电力电子接口对电力系统频率控制的影响综述
The Impact of Power Electronics Interfaces on Power System Frequency Control: A Review
摘要
Abstract
Devices such as wind turbines,solar power,and flexible high voltage direct current (HVDC) transmission are connected into power system via voltage or current source converters,which bring changes to system frequency dynamics,power balance principle and control methods.Recent frequency events are reviewed first.Then impacts on system frequency control of large-scale power electronic interface are analyzed in aspect of system inertia.Interface control technology that is engaged in improving frequency support capability are summarized,and degree of equivalence of external characteristics between electronic interface and synchronous generators are analyzed based on inertia response and primary frequency control.Power frequency balance based on law of conservation and conversion of energy in power system with large-scale electronic interfaces are discussed.Finally,some questions worthy of exploration in terms of principles,models and methods are proposed.关键词
