| Summary: | In this paper, a typical-operation-curve generation method of a hydrogen energy storage system operating under the mode of stabilizing wind power fluctuations is proposed. This method is used to optimize the power and capacity configuration of the energy storage system. The time series curves of the charging and discharging powers of the hydrogen energy storage are obtained by EMD decomposition, and the curves are classified according to the similarities and differences of the characteristic parameters in different time periods. After the classification, typical charging and discharging power values of each type of curve at each moment are obtained by a cloud model, and then, typical operation curves of each type are obtained by integration. On this basis, the power and capacity of the energy storage system are optimized with the objective of economic optimization through the MATLAB CPLEX toolbox. Combined with the measured data of a wind farm with an installed capacity of 400 MW in Northeast China, the validity and rationality of the typical operation curve generation method proposed in this paper are verified.
