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...

The interconnection of transmission, distribution, and generation lines has established a structure for the power system that is intricate. Uncertainties in active flow are caused by changes load growing dependence on renewable energy sources. study presented this paper employs several controlling strategies to reduce frequency variations series-compensated two-area systems. Future systems will...

This paper proposes a novel online measurement-based Wide-Area Voltage Control (WAVC) method using Phasor Measurement Unit (PMU) data in power systems with Flexible AC Transmission System (FACTS) devices. As opposed to previous WAVC methods, the proposed does not require any model knowledge or participation of all buses and considers both active reactive perturbations. Specifically, exploits re...

-In this paper, multi-objective optimal placement (MOOP) of multi-type flexible AC transmission systems (FACTS) devices for Thailand power system is proposed. Four types of FACTS devices are used: thyristor-controlled series capacitor (TCSC), thyristor-controlled phase shifter (TCPS), unified power flow controller (UPFC), and static var compensator (SVC). The problem is decomposed into the opti...

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...

The increasing complexity of the conventional grid due to population growth, advancement in technology, and infrastructures are the factors that contribute immensely to instability, insecurity, and inefficiency of the use of electrical energy. To overcome the problems, the environmental energy sustainability calls for the use of renewable energy for sustainability of power supply. Intermittency...

The Static Var Compensator (SVC) and the Static Synchronous Compensator (STATCOM), as two components of Flexible AC Transmission System (FACTS) devices, play an important role in controlling the reactive power flow to the power network. Because of economic considerations, identifying the best location for installing the SVC and STATCOM is also important. The FACTS devices placement problem is c...
