摘要

双馈风力发电机是目前的主流风力发电机,采用有功、无功解耦控制,其有功出力不受系统频率影响,无法参与系统频率的调节。风电渗透率提高带来的电网频率调节问题日益突出,风电并网标准对风电场参与系统频率调节也提出新的要求。为使风电机组表现出常规发电机组的频率调节特性,本文提出一种基于储能系统的发电机组,采用虚拟同步发电机控制策略,对风电场参与系统调频进行了研究。仿真结果表明:风电场采用虚拟同步发电机策略的储能系统能够有效支撑系统的频率,使风电场表现出常规发电机组的调频特性,改善了含有风力发电的电力系统动态频率特性。

Abstract

Doubly-fed induction generator (DFIG) is current mainstream wind power generator adopt active and reactive power decoupling control. The active power of DFIG is not affected by the system frequency, and could not participate in the system frequency regulation. The frequency regulation problem caused by wind power penetration increase is becoming more and more serious, and wind power integration standard presents a new requirement for wind farm participation in system frequency regulation. In order to make the wind power generator behave as the conventional one, this paper proposes a new wind power generator based on energy storage system, and using virtual synchronous generator control strategy to study the frequency modulation of wind farm. The simulation results show the wind farm based on energy storage system can effectively support the system frequency and performances the characteristics of conventional generator, thus improving dynamic frequency characteristics of power system containing wind power.
