含光伏-储能的并网虚拟同步发电机协调控制策略
Coordinated Control Strategy of Grid-connected Virtual Synchronous Generator with Photovoltaic and Energy Storage
摘要
Abstract
Virtual synchronous generator (VSG) technology is a novel control method, which can simulate virtual inertia for distributed generator, and solve the problem of power system stability caused by large-scale grid-connected renewable energy sources.However, existing researches only focused on the control of inverter interface of VSG, which ignore the analysis and control of DC side components.Therefore, distributed generator and energy storage devices are modeled, and coordinated control of VSG and DC components is achieved by energy management.A coordinated control strategy is designed for grid-connected VSG with photovoltaic and energy storage, which alleviate the impact on power grid caused by the sudden change of PV output to compensate unbalanced power rapidly and adjust the charge state of energy storage equipment.Relevant theoretical analysis and proposed scheme are verified by the simulation system built with Matlab/Simulink simulation tool.关键词
