Aurora was commissioned by Power Systems Consultancy to carry out an ENA G99, Type C system study for a new 20 MW Battery Storage plant installed in Hampshire, UK. The study scope included creating a model of the local battery storage system and integrating the manufacturer inverter model and Power Park Controller (PPC) into the overall system model, before carrying out the various analysis studies such as reactive power capability, fault ride through (FRT), fast fault current injection (FFCI), voltage control and stability and frequency control.
