摘　　要：华东电力系统新能源占比快速提升,系统中的旋转惯量与调频资源不断下降,将对系统频率的抗扰性和稳定性造成威胁。现有研究集中于新能源系统惯量及一次调频技术的开发与应用,对风电、光伏、储能等多种新能源频率响应技术的中长期发展优先级研究较少。为此,展开了华东电网系统的协同调频技术演进路径研究。首先,基于华东电网历年扰动事件分析了系统多源协同频率响应体系,通过构建决策实验室模型量化分析了各调频主体在扰动事件中的影响因素。其次,以影响因素为权重分配前瞻性地分析了华东电网协同调频技术的发展优先级及其最优演化路径,为华东电网新能源调频技术的有序发展提供了理论基础,可支撑华东电网在新能源高比例馈入下的频率安全性。The rapid increase in the proportion of renewable energy in the East China Power Grid System and the continuous decline in the rotational inertia and frequency modulation resources in the system will pose a threat to the system's frequency immunity and stability.The existing research focuses on the development and application of renewable energy system inertia and primary frequency modulation technology,while there is less research on the medium and long-term development priorities of multiple renewable energy frequency response technologies such as wind power,photovoltaic,and energy storage.Therefore,a research on the evolution path of collaborative frequency modulation technology in the East China Power Grid System was proposed.Firstly,based on the disturbance events of the East China Power Grid over the years,the system's multi-source collaborative frequency response system was analyzed,and the influencing factors of various frequency modulation entities in the disturbance events were quantitatively analyzed by decision-making trial and evaluation laboratory(DEMATEL)model.Secondly,the development priority and optimal evolution path of collaborative frequency modulation technology in East China Power Grid were prospectively analyzed based on the weight distribution of influencing factors,providing a theoretical basis for the orderly development of renewable energy frequency modulation technology in East China Power Grid.This has consolidated the frequency security of the East China Power Grid under the high proportion of new energy feeds.
