To enhance the economic and operational flexibility of accompanying energy storage facilities in new energy power stations, as well as to improve the stability of supplying electricity directly to large users and the grid-friendliness of large-scale new energy power stations, a two-stage robust configuration and optimized operation strategy for hybrid energy storage on the generation side was proposed. In the first stage, based on the empirical mode decomposition and Hilbert-Huang transform of demand power signals, considering the investment cost of energy storage and the supply-demand requirements of new energy power stations and grid integration, a robust configuration model for various types of energy storage units in the hybrid system was constructed. In the second stage, with the first-stage optimized configuration as a constraint, an optimization model for the operation of hybrid energy storage was developed with the objective of reducing net load fluctuations while meeting the power supply requirements of the power station and grid integration. The effectiveness and competitiveness of the proposed models and strategies were demonstrated through case studies using actual wind power and load data from a certain province, providing technical support and decision-making references for the coordinated development of new energy power stations and energy storage.
