Parallel Simulation of Power Systems with High Penetration of Distributed Generation Using GPUs and OpenCL

In this paper, we present the use of parallel-in-space simulation approach to accelerate the dynamic simulation of power systems with high penetration of distributed generation, i. e. high number of power electronic devices. The approach is implemented using the OpenCL framework and executed on a graphic processing unit (GPU). We benchmark our prototype implementation using a distribution network with increasing number of distributed generator which is modeled by voltage source inverter. Results show that the computation time for the distributed generators solution stays nearly constant with the increasing number of the distributed generators in the network.
