Evaluation of grid connected wind power plants

A novel generation reliability model of wind power plants and the corresponding calculating method are given, which takes into account the wake effects of wind turbine generators and the wind correlation among wind power plants. Some useful concepts such as the efficiency matrix, equivalent power curve, etc. are defined. The model cannot only be used in power system probabilistic production simulation, but also in stochastic power flow analysis. Power system probabilistic production simulation is utilized to evaluate grid connected wind power plants. The method of calculating fuel savings, pollutant emission reduction, capacity credit and avoided cost of wind power plants is described in detail.
