The main objective of flexible AC transmission systems (FACTS) controllers is to improve system stability: transient, voltage, and small‐signal, such that the AC transmission system becomes more reliable or additional power flow can be transferred on critical paths. This chapter discusses the use of FACTS controllers to accomplish these goals. It focuses on series compensation with fixed series capacitors and thyristor‐controlled series compensators for improving power system transfer capability and stability. The chapter describes FACTS based on both the thyristor and voltage‐sourced converter technologies. It also discusses the static var compensator (SVC) steady‐state operation, in which the SVC would regulate its terminal voltage precisely to a desired value in negligible time. The chapter describes the use of controllers based on a voltage‐sourced converter technology for AC‐DC conversion, allowing them to perform both reactive and active power control. It considers shunt controllers and series and coupled controllers.

This chapter discusses the power flow formulation and solution process. It discusses calculating transmission‐line active and reactive power flow between the buses, setting up the admittance matrix of a power network, formulating the power flow problem, and the Newton‐Raphson algorithm for solving nonlinear power flow equations. The chapter also discusses more advanced topics on using sparse factorization to minimize the storage and computation effort of the Newton‐Raphson method, and performing powerflow for multiple power control regions with specified interface flows, which is commonly known as multi‐area power flow. It provides the power flow formulation of the steady‐state operation of a power system and its solution using the Newton‐Raphson method. The chapter describes advanced features such as multi‐area power flow and tie‐line flow control as well as computational savings from decoupled power flow and sparse factorization.

This chapter focuses to develop positive‐sequence synchronous machine models suitable for dynamic simulation of power system disturbances. A synchronous machine subject to a 3‐phase fault exhibits a variety of time responses in different time scales, namely, the transient and subtransient effects, as it settles to a new steady state after the fault is cleared. The chapter discusses how to interface the detailed synchronous machine model to the power network, and how to develop a linearized synchronous machine model. The generator terminal voltages are developed using the states from the synchronous machine dynamic model. The linearization of power systems with subtransient generator models will increase the dimensions of the state variables and the system matrix. The chapter shows the systematic reduction of the 2‐axis model to simpler models, including the flux‐decay model and the electromechanical model. It should be noted that finite‐element methods have been proposed to compute the machine parameters.
