Aiming at the problem of power fluctuation and safe operation caused by wind power integration

a multi-objective cooperative economic dispatch optimization method considering SVC and energy storage is proposed. Taking the typical daily operation as an example

this paper establishes a multi-objective optimization model of economic dispatch with the objective functions of system comprehensive operation cost

voltage deviation and system network loss minimization. In the optimization process

the objectives of economic dispatch and reactive power optimization model are iteratively coordinated to obtain the optimal solution which takes into account the economy and security of power grid. The results are compared with the Pareto frontier obtained by using the weight coefficient method. The simulation results of IEEE RTS-24 bus system verify the rationality and feasibility of the algorithm.
