Intermittent wind generation in optimal power flow dispatching
IET Generation, Transmission & Distribution, 2009 A stochastic model of wind generation in an optimal power flow (OPF) dispatching program is presented. The model includes the error in wind power forecasts using a probability or relative frequency histogram. Compared with the deterministic OPF, the proposed model allows the coordination of wind and thermal power while accounting for (i) the expected ...
