The Optimal Dispatch with Combination of Wind Power and Photovoltaic Power Systems

Developing new energy such as wind power and photovoltaic power is the main way to solve our energy problems. However, the volatility of wind power and photovoltaicpowerwill impact the grid. The changes of wind power and photovoltaic power have complementary characteristics. It can effectively reduce the impact to the grid by combining them. This paper studies the optimal dispatch modeling problem with combination of wind power and photovoltaic power systems,establishes the optimal scheduling model of a power system including wind power and photovoltaic power considering the environmental benefits and spare capacity changing,and conducts a simulation calculation to verify the validity of the method.
