电力市场下虚拟电厂协同运行优化策略研究

Research on Optimization Strategy of Virtual Power Plant Cooperative Operation in Power Market

摘要: 构建清洁低碳、安全充裕、经济高效、供需协同、灵活智能的新型电力系统背景下，新能源装机在全国发电总装机容量中占比不断提升，其随机性、间歇性、波动性等特征不利于电力系统安全稳定。虚拟电厂可以高效聚合灵活性资源，实现多类型资源调度优化，有效挖掘灵活性资源调节能力进而促进新能源消纳。虚拟电厂处于从邀约型迈入市场化的转型期，已有省份开展了虚拟电厂参与中长期＋现货市场模式探索，但对运行优化策略研究较少。本研究构建了现货市场下虚拟电厂运行优化模型，并通过算例仿真验证了模型在电力市场环境下虚拟电厂内部资源调度需求方面的有效性。

Abstract: Under the background of building a clean and low-carbon, safe and abundant, economical and efficient, supply-demand coordination, flexible and intelligent new power system, the installed capacity of new energy in the country’s total installed capacity is constantly increasing, and its randomness, intermittence, volatility and other characteristics are not conducive to the security and stability of the power system. Virtual power plant can efficiently aggregate flexible resources, realize multi-type resource scheduling optimization, and effectively tap the adjustment ability of flexible resources to promote the consumption of new energy. The virtual power plant is in the transition from the invitation type to the marketization. Some provinces have carried out the exploration of the mode of virtual power plant participating in the medium and long term + spot market, but there are few researches on the operation optimization strategy. In this paper, a virtual power plant operation optimization model is constructed under the spot market environment, and the effectiveness of the model in the internal resource scheduling requirements of virtual power plants is verified by simulation examples.
