摘　　要：为提升新能源场站配套储能设施的经济性和灵活性,以及提高大规模新能源场站向大用户直供电的稳定性和并网友好性,提出了发电侧混合储能的两阶段鲁棒配置与优化运行策略。第一阶段基于需求功率信号的经验模态和希尔伯特-黄变换分解,考虑储能投资成本和新能源场站供能与并网需求,构建鲁棒配置模型。第二阶段在第一阶段优化配置方案的基础上,以降低净负荷波动为目标构建优化运行模型,满足场站供能和并网需求。通过某省实际风电场和负荷数据的算例分析,验证了所提模型的竞争性和有效性,为新能源场站与储能的协同发展提供了技术支持和决策参考。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.
