Energy delivery at well construction in regions with hard climate is distinguished by variable demand in electric and heat power. Energy consumption of drilling equipment, production and living facilities varies greatly during the year, depending on power load charts and climate conditions. Power supply of remote well construction sites is mostly accomplished by operating autonomous power sourc...

Electric locomotive is a kind of high power rectifier load, and its load characteristics will have a significant impact to safe, stable and economic operation of power system. This paper mainly analyses load characteristics of harmonic and reactive power for electric locomotive. Simulation model of electric locomotive is set up based on time trigger; it is so better conform to the dynamic chara...

The growth in demand for electric power and the rapid increase in fuel costs, in whole of theworld need to discover new energy resources for electricity production. Among of the nonconventionalresources, wind and solar energy, is known as the most promising deviceselectricity production in the future. In this thesis, we study follows to long-term generationscheduling of power systems in the pre...

In this paper, we develop a static electric power supply chain network equilibrium model with known demands and establish the equivalence between the model and a transportation network equilibrium model with fixed demands over an appropriately constructed supernetwork. This equivalence yields a new interpretation of electric power supply chain network equilibria in path flows. We then exploit t...

Regional transmission organizations, state utility regulatory commissions, the North American Electric Reliability Council, regional reliability councils, and increasingly, the Federal Energy Regulatory Commission all advocate, call for, or in some instances, require that electric utilities and competitive power suppliers not only have enough generating capacity to meet customer demand but also...

With wider deployment of the plug-in electric vehicle (PEV), a power distribution network operator (DNO) would expect increasing domestic demand due to large numbers of vehicles charging. This could lead potentially to overloading of power system assets unless appropriate demand side management is in place. The UK coalition government has made a commitment to increase the amount of renewable ge...

The rich countries of Western Europe and its citizens benefited during at least the last 30 years from an extraordinary stable electricity grid. This stability was achieved by the european grid system and a large flexible and reliable spare power plant capacity. This system allowed a continuous demand growth during the past 10-20 years of up to a few % per year. However, partially due to this o...

C ONSUMERS are expected to play an increasingly important role in current electricity markets through smart grid systems , where risk and uncertainty are becoming central issues. The availability of an advanced metering infrastructure provides one of the building blocks for bi-directional communications between consumers and suppliers, creating an opportunity for large-scale load control within...

The main purpose of this study is to give support irrigation in dry season and reduce the gap between electric power demand and generation by using renewable energy source solar pump. Every year water level is going down 2m/year. As a result scarcity of ground water is increasing, which has a harmful effect on economy. On the other side, electric power demand is growing up for commercial, indus...

The unit commitment problem is a typical scheduling problem in an electric power system. The problem is determining the schedules for power generating units and the generating level of each unit. The decisions concern which units to commit during each time period and at what level to generate power to meet the electricity demand. In this paper we develop a stochastic programming model which inc...
