"双高"电力系统:一种新的稳定判据和稳定性分类探讨
Power System With High Shares of Renewables and Power Electronics:A New Stability Criterion and Classification
摘要
Abstract
With the energy reform and the development of power electronics technology,the trend of high proportion of new energy and high proportion of electronic and electronic equipment("double high")in the power system is obvious,which brings new power system stability problems.This paper deeply analyzes the common instability factors and stability criteria of"double high"power systems,and explores the essential instability mechanism of system.The system impedance angular stability analysis method is proposed.Based on the proposed stability analysis method,the impedance angle stability criteria of"double high"power systems is constructed from the basic operation requirements of system active power and reactive power balance.The validity and correctness of the proposed stability criteria are verified by building a simulation model.Meanwhile,the stability classifications proposed by IEEE are further discussed.Based on the principle of maintaining the classical classification and the stability criteria constructed,a new stability classification system is proposed,which is helpful to clarify the"double high"power system stability problems and provide guidance for subsequent system planning and stability control.关键词
