TABLE OF CONTENTS This chapter discusses the recent developments in modeling of multi-functional single converter FACTS-devices in power flow analysis. The objectives of this chapter are:
to model the well-recognized FACTS devices such as STATOM, SVC, SSSC and TCSC in power flow analysis,
to establish multi-control functional models of these FACTS-devices,
to handle various internal and external operating constraints of FACTS-devices.
It is well known that power flow calculations are the most frequently performed routine power network calculations, which can be used in power system planning, operational planning, and operation/control. It is also considered as the fundamental of power system network calculations. The calculations are required for the analysis of steady-state as well as dynamic performance of power systems.
In the past, various power flow solution methods such as impedance matrix methods, Newton-Raphson methods, decoupled Newton power flow methods, etc have been proposed [1] [13]. Among the power flow methods proposed, the Newton's methods using sparse matrix elimination techniques [14] have been considered as the most efficient power flow solution techniques for large-scale power system analysis. A detailed review of power flow methods can be found in [1]. In this chapter, FACTS models for power flow analysis as well as the implementation of these models in Newton power flow will be discussed in detail.
In power flow analysis, all buses can be classified into the following categories:
Slack bus. At a slack bus, the voltage angle and magnitude are specified...
