Use of Generic Dynamic Models for Photovoltaic Plants

Abstract

Electricity production using photovoltaic systems is reaching such a high level in many countries that the system operators are introducing new connection requirements. To evaluate the fulfillment of these requirements, validated simulation models are needed. These models are evolving from manufacturer’s user models to generic models as the ones proposed by the Western Electricity Coordinating Council (WECC). This paper discusses the need for generic models, introduces the photovoltaic plant model developed by WECC and presents a case of generic model parameterization, based on data from a commercial three-phase inverter, and model validation, by comparing simulation results with factory test data.
