ABSTRACT
This chapter presents results of experiments to develop modeling tools with drastically improved functionality. It focuses on dynamic simulation and discusses how object-oriented and equation-based continuous-time models can be used to calculate time behavior. The Plant Modelling System Program and the Plant Design Analyser developed by the Central Electric Generating Board in the United Kingdom are other examples of tools for modeling and simulation of power systems. Object-oriented modeling and simulation are also discussed by Cellier, Zeigler, and Cutler. The chapter discusses the use of Omola models for dynamic simulation. It also focuses on continuous-time simulation and assume that behavior is described by differential-algebraic equation systems. The chapter also focuses on the simultaneous simulation approach. The OmSim environment contains a graphical model editor. It allows the user to define structured models by selecting submodels from a library menu and positioning their graphical representation with the mouse.
