Worldwide, due to the abrupt growth of population, load demand has been rising dramatically in last few years. This led an increase branch overloads, voltage deviations, and power losses. These problems may result line outages or occurrence blackouts. Flexible AC transmission system (FACTS) devices can be installed ensure increased flow capability flexible control address these issues. In this ...

when power systems are expanded and connected together with weak tie lines, the low-frequency oscillations are increased and the stability margin of the power system decreases. therefore, when designing the transmission system to be used, it is necessary to maintain the dynamic stability of the power system, and to make sure to have the most possible stability margin. sssc is a facts device con...

This research work presents an evolutionary algorithm namely differential evolution (DE) approach optimize location size three main types FACTS in order minimize l...

Massive growth in global electrical energy demand has necessitated a genuine exploration and integration of solar wind into the power mix. This incorporation goes long way improving cumulative generated capacity system. However, photovoltaic (PV) are intermittent nature, making provisioning good maximum tracking (MPPT) scheme necessary. Furthermore, is characterized by synchronization challenge...

Flexible alternating current transmission system (FACTS) controllers are important to enhance the quality of power in systems. The stability a is achieved via FACTS device (a Static Synchronous Compensator (STATCOM)). This paper aims control losses during peak energy demand circumstances with minimal economical and functional efficiency system. STATCOM operation seven level voltage source conve...

At the present time, FACTS technology has already been considered to bring a bright prospect for the modem power system. By the flexible and rapid control over the AC transmission parameters and network topology, FACTS can facilitate the power control, enhance the power transfer capacity, decrease line losses and generation costs, and improve the stability and security of the power system. This...

Large number of contracted power exchanges among sellers and purchasers, in a deregulated market causes transmission line congestion. Congestion lines undermines the security economy networks. Flexible AC system (FACTS) devices are introduced at appropriate spots to change flow order keep within their capability. In this work, most commonly used unified controller (UPFC) is proposed for achieve...

This paper describes a method of assessing the value of controllable devices such as Flexible AC Transmission Systems (FACTS) in a liberalized electricity market. A sophisticated algorithm using ac optimal power flow (OPF) is often unnecessarily detailed for the purpose of valuating such projects. Input parameters such as expected future generation mix is hard to guess and error prone. Therefor...

The Interline Power Flow Controller (IPFC) is a voltage source converter based Flexible AC Transmission System (FACTS) controller for series compensation and power flow management among substation's multiline transmission systems. Individual Voltage Source Converters (VSC) can inject reactive that be adjusted to manage active in line. This VSC used convert DC the kept constant entire process. I...

In the present scenario of the power system the main issue is the voltage stability enhancement which plays an important role in the complex network. This paper introduces the forthcoming technology employing the integration of Flexible AC transmission System (FACTS) device in to the system. Betwixt of all the FACTS devices this paper mainly rivet on Unified Power Flow Controller (UPFC). This i...
