In order to remain competitive in a deregulated environment, a group of European Utilities developed a prototype of a single Marketplace called e-utilities•com whose mandate is a clear customer centric orientation in the European environment for a successful mid-term multi-utility business via the Web. This paper highlights the concept of e-utilities•com and its implementation in a Web portal.

This paper presents the particle swarm optimization (PSO) technique to optimize the integral controller gains for the automatic generation control (AGC) of the interconnected power system before and after deregulation. Each control area includes the dynamics of thermal systems. The AGC in conventional power system is studied by giving step load perturbation (SLP) in either area. The AGC in dere...

This paper presents the modelling and simulation of Static Synchronous Series Compensator (SSSC) in a two area system for Automatic Generation Control (AGC) under deregulated environment. The modelling of Thyristor Controlled phase Shifter (TCPS) is also carried out and comparison is made between SSSC and TCPS. A two area hydrothermal system under deregulated environment has been considered for...

This paper presents a new simplified AGC model for deregulated power systems. New AGC model facilitates us to design the controller without considering bilateral contracts. And also concentrates only the load disturbances not on the contracted loads. New AGC in deregulated power system is modeled by modifying conventional model with inclusion of bilateral contracts. Bilateral contracts will all...

The battle for electricity customers in an increasingly competitive and deregulated market environment is one of the challenges facing the electric power utilities of today. Customers expect a reliable and efficient supply of power from their utilities. One of the advantages that a distributed generator (DG) can provide to the electric utility and to customers is the possibility of improving th...

A Firefly Algorithm (FA) based on Fuzzy PID controller is proposed in this paper to solve the Load Frequency Control (LFC) problem in a deregulated environment. In multi area electric power systems, if a large load is suddenly connected (or disconnected) to the system, or if a generating unit is suddenly disconnected by the protection equipment, there will be a long-term distortion in the power...

Abstract Deregulation in power system and increased demand has introduced congestion system. With the depletion of fossil fuels, sector turned towards incorporation Renewable Energy Systems through private generators. This paper focuses on non-cost-free method to mitigate by rescheduling generators for their active output. The is done such a way that cost minimum. presents new merge two tested ...

Voltage stability is an important issue in the planning and operation of deregulated power systems. The voltage stability problems is a most challenging one for the system operators in deregulated power systems because of the intense use of transmission line capabilities and poor regulation in market environment. This article addresses the congestion management problem avoiding offline transmis...

This paper implements a power flow application and variations using the IEEE Power System Application Data Dictionary within a Matlab environment. It describes a number of useful data and implementation techniques for a variety of applications. The techniques include the use of very compact and efficient code for the computation of Power Transfer Distribution Factors. Power Transfer Distributio...
