  • Efficiency analysis of coal-based thermal power generation in India during post-reform era

    Coal-based thermal power stations are the leaders in electricity generation in India. This study employs the stochastic frontier production function methodology for panel data to measure the technical efficiency (TE) of coal-based thermal power plants in India during 1994-1995 to 2001-2002. Efficiency varies widely across plants and regions, while the TE is time-invariant. The average TE is ...

  • Oil shales - a competitive fuel of thermal power generation with new technologies

    We show that, in spite of the low heat of combustion of oil shales, use of them on the basis of a new thermal-processing technology that produces high-calorie products (shale tar and fuel gas) makes this type of fuel competitive for thermal power plants (TPPs) in comparison with high-calorie coals. When a certain amount of shale tar and all of the fuel gas are used in a combined cycle of a TPP, ...

  • Combined Heat and Power (CHP) essentials

    'CHP essentials' introduces the concept of power and heat 'production possibility sets', starting at the cradle of CHP, i.e., the thermal power generation plant. The latter always occasions 'fatal' heat that is either recovered (the 'merit' of CHP) or wasted (condensing). This split paves the way to defining the production possibility sets of CHP plants, shown for steam turbines, internal ...

  • Application of hybrid fuzzy PID controller for three–area power system with generation rate constraint

    This paper presents a new approach for load frequency control of three–area interconnected reheat thermal power system with the consideration of generation rate constraint (GRC). The PID–type fuzzy controller is combined with a conventional PID controller to enhance the performance and robustness of the controller. The proposed controller called hybrid fuzzy PID (HFLPID) controller has been ...

  • Power plants coordination for economic and environmental load dispatch of thermal power plants with wind generation systems

    Economic load dispatch (ELD) and economic emission dispatch (EED) have been applied to obtain generation scheduling of thermal power plants at optimum fuel cost and emissions. Due to limited availability of quality coal, issue of environmental emissions and high prices of coal, installation of renewable energy systems are suggested in power grid. Renewable energy system preferably wind generators ...

  • Aiming High Rewarding Ambition in Wind Energy - Report

    EXECUTIVE SUMMARY With 392 GW installed, wind energy can be the single largest source of power generation in the EU by 2030 ahead of coal and gas. Wind energy already plays a significant role in the European power sector. In 2014, the wind industry installed 11,791 MW in the EU - more than gas and coal combined. Today wind energy can meet 10.2% of Europe’s electricity demand ...

  • Novel cogeneration cost-sharing mechanism for energy savings and emission reduction in China

    Cogeneration can improve the efficiency of energy utilisation, improve energy savings and reduce carbon emission. However, China currently suffers unreasonable cogeneration pricing and cost sharing, which has seriously hampered the development of cogeneration power plants. Based on the production process of cogeneration, this paper analyses the principles of thermoelectric cogeneration and energy ...

  • 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 ...

  • Economics of tiny thermal power plants

    Thermal power plants is the main source of energy and electricity in India and almost all countries of the world. Most of the giant thermal power plants have capacity of 500MW to 1000 MW. Investment in such giant thermal power plants is Rs 100 million per MW including transmission lines and distribution lines. ( 60 rupees = 1 US$, MW=1000KW). So 1000MW thermal power plant costs Rs 100 million/MW ...
