Optimal power flow with consideration of wind generation cost

This paper discusses the solution of optimal power flow incorporating wind generation cost. A new model of wind generation cost is presented based on the probability distribution of wind farm power output. In this model, the wind farm generation cost consists of two components: the reserve capacity cost and the environmental benefit loss. Both of the two components could be attributed to the intermittence and uncertainties of wind power. A self-adaptive evolutionary programming method is employed to solve the OPF with wind power incorporated. A case study is conduced based on the IEEE New England test system (10-Geneartor-39-Bus) as benchmark. The simulation results demonstrate the effectiveness and validity of the proposed model and method.
