Abstract
Integrated wind farms exert a growing influence in the economic operation of power system. Wind power is a form of intermittent and random energy. This paper introduces a model including 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 andthermal power while accounting for the expected penalty cost for not using all available wind power and the expected cost of calling up power reserves because of wind power shortage.Simulation results are presented for cases where the forecasting error histogram is eitherderived from historical data or estimated by a bimodal normal distribution.
