The　famous　virtual　synchronous　generator　technique　greatly　improves　the　inertia　responses　of　system　with　high　penetration　ratio　of　renewable　energy　sources.　However,　the　power　oscillation　phenomena　resulting　from　the　swing　equation　indicates　the　possibility　to　overload　the　virtual　synchronous　generators-controlled　inverters.　To　tackle　this　issue,　this　paper　proposes　a　power　oscillation　damping　method,　where　the　frequency　dynamic　is　feedforward　as　a　compensating　signal　into　the　voltage　reference.　This　method　is　proved　to　be　equivalent　to　the　traditional　velocity　feedback　method　used　in　servo　systems　for　improving　the　system　damping　characteristics.　The　proposed　method　can　not　only　suppress　the　power　oscillation　but　have　no　influence　the　steady-state　operating　point　of　virtual　synchronous　generators　control.　The　effectiveness　of　the　proposed　method　is　preliminarily　verified　by　simulation　and　hardware　experiments.　©　2022　IEEJ-IAS.
