Operation Condition Emulation Method for Grid-Connection Testing of Grid-Forming Photovoltaic Inverters
摘要
Abstract
Grid-forming control technology provides an effective solution for improving the dynamic stability of power grids by simulating the inertia characteristics of synchronous machines through converter control systems.In photovoltaic inverters,the inertia simulation is achieved by controlling the DC voltage and utilizing the energy stored in the DC capacitor.Conventional grid simulators often focus on AC-side grid characteristics ignoring the impact of the DC-side power source for photovoltaic inverters,which makes it unable to meet the testing requirements for AC-DC coordinated control strategies of grid forming photovoltaic inverters.An innovative scheme for an AC-DC dual-port operating condition simulation test platform is proposed.By synchronously simulating the AC-side grid voltage,frequency and impedance characteristics,as well as the DC-side photovoltaic power generation dynamic characteristics,a full-condition simulation method for grid-connected testing of grid-forming photovoltaic inverters is constructed.关键词
