Maximum power transfer capability in the transmission line is the utmost important consideration in power systems. VAR Compensator (SVC) and Static Synchronous Compensator (STATCOM) are important devices in FACTS family, and is widely recognized as an effective and economical means to solve the power system stability problem. SVC and STATCOM are used as shunt in transmission system. In the pres...

For the power quality improvement of the system FACTS devices like static synchronous compensator (STATCOM), static synchronous series compensator(SSSC), interline power flow controller (IPFC), and unified power flow controller (UPFC) etc. are introduced. These devices are used for the transmission system. But now a day’s these FACTS devices are used for distribution system and called as custom...

This paper solely discusses the voltage instability with the increment of load in a radial distribution system with Distribution Generation(DG) and compared to the system with Facts. The active and reactive power support from DG makes the system more reliable to voltage collapse. FACTS are also very good in reactive power compensator for the “sagging” voltages during the voltage collapse. The f...

Abstract The Power electronic based FACTS devices can be added to power transmission and distribution systems at strategic locations to improve system performance. This paper deals with the simulation of various FACTS controllers using simulation program with Integrated circuits Emphasis (PSPICE) .The FACTS controllers will control series impedance, shunt impedance, current, voltage and phase a...

Abstract— When measured as a commodity, electric energy can be traded in a free market, synchronized only by the bids of customers and suppliers. With the beginning of deregulation in electricity sector, many Generation and Distribution Companies have come into the picture and change the vertically integrated organization of electric utilities. However, the combined transmission system is measu...

The use of metals in the medical field has become increasingly prevalent over the past few decades. Patients find themselves being exposed to metals in a variety of ways, ranging from external exposure to instruments such as the stainless steel in surgical blades to internal exposure via medical devices being implanted in their bodies. There has been growing interest in the possibility of devel...

One of the most promising applications of the family of electronic devices called Flexible AC Transmission System (FACTS) devices is to better regulate power flow in transmission grids. In particular, the Unified Power Flow Controller (UPFC) is the best choice for complete control of power flow control. By selecting proper installation locations and control techniques, UPFCs may be able to prev...

GSA; Real power loss; Reactive power planning; FACTS; Optimization Abstract In this paper, Gravitational Search Algorithm (GSA) is used as optimization method in reactive power planning using FACTS (Flexible AC transmission system) devices. The planning problem is formulated as a single objective optimization problem where the real power loss and bus voltage deviations are minimized under diffe...
