Multi-scenario two-stage dispatch decision-making model for wind farm with integrated energy storage

With the consideration of its fluctuation and randomness, the uncertainty of wind power is introduced to the dispatch model of power system with wind farm and a two-stage decision-making model including day-ahead unit commitment and intra-day rolling economic dispatch is developed. The unit commitment model applies the scenario set to describe the uncertainty of wind power and considers the wind curtailment and load shedding to improve the stable and economic system operation, while the intra-day rolling economic dispatch model applies the wind curtailment and load shedding as the slack variables to enhance its convergence. The two-stage model includes the energy storage system to suppress the fluctuation of wind power. Numerical results show that the proposed model suppresses effectively the influence of wind power uncertainty and improves the robustness of dispatch decision-making.
