为应对高比例新能源并网所导致的波动性与消纳挑战，提升抽水蓄能电站在多能互补系统中的经济调度价值与灵活调节作用，以水—风—光—蓄多能互补联合发电系统为对象，开展以抽水蓄能灵活调度效益最大化为导向的短期优化调度研究。引入分时电价机制，构建以系统总发电量最大化、剩余负荷波动最小及抽水蓄能灵活调度效益最大为核心的多目标优化调度模型，并采用融合混沌映射初始化种群与自适应交叉与变异策略的改进NSGA-Ⅲ算法进行求解。案例结果表明，所提模型与改进算法在各类典型场景和极端场景下均实现技术性能与经济效益的协同优化，在保障风光消纳与水电高效运行的同时，显著提升了抽水蓄能灵活调度效益指标。该短期策略不仅强化了抽水蓄能的调节主导作用，在确保自身经济效益的同时充分发挥了水电与抽水蓄能的协同调节能力，也为清洁能源基地的规划与调度运行提供理论参考。
Abstract：To address the challenges of volatility and accommodation caused by the integration of high-penetration renewable energy, and to enhance the economic dispatch value and flexible regulation role of pumped storage power stations in multi-energy complementary systems, this paper focuses on a hydro-wind-solar-pumped storage integrated generation system, and conducts short-term optimal dispatch research oriented towards maximizing the flexible dispatch benefit of pumped storage. By introducing a time-of-use electricity pricing mechanism, a multi-objective optimization dispatch model is constructed with the core objectives of maximizing total system power generation, minimizing residual load fluctuation, and maximizing the flexible dispatch benefit of pumped storage. The model is solved using an improved NSGA-III algorithm that incorporates chaotic map for population initialization and adaptive crossover and mutation strategies. Case study results show that the proposed model and improved algorithm achieve synergistic optimization of technical performance and economic benefits across various typical and extreme scenarios. While ensuring the accommodation of wind and solar power and the efficient operation of hydropower, the index for the flexible dispatch benefit of pumped storage is significantly improved. This short-term strategy not only strengthens the leading regulatory role of pumped storage that ensures its own economic benefit while fully leveraging the coordinated regulation capability of hydropower and pumped storage, but also provides a theoretical reference for the planning, dispatch, and operation of clean energy bases.
