In order to achieve the goal of economical and low carbonization while optimizing the dispatching of power system, an optimization model for the joint dispatch of wind power and pumped storage is established which considers the demand response with the goal of minimizing the cost of power generation and carbon emissions. The branch and bound algorithm is employed to solve the multi-objective optimization model. A two-player zero-sum game model is formulated to balance the multiple optimization goals, and the multi-objective optimization problem is converted to a single-objective optimization problem with the weighted coefficients. The case studies show that both the cost of power generation and the carbon emissions of the system have decreased after the introduction of demand response and pumped-storage units, and the benefits of co-scheduling are obvious.
