摘要
我国电力现货市场发电侧拥有高市场集中度的特点,市场力的滥用辨识变得尤为重要。对美国事前市场力的辨识方法进行了详细综述,分析指出了行为-影响测试方法更适用于我国电力现货市场。在此基础上,进一步研究提出了高市场集中度下的事前-事后市场力辨识方法,包括用于辨识潜在市场力的剩余供给指标测试法和市场模拟仿真法、用于辨识事中市场力的行为-影响测试方法和从市场整体运行情况、用户侧、发电侧和电网侧4个维度进行全面评估的事后市场力辨识方法。最后,通过算例分析,论证了所提市场力辨识方法的合理性和可行性。
The generation side of China's electricity spot market has a high market concentration,and identifying the abuse of market power has become particularly important.This article provides a detailed overview of the identification methods for the ex-ante market power in the United States.It analyzes and points out that the behavior-impact testing method suits China's electricity spot market more.On this basis,this article further studies and proposes ex-ante and ex-post market power identification methods under high market concentration,including residual supply indicator testing method and market simulation method for identifying potential market power,a behavior-impact testing method for identifying market power during events,and post-event market power identification method for comprehensive evaluation from four dimensions:overall market operation,user side,power generation side,and grid side.Finally,the rationality and feasibility of the market power identification method proposed in this paper were demonstrated through numerical analysis.
