Recently, the widespread use of power system controllers, such as PSS and FACTS controllers, has led to the analysis of their effect on the overall stability of power systems. Many studies have been conducted to allocate FACTS controllers so that they achieve optimal power flow conditions in the context of Optimal Power Flow (OPF) analysis. However, these studies usually do not examine the effe...

Multi Objective Economic dispatch (MOED) problem has gained recent attention due to the deregulation of power industry and environmental regulations. So generating utilities should optimize their emission in addition to the operating cost. In this paper a Pareto frontier Differential Evolution (PDE) technique is developed to solve MOED problem, which provides a set of feasible solutions to the ...

Following entry into the European Community in 1986, Portugal transformed rapidly its repressed banking system with deregulation, the opening of borders, the granting of new banking licenses, and privatization. In a more competitive banking system, one would expect a priori an increase in operational efficiency. This paper attempts to quantify the magnitude of efficiency gains over the years 19...

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 ...

This paper presents a fuzzy PID control including SMES for the solution Load Frequency Control (LFC) problem in a deregulated power system that operate under deregulation based on the bilateral policy scheme. The SMES units and fuzzy PID controller are expected to compensate for the sudden load change, as the most effective contermeasure. In order to overcome difficulty of accuracy constructing...

The recent increased number of black outs in the power system has been largely due to growing competition and deregulation among the power industry. Power systems are complex nonlinear systems and often exhibit low frequency electro-mechanical oscillations due to insufficient damping caused by severe operating conditions. This needs an advanced modeling and control techniques for effective cont...

The main objective of power system sustainable development is to provide the security of electricity supply required to underpin economic growth and increase the quality of living while minimizing adverse environmental impacts. New challenges such as deregulation, liberalization of energy markets, increased competition on energy markets, growing demands on security of supply, price insecurities...
