SGSim: A unified smart grid simulator

Abstract

SGSim is a unified simulator to enable development and evaluation of new operation algorithms and technologies for smart grids. SGSim provides full-scale distribution side virtual environment that smart grid is pursuing by combining power flow and communication altogether. Essential elements such as customers, intelligent electronic devices, and renewable resources, are designed as agent models and they interact and communicate with each other or with operation systems. In addition, to consider the regional characteristics of renewable generations weather simulation is combined. It has a multi-agent and multi-platform architecture for scalability and flexibility. With the simulation system, unexpected impact hidden behind complex correlations and influence propagation for specific events can be easily monitored and evaluated.
