考虑一致性二阶项的含多VSG微电网功频振荡抑制策略
Power frequency oscillation suppression strategy for microgrid with multiple VSG considering consistent second order terms
摘要
Abstract
Distributed generation(DG)in microgrid is generally connected through power electronic converter interface,which reduces the inertia of microgrid.The virtual synchronous generator(VSG)can provide inertia support for the microgrid.However,due to the incon-sistent response speed to load changes,power frequency oscillation will occur between multiple DGs using VSG,and even cause the insta-bility of the microgrid.To solve the above problems,a power frequency oscillation suppression strategy for microgrid with multiple VSGs is proposed considering the consistent second-order term.Firstly,the secondary control strategy of microgrid with multiple VSGs based on first-order consistency is established,and the mechanism of power oscillation between multiple VSGs is studied by using small signal anal-ysis method.Then,the second-order term of consistency is introduced to provide damping for power frequency oscillation,and the adaptive gradient algorithm is used to optimize the second-order control coefficient to improve the suppression effect.Finally,the feasibility of the strategy is verified by a simulation example.关键词
