Abstract

In this paper, we present simulation results for a basic setup in which a photovoltaic inverter and a load are connected to a weak power distribution grid. We use both DIgSILENT PowerFactory, with a standard PV model including a reactive power controller for voltage support, and MATLAB/Simulink as simulation software. We identify conditions under which load changes result in voltage oscillations or even instability. Potential ramifications for PhotoVoltaic (PV) inverter grid codes are briefly discussed.
