Results show that ESS function well on the basis of the proposed model and control scheme, and also demonstrate the superiority of the novel algorithm. Energy storage systems (ESS) are indispensable building blocks of power systems with a high share of variable renewable energy.
As energy-limited resources, ESS should be carefully modeled in uncertainty-aware multistage dispatch. On the modeling side, we develop a two-stage model for ESS that respects the nonanticipativity of multistage dispatch, and implement it into a distributionally robust model predictive control scheme.
