Power System Modeling, Simulation, and Control Design

This chapter provides a basic conceptual guide to power system modeling, simulation, and control design, illustrating the ideas through application on an example test system. A power system is a large-scale complex network of components spread over a wide geographical region. Hence, building its physical prototype is prohibitive, and modeling and simulation have been the common practice for studying its operation and behavior. The chapter begins with a discussion of dynamics of power system components, which are primarily responsible for influencing the overall system dynamics and used to build their dynamic models. Next, the overall dynamic behavior of the power system is analyzed through simulations of the integrated model. The chapter concludes with a discussion about the basics of control design frameworks for designing an economic, practical, and efficient methodology for controlling the system's oscillatory dynamics.
