  • 摘要: 在可再生能源发电并网渗透率不断提高以及综合能源系统高速发展的背景下,提出一种电热氢多元储能(multi-energy storage, MES)优化调度方法。首先,研究构建MES系统结构和设备模型。在此基础上,考虑储能购售分时价格的影响,以储能经济效益最大、能量损耗最小以及储能调度参与下微网与外网间功率波动最小为目标,建立储能多目标优化调度模型,达到经济性、高效性、平稳性的统一效果。最后以某具体的算例对所提模型进行仿真分析,重点研究MES的经济效益以及兼顾能量损耗和功率波动对经济效益的影响,结果验证了所提模型的科学性及有效性。

     

    Abstract: With the increasing penetration rate of renewable energy generation and the rapid development of integrated energy system, an electric-thermal-hydrogen multi-energy storage (MES) optimized scheduling method is proposed. Firstly, the framework and equipment model of MES are established. On this basis, the influence of time-of-use pricing is taken into consideration, and a multi-objective optimal dispatch model of MES is proposed to achieve the unified effect of economy, efficiency and stationarity. The objectives of the model is to maximize the economic benefit, minimize energy loss and minimize power fluctuation between microgrid and external grid with participation of energy storage dispatching. Finally, a specific example is used to simulate and analyze the economic benefits of MES and the influence of energy loss and power fluctuation on economic benefits. The results show that the proposed model is scientific and effective.
