Optimal Scheduling Considering Wind-Solar-Pumped Storage Economy and Fairness under Non-cooperative Game

Aiming at the fairness and economy of power system dispatching, considering the maximum profit of each generation unit, a non cooperative game model with wind power, photovoltaic power and pumped storage power station as game participants is established. This model takes the income of power generation unit as the optimization objective, uses Gini coefficient to represent fairness and takes it as one of the constraints to establish a mathematical model. CPLEX is used to solve the models in three different scenarios and verify the correctness and effectiveness of the models. The results show that the addition of pumped storage power station can not only improve the utilization rate of renewable energy, but also increase the system income; when the Nash equilibrium condition is reached, the total system income is higher than that under general conditions; the increase of Gini coefficient will lead to the increase of generation cost of dispatching system, while the economic benefit will be relatively reduced.
