the computational complexity of the model.The solution of the model further identifies the optimal solar photovoltaic size and location as well as the potentially required energy cut.Analysis on a case of 6-node system shows that the proposed joint optimization planning is more effective than the separate planning of power generation and transmission with and without considering photovoltaic grid connection.
