Optimal allocation method of grid-side hybrid energy storage for renewable energy consumption
Energy storage plays an extremely important role in the field of renewable energy consumption.Large-scale construction of energy storage will help promotion of the integration of renewable energy into the power system and help to achieve the＂dual carbon＂ goal.However,the investment and construction cost of energy storage is rel-atively high,and careless allocation of energy storage will lead to a large waste of funds.Therefore,it is necessary to study the optimal allocation method of energy storage for renewable energy consumption,taking into account of both the consumption effect of renewable energy and the investment funds.This paper proposes a two-stage energy storage optimization method.In the first stage,the operation simulation of the power system is performed to deter-mine the optimal energy storage type selection scheme.In the second stage,a dual-objective optimization model to minimize the investment cost and the curtailment of wind and solar power is constructed,and the model is solved to obtain a realistic energy storage schedule scheme.The case study analysis shows that the proposed method in this paper can greatly increase the consumption of renewable energy and reduce the investment cost.
