  • Evils for giant power houses

    Giant Electricity Power Houses such as giant thermal power plants or giant nuclear power plants are established  either by governments by collecting tax from the people or by giant private companies by collecting huge money by way of shares of the company. In either cases, money comes from the people.   Giant  Electricity Power Houses give rise to giant ...

  • A genetic algorithm to solve the thermal unit commitment problem

    In this paper, a genetic algorithm (GA) is proposed to solve the thermal unit commitment (UC) problem. The objective of UC is to determine the optimal generation of the committed units to meet the load demand and spinning reserve at each time interval, such that the overall cost of generation is minimised, while satisfying different operational constraints. The results obtained show that, with ...

  • Green Futures Rely on Strong Magnets

    When lodestone was first discovered before the 1800s people were amazed at this rock that got attracted to itself. They noticed that it pointed to a specific direction every time it was suspended freely or was placed on water. This led to its use in the first compass to give sailors direction as they went for expeditions at sea. Further investigations led to the production of stronger ...

  • Near Term Lower Cost Solar Electric Power for US Commercial Customers

    Market Opportunities The first market for PV electric power panels was for space satellites. While the single crystal cells used in these panels made these panels very expensive, this was unimportant for that market. That market emphasized reliability, not cost. As these panels came down to earth for off-grid remote applications, again the emphasis was on reliability and low maintenance, not ...

  • Economic Potential for Thermophotovoltaic Electric Power Generation in the Steel Industry

    ABSTRACT - A steel mill extrudes steel billets at temperatures above 1400 °C continuously 24 hours a day. The steel billets then go to cooling beds where they slowly cool down to below 1100 °C. JX Crystals Inc makes Gallium Antimonide (GaSb) thermophotoyoltaic (TPV) cells that can generate over 1 W/cm when exposed to infrared radiant energy from glowing steel at temperatures above 1100 ...

  • Evaluating the effect of resource constraints on resilience of bulk power system with an electric power restoration model

    Although reliability standards for electric power systems are well accepted, methods and metrics are not established for evaluating the effects of large–scale disruptions that exceed N − 1 criteria for bulk power systems. This paper introduces a model for simulating restoration of bulk power systems following such disruptions. The model allows analysts to simulate disruption of a bulk power ...

  • Experimental design approach to explore suitability of PI and SMC concepts for power electronic product development

    Power electronics equipment is deployed for control of power flow in electrical domain. Steady and fast growth in controller, active and passive power and control components, power control topologies etc. and the impact on overall gains it makes to society have led the evolution process of power electronics field to mature fast. Apparently, contemporary SMC concepts with their simple ...

  • Water sustainability decision-making for electric utilities case study

    The electric power generation sector uses approximately 41% of all freshwater withdrawn in the United States—more than any other water use sector. The Electric Power Research Institute (EPRI) conducts research and development to help address challenges in electricity generation, delivery, and use, including water sustainability issues. On behalf of EPRI, LimnoTech conducted research and is ...

  • A practical transmission loss allocation methodology for deregulated power systems

    In any power network, the cost of electrical losses constitutes a large component of network operating costs. As a result of introduction of competition under deregulation, it has become much more important to be able to determine a strategy for fair allocation of losses among the stakeholders. This paper suggests a quadratic loss formula with nodal power injections as independent variables. The ...

  • Analysis of a PM DC motor model for application in feedback design for electric-powered mobility vehicles

    Accurate modelling of Permanent Magnet (PM) DC motors is a prerequisite for expedient feedback design of electric-powered mobility vehicles. This paper identifies the parameters in the ideal equations for PM DC motors and considers the methods used to measure and calculate them accurately. However, the ideal PM DC motor equations' outcomes are rarely accurate compared with the actual results and ...
