新能源场站惯量支撑与频率响应特性研究
Research on Inertia Support and Frequency Response Characteristics in New Energy Stations
摘要
Abstract
In response to the integration of wind power,photovoltaic,and other new energy stations on a large scale,which gradually transforms traditional power grid into low-inertia,weak-damping system dominated by asynchronous power sources,leading to significant changes in dynamic characteristics of system frequency,this paper delves into the inertia support capabilities of wind power,photovoltaic,and energy storage systems within these new energy stations from a control perspective,and clarifies the energy sources,response strategies,and functional roles of inertia support provided by wind power,photovoltaic,and energy storage components.Additionally,a sophisticated frequency dynamic analysis model for power systems is developed,encompassing new energy stations,to analyze the intricate impact of factors such as inertia,damping,and difference adjustment coefficients on system frequency fluctuations.Crucially,the research underscores that under the high penetration of new energy,the reduction in system rotational inertia poses formidable challenges to frequency stability.Thus,embarking on modifications to enhance the inertia support functions of new energy stations is identified as a pivotal strategy to mitigate the challenges associated with new energy integration,which is of paramount importance in safeguarding the secure and stable operation of the power grid.关键词
