SGsim: A simulation framework for smart grid applications

Simulation tools are an essential component of any emerging technology. In this paper we present SGsim, a framework to simulate different applications in the context of smart grid. The framework supports real time simulation. Therefore it is possible to evaluate time-critical applications such as real time monitoring and control. The framework combines two main simulators (1) OMNeT++, a discrete event simulator that is used mainly to simulate data communication systems and (2) OpenDSS, a tool to calculate the power flow in power grids. Moreover, the framework supports smart grid related standards such as IEEE C37.118. This way it is possible to integrate standard smart grid tools such as openPDC. Furthermore, an optimization toolbox is integrated in the simulator in addition to the capability to communicate with other tools such as MATLAB and R. We performed a set of case studies to show the capabilities of the simulator.
