Economic optimal dispatching of power system with wind power-pumped storage-thermal power joint operation

摘要

Large-scale wind power access to power grids directly will have a large impact for power system. To solve this problem, the pumped storage power station is widely used because of the large capacity of storage and technology maturity. Based on the research of wind power and pumped storage power station to the influence of system load curve, this paper established a optimization model of wind power-pumped storage-thermal power joint operation and solved by PSO(particle swam optimization) algorithm. The calculation example simulated by MATLAB showed that the output of the wind power can be smoothed and the controllability.
