随着能源和信息通信技术的快速发展,新型负荷资源参与运行控制已成为电网运行的重要成分。新型负荷资源的响应存在差异性和不确定性,准确地量化评估电网新型负荷资源的响应性能成为电网运行的重要任务。为此,在电网运行控制角度,建立了电网新型负荷资源需求响应性能评估体系,定义了反映响应及时性、响应准确性、响应可靠性和响应利用率的各项指标和计算方法,并通过示例,演示了需求响应各项响应性能指标的计算过程,通过对3种不同响应的响应性能指标的比较,验证了提出的响应性能量化评估指标符合响应性能的直观判断,还能提供更全面的评估信息,能够准确评估新型负荷资源的响应性能,为电网运行控制、需求响应的考核结算提供了依据。

With the rapid development of energy and information communication technology,the participation of novel demand resources in system operation and control has become an important part of grid operation.Due to the inherited differences and uncertainties of demand response,accurately quantifying the response performance of demand response resources has become the important tasks of grid operation.For this a demand response performance evaluation system is establisged from the perspective of power system operation and control,defines various indicators to assess the timeliness,accuracy,reliability and utilization of demand response and provides corresponding calculation methods.An example demand response case is used to demonstrate how to calculate the performance indicators quantitatively.Through comparison of the response performance indicators of three different responses,it is verified that the proposed quantitative evaluation indicators of response performance conform to the intuitive judgment of response performance and also provide more comprehensive evaluation information.The response performance indicators can accurately evaluate the response performance of novel demand response resources,and provide the basis for system operations,settlements and compliance.
