P ower dissipation has evolved into an instrumental design optimization objective due to the growing demand for portable electronics equipment as well as due to excessive heat generation in high-performance systems. In the former case , low-power techniques are employed to prolong battery life, while in the latter case, low-power techniques are required to mitigate the reliability problems that...

This paper addresses the timely issue of modeling and analysis of custom power controllers, a new generation of power electronics-based equipment aimed at enhancing the reliability and quality of power flows in lowvoltage distribution networks .The modeling approach is graphical in nature, as opposed to mathematical models embedded in code using a high-level computer language. The well-develope...

nowadays, congestion management is one of the major tasks accomplished by system operators to warrant the operation of transmission system within operating limits. this has resulted in unanticipated congestion interfaces in regional transmission systems. the system is, however, unable to evolve at a rate which is required to meet the quickly changing demand of competitive markets. to make the m...

The power industry has relied on the same reliability concepts since 1967, including Loss of Load Probability, Component Based Failure Analysis (especially in nuclear power), N-1 (or N-2) Maximum Credible Contingency Analysis, and Generation Reserve Requirements [1] . These concepts generally involve the use of statistical engineering models for planning purposes and deterministic single (or do...

INTRODUCTION IMPROVING the efficiency of power generation equipment and ensuring its reliability are the most important factors in maintaining the reliable supply of electric power on which the infrastructure of society depends. In preparation for greater adoption of renewable energy in the future, it is also essential to establish technologies for connecting this additional generation capacity...

The multi-agent system (MAS) approach has been applied with promising results for enhancing an electric power distribution circuit, such as the Circuit of the Future as developed by Southern California Edison. These next generation power system results include better ability to reconfigure the circuit as well as the increased capability to improve the protection and enhance the reliability of t...

Renewable energy sources (RES), especially wind power plants, have high priority of promotion in the energy policies worldwide. An increasing share of RES and distributed generation (DG), should, as has been assumed, provide improvement in reliability of electricity delivery to the customers. Paper presented here concentrates on electricity storage systems technologies and applications pinpoint...

Development of distributed generations’ technology, trends in the use of these sources to improve some of the problems such as high losses, low reliability, low power quality and high costs in distributed networks. Choose the correct location to install and proper capacity of these sources, such as important things that must be considered in their use. Since distribution networks are actu...

Distribution of distributed generation resources in distribution systems has several advantages, including reducing losses, improving voltage profiles, reducing pollution, and increasing system reliability. However, one of the most important points regarding the placement of these resources in distribution networks is economic issues and the return on investment and the increase in profits from...

This paper focuses on PSS/E modeling of wind farms of Doubly-fed Induction Generator (DFIG) type and their impact on issues of power system operation. Since Wind Turbine Generators (WTG) don’t have the same characteristics as synchronous generators, the appropriate modeling of wind farms is essential for transmission system operators to analyze the best options of transmission grid reinforcemen...
