A JModelica.org Library for Power Grid Dynamic Simulation with Wind Turbine Control

Abstract

With increasing penetration of intermittent generation in power systems, it becomes essential to develop an integrated component-oriented modeling, simulation, and optimization tool for renewable energy resources to accurately capture the dynamics of large-scale power systems. Being an open, straightforward specification of differential-algebraic equations and discrete variables for component-oriented modeling and simulation of complex system, Modelica has been successfully used in robotics, automotive, aircraft, and communication systems, and is now being considered for use in electric power systems. In this paper, we show the initial efforts in the creation of OpenRES-an open-source JModelica.org library for renewable energy resources with their control blocks, and demonstrate the use of wind-farm frequency and voltage control functions in power grid dynamic simulation that is performed on the New England IEEE 39-bus test system.
