Research on Auxiliary Decision-making Method of Energy Storage Configuration Based under Uncertainty

In this paper, it is focused on the auxiliary decision-making problem of energy storage(ES) configuration. An expected value model of ES configuration considering the uncertainty of demand scenario is established based on stochastic programming theory. And the corresponding algorithm steps of model solving based on scenarios clustering and genetic algorithm are proposed. A case study based on a typical regional power system is done to verify the feasibility and validity of the method mentioned above. The results show that this decision-making method of ES configuration based on expectation model can quantify the uncertainty of demand scenario caused by randomness of renewable energy generation, optimize the target expectation value.#$NLKeywords: uncertainty; energy storage configuration; stochastic programming; expected value.
