Over the course of the 20th century, the electrical power systems of industrialized economies have become one of the most complex systems created by mankind. In the same period, electricity made a transition from a novelty, to a convenience, to an advantage, and finally to an absolute necessity. World-wide electricity use has been ever-growing. The electricity infrastructure consists of two hig...

abstract: the main goal of this paper is to modeling of producers’ strategic suggestions for each electricity manufacturer in an oligopolistic structure. according to the proposed structure of the electricity market modeling; this paper uses a dynamic model based on cournot equilibrium. due to the large volume of required information, the implementation of the model is limited to a regional ele...

Combined cooling, heating, and power (CCHP) systems produce electricity, cooling, and heat due to their high efficiency and low emission. These systems have been widely applied in various building types, such as offices, hotels, hospitals and malls. In this paper, an economic and technical analysis to determine the size and operation of the required gas engine for specific electricity, cooling, ...

E lectricity has particular importance in the national economy and providing socio-economic welfare. It is considered an essential infrastructure of the countries development. This is why the management of electricity consumption and the formulation of proper policies for it is very important for policy-makers. To do this successfully, it is necessary to identify energy consumption p...

An important application of computers from the 1950s and onwards has been for designing and operating complex infrastructural systems like air traffic, telephony, railways, and electricity. This paper tells the story about how computers from the 1950s and onwards became an important tool for designing and operating the Swedish power grid. It describes two phases of this development. In the 1950...

The combined generation of electricity by wind and solar energy is a very attractive solution for isolated regions with high levels of yearly wind energy and insolation. A computer model is developed for the simulation of the electricity system of a Mediterranean island, including a wind power plant, a photovoltaic power plant and a storage system. In order to obtain an overall view of the syst...

existed electricity grids deliver produced power to the consumer passing through transmission and distribution grids. according to high losses of these grids in transmission level and inexistence of bilateral interaction for simultaneous information exchange, a concept of smart grids were made by capabilities such as consciously participation of consumers in the smart electricity grids, an amou...

In actual electricity market, which operates repeatedly on the basis of one hour or half hour, each firm might learn or estimate other competitors’ strategic behaviors from available historical market operation data, and rationally aims at its maximum profit in the repeated biddings. A conjectural variation based learning method is proposed in this paper for generation firm to improve its strat...
