摘要
随着风光等可再生能源及多变流器等电力电子设备在配电系统中渗透率逐步提高,“双高”配电系统面临诸多问题与挑战。高比例可再生能源出力的不确定性及波动性,高比例电力电子设备大量存在于控制环节带来的低惯性及弱阻尼等新问题均为配电系统安全运行带来了新的挑战。该文从“双高”特性对配电系统影响的不同时空尺度出发,归纳配电系统新形势下面临的问题,分析这些新问题的产生机理,并针对现有的解决方案展开探讨。最后尝试对“双高”配电系统的发展进行展望。
With the gradual increase in the penetration rate of renewable energy sources such as wind and solar and power electronic equipment such as multi-converters in the distribution system(“double high”),power distribution system faces many problems and challenges.New problems such as low inertia and weak damping caused by the uncertainty and volatility of high proportion of renewable energy output and high proportion power electronic equipment embedding together bring new challenges to the safe operation of power distribution system.This paper summarizes the problems faced by the distribution system under the new situation,analyzes the mechanism of these new problems,and discusses the existing solutions based on the influence of“double high”characteristics on the distribution system in different spatial and temporal scale.Finally,the development of a“double high”distribution system is prospected.
