In a competitive power market, the task of an independent system operator (ISO) is to ensure full dispatches of the contracted power are carried out reliably. However, if it threatens the system security then ISO makes decision on the re-dispatch of the contracted power i.e., Congestion Management (CM). This paper proposes an optimal congestion management approach in a deregulated electricity m...

Recently, genetic algorithms (GA) and particle swarm optimization (PSO) technique have attracted considerable attention among various modern heuristic optimization techniques. Since the two approaches are supposed to find a solution to a given objective function but employ different strategies and computational effort, it is appropriate to compare their performance. This paper presents the appl...

Present paper proposes maiden robust coordinated design of multi-channel (P-ω-δ) power system stabilizer (MPSS) and thyristor controlled series capacitor (TCSC) based power oscillation damping (POD) controller to enhance power system dynamic stability. Introducing advanced (P-ω-δ) PSS, for the first time, in coordination with the POD controller can provide more capable structure in damping of e...

This paper presents an approach to find the optimal location of thyristor-controlled series compensators (TCSC) in a power system to improve the loadability of its lines and minimize its total loss. Also the proposed approach aims to find the optimal number of devices and their optimal ratings by using genetic algorithm (GA) with taking into consideration the thermal and voltage limits.

The power flow dynamics resulting from transmission lines charging has the potential to create nomadic congestion points, in a distribution that does not meet requirements of economic optimality. In this context, allocation Thyristor Controlled Series Compensator (TCSC) plays key role mitigating these congestions. However, number possible options for allocating compensator large porter system a...

This paper deals with the optimal location and parameters of TCSC and SVC in electrical power systems, using Particle Swarm Optimization technique (PSO). The objective is to maximize the transmission system loadability subjected to the transmission line capacity limits and specified bus voltage levels. Using the proposed method, the location of SVC and TCSC and their parameters are optimized si...

Summary Modern power networks are enormously complex and frequently interconnected by weak tie‐lines, which results in a variety of stability issues such as low frequency oscillations (LFOs). LFOs can have negative impact on system tie‐line transmission capacity, resulting catastrophic blackouts if suitable damping control mechanisms not situ. This article demonstrates robust design for inter‐a...

Series compensators have been used for many years, to increase the stability and load ability of transmission line. They compensate retarded or advanced volt drop of transmission lines by placing advanced or retarded voltage in series with them to compensate the effective reactance, which cause to increase load ability of transmission lines. In this paper, two method of fuzzy controller, based ...

This paper focuses on multi-objective designing of multi-machine Thyristor Controlled Series Compensator (TCSC) using Strength Pareto Evolutionary Algorithm (SPEA). The TCSC parameters designing problem is converted to an optimization problem with the multi-objective function including the desired damping factor and the desired damping ratio of the power system modes, which is solved by a SPEA ...
