A risk-averse optimization model for trading wind energy in a market environment under uncertainty

In this paper, a stochastic programming approach is proposed for trading wind energy in a market environment under uncertainty. Uncertainty in the energy market prices is the main cause of high volatility of profits achieved by power producers. The volatile and intermittent nature of wind energy represents another source of uncertainty. Hence, each uncertain parameter is modeled by scenarios, where each scenario represents a plausible realization of the uncertain parameters with an associated occurrence probability. Also, an appropriate risk measurement is considered. The proposed approach is applied on a realistic case study, based on a wind farm in Portugal. Finally, conclusions are duly drawn.

► We model uncertainties on energy market prices and wind power production. ► A hybrid intelligent approach generates price-wind power scenarios. ► Risk aversion is also incorporated in the proposed stochastic programming approach. ► A realistic case study, based on a wind farm in Portugal, is provided. ► Our approach allows selecting the best solution according to the desired risk exposure level.
