Dynamic economic dispatch considering wind power penetration based on IPSO

With the increase of wind power in power systems,the influence of wind farms penetration should be considered in economic dispatch.In this paper,a n improved particle swarm optimization(I PSO) i s proposed for solving the problem of dynamic economic dispatch(D ED).In this optimization model,the constraints of up spinning reserve and down spinning reserve are introduced to deal with the influence of wind power forecast errors on DED,and energy cost of routine unitis is considered in the objective function.The case studies are conducted based on a typical 10 units test power system.The effectiveness and feasibility of the proposed method are demonstrated by comparing its performance with that of other approaches.This proposed method can save much fuel cost and has high application value.
