Modeling and Validation of Renewable Energy Sources in the OpenIPSL Modelica Library

This paper presents the implementation of industry grade renewable energy source phasor time-domain models from the Western Electricity Coordinating Council (WECC) Renewable Energy Modeling Task Force (REMTF) utilizing the OpenIPSL Modelica library. The modules described in this paper are generic, thus being able to be used to represent photovoltaic (PV), battery (BESS), and wind energy sources in transient stability scenarios, with added modularity given the object-oriented nature of Modelica models. The modeled components are briefly described, giving emphasis on how they were modeled in Modelica and coupled to the OpenIPSL library. Finally, the models described in this work were validated against the commercial software tool Siemens PTI PSS®E and showed to accurately replicate its results bringing validity to the Modelica-based implementation.
