Abstract: A large-scale battery energy storage station (LS-BESS) directly dispatched by grid operators has operational advantages of power-type and energy-type storages. It can help address the power and electricity energy imbalance problems caused by high-proportion wind power in the grid and ensure the secure, reliable, and economic operations of power systems together with conventional power generation units. To enable power systems to resist any power disturbance in the prediction failure set and cope with wind power and load fluctuations while meeting the load demand, a day-ahead dispatch optimization model to minimize operation costs on the dispatch day is established, which utilizes the regulation advantages of conventional units and a LS-BESS to participate in regulation services of diverse timescales and effectively achieve the coordination of various service demands. To account for wind power variations on the dispatch day, a robust optimization (RO) approach based on the budget uncertainty set is proposed, which improves the robustness and economy of grid operations against realistic uncertainties. The effectiveness of the day-ahead dispatch strategy is verified through extensive simulations and comparisons, which can better serve modern power systems with high penetration of wind power.
