Research on wind storage control technology supporting wind power active frequency regulation capability
摘要
随着风电渗透率不断提高,电力系统等效转动惯量持续下降,频率稳定面临严峻挑战。为此,该文以双馈风机(double fed induction generator,DFIG)与电池储能系统为研究对象,基于不同风速下DFIG参与调频的能力,提出一种风储协同参与电网一次调频控制策略。所提策略针对风速、频率变化率设计模糊逻辑控制器,实现DFIG的新型虚拟惯量综合控制,可在惯性响应阶段利用有限的风机转子动能抑制频率快速跌落;同时基于电池储能的荷电状态(state of charge,SOC)设计自适应控制逻辑,在DFIG逐步退出调频的过程中让储能系统平滑接替出力,并且维持频率的稳态恢复过程。最后,对所提风储协同调频策略进行仿真验证,结果表明,所提策略能够在不同风况下有效改善系统频率响应特性,实现风储调频功率的合理分配,可避免发生频率二次跌落,保障高比例风电并网场景下的系统频率稳定性。
Abstract
With the continuous increase in wind power penetration
the equivalent rotational inertia of power systems keeps decreasing
and frequency stability is facing severe challenges. Therefore
this paper takes the doubly fed induction generator (DFIG) and battery energy storage system as research objects
and proposes a wind-storage coordinated control strategy for grid primary frequency regulation based on the frequency regulation capability of DFIG under different wind speeds. The proposed strategy develops a fuzzy logic controller considering wind speed and rate of frequency change to realize a novel integrated virtual inertia control for DFIG
which can suppress the rapid frequency drop during the inertial response phase by utilizing the limited rotor kinetic energy of the wind turbine. Meanwhile
an adaptive control logic is designed based on the state of charge (SOC) of the battery energy storage system
enabling the energy storage system to smoothly take over power output as DFIG gradually exits frequency regulation and maintain the steady-state frequency recovery process. Finally
simulation verification is performed on the proposed wind-storage coordinated frequency regulation strategy
and the results show that the proposed strategy can effectively improve system frequency response characteristics under different wind conditions
achieve rational allocation of wind-storage frequency regulation power
avoid the occurrence of secondary frequency drop
and ensure system frequency stability in scenarios with high-proportion wind power integration.
