In this paper we explain how to design intelligent agents able to process the information acquired from interaction with a system to learn a good control policy and show how the methodology can be applied to control some devices aimed to damp electrical power oscillations. The control problem is formalized as a discrete-time optimal control problem and the information acquired from interaction ...

This paper presents the use of Flexible AC Transmission Systems (FACTS) for improving loadability of the system in deregulated electric power system.The optimallocation and parameter settingsof two types of FACTS devices have been investigated in this study. The Static Synchronous Series Compensator (SSSC) and Thyristor Controlled Series Compensation (TCSC) as two FACTS devices are considered i...

In this paper, a hybrid Tabu Search and Simulated Annealing (TS/SA) approach is proposed to find the optimal placement of multi-type FACTS devices to simultaneously minimise the total generator fuel cost and violation function. The problem is decomposed into the Multi-Objective Optimal Placement (MOOP) of multi-type FACTS devices subproblem that is searched by the hybrid TS/SA approach and the ...

Voltage collapse; Sequential quadratic programming; FACTS devices; Voltage security margin; Optimal continuous power flow. Abstract In this paper, an effective method is presented to determine the security margin against voltage collapse, and improve it by means of FACTS devices in the optimal continuous power flow framework. The primary methods for determining the system’s critical states of v...

This paper describes a new stochastic heuristic algorithm in engineering problem optimization especially in power system applications. An improved particle swarm optimization (PSO) called adaptive particle swarm optimization (APSO), mixed with simulated annealing (SA), is introduced and referred to as APSO-SA. This algorithm uses a novel PSO algorithm (APSO) to increase the convergence rate and...

Over the years, Nigerian power system is beset with lingering problems, which include severe losses, as well very low transfer capability of transmission network to evacuate from generating stations load at distribution level. Presently, industry undergoing restructuring, especially in generation and systems. In view deregulation electricity marketing, traditional practices are changes address ...

Topology for reactive power compensation of dynamic load in closed loop is presented. The scheme consists of Thyristor Binary Switched Capacitor (TBSC) banks and a Thyristor Controlled Reactor (TCR). TBSC is based on a chain of Thyristor Switched Capacitor (TSC) banks arranged in binary sequential manner. TCR capacity is chosen to be smallest of TBSC step size. A transient free switching of TBS...
