TABLE OF CONTENTS In recent years, energy, environment, deregulation of power utilities have delayed the construction of both generation facilities and new transmission lines. Better utilisation of existing power system capacities by installing new FACTS-devices has become imperative. FACTS-devices are able to change, in a fast and effective way, the network parameters in order to achieve a better system performance. FACTS-devices, such as phase shifter, shunt or series compensation and the most recent developed converter-based power electronic devices, make it possible to control circuit impedance, voltage angle and power flow for optimal operation of power systems, facilitate the development of competitive electric energy markets, and stipulate the unbundling the power generation from transmission and mandate open access to transmission services, etc.
However, in contrast to the practical applications of the STATCOM, SSSC and UPFC in power systems, very few publications have been focused on the mathematical modeling of these converter based FACTS-devices in optimal power flow analysis. This chapter covers
Review of optimal power flow (OPF) solution techniques.
Introduction of OPF solution by the nonlinear interior point methods.
Mathematical modeling of FACTS-devices including STATCOM, SSSC, UPFC, IPFC, GUPFC, and VSC HVDC.
The detailed models of the multi-converter FACTS-devices GUPFC, and VSC HVDC and their implementation into the nonlinear interior point OPF.
Comparison of UPFC and VSC HVDC, and GUPFC and multiterminal VSC HVDC.
Numerical examples for demonstration of FACTS controls
The Optimal Power Flow (OPF) problem was initiated by the...
