Scalable Electric Power System Simulator

This paper describes concepts and design principles of a general scalable electric power system simulator (SEPSS). This tool is needed both for R&D in support of rapid modernization and as an advisory end-to-end computer application in on-line operation. The computer platform kernel is introduced using state-of-the-art modular multi-layered modeling of complex system dynamics affected by multi-temporal cyber signals (disturbances, market signals, control set points). Object-oriented MATLAB is used to represent components (actors) in detail, while their higher-level integration is done by interfacing them into clusters and ultimately into an interconnected system. The type and timing of information exchange are determined by communicating physical interaction variables among the modules without excessive complexity. We illustrate concepts in this paper on a small two control area system.
