Multiple FACTS devices integration through distributed control system and its application on the GCC interconnection

Abstract

Principal aim of this work is to present a HVDC/FACTS control devices implementation framework for multipurpose on the GCC (Qatar, KSA, Oman, Bahrain, Kuwait and UAE) power grid. This framework architecture encompassed of five layers of FACTS control devices (STATCOM, SSSC, and UPFC). This five-layer architecture is designed for its future growth and reusability so that more complex GCC power system problems are addressed within control architecture. This five layers framework-architecture named “FACTS-FRAME” which demonstrates how various FACTS devices are communicating to each other and controlling at different location on the GCC power grid in order to address complex power system issues which are persisting. The FACTS-FRAME is designed to handle and implement distributed control system which has the capability to control and adjust the devices operations as per needs. Based on distributed control the FACTS-FRAME has the capacity and capability to address poor voltage quality, poor load flow control, limited power transfer capacity and power system stability issues through parallel operations of various FACTS devices at different location on the GCC power grid. In order to prove and implement FACTS-FRAME method, numerous mathematical models are derived by considering current operational and safety scenarios to indentify and determine errors between the models how these are communicating to each other for control purposes. Distributed power flow algorithms are also developed in order to understand and implement FACTS devices as appropriate. Conclusively, very much promising results are obtained by establishing integrated multiple FACTS devices “FACTS-FRAME' network on the GCC power grid.
