Dynamic models of solar PV systems for use in real-time training simulators

The increasing share of solar photovoltaic (PV) generation in distribution systems urges the distribution system operators (DSO) to train their employees for secure system operation. This paper presents a simplified dynamic model of an aggregated solar PV plant which is suitable for the implementation into a real-time training simulator of the DSO. The reactive power response of the proposed model during a long-term voltage stability analysis is investigated while different voltage control strategies (VCS), reactive power limitation methods and P-Q priorities are considered. The data requirements and computation time for the simulation of the model have been minimized based on some simplifications.
