Cogeneration

CHAPTER-2 2. DISTRIBUTED GENERATION Distributed generation, also called on-site generation, dispersed generation, embedded generation, decentralized generation, decentralized energy or distributed energy generates electricity from many small energy sources. Currently, industrial countries generate most of their electricity in large centralized facilities, such as fossil fuel (coal, gas powered) nuclear or hydropower plants. These plants have excellent economies of scale, but usually transmit electricity

heating swimming pools, greenhouses, space heating and hot water systems in high rise buildings. The goal of this work is to use methane or bio-fuel from the waste treatment plant in Flint for fueling the fuel cell and the recovered heat for cogeneration. The gas separation and processing units will be powered by a high temperature fuel cell based on Molten Carbonate fuel cell (MCFC) and the heat will be used in the facilities in the waste treatment plant. This principle is energy efficient.

Inefficiencies and environmental issues associated with conventional power plants provide the drive for developments in ‘‘on-site’’ and ‘‘near-site’’ power generation. Combined, heating, and power (CHP) systems can possibly increase resource energy efficiency and reduce air pollutant emissions noticeably. CHP systems produce both electric and thermal energy, changing over 75– 80% of the fuel source into useful energy [International Energy Agency (IEA), 2008]. International Energy Agency (IEA) reported

Climate change and environmental threats came more into focus in the last years and presently they represent a large challenge for the society. This means that environmental considerations have to be integrated into a number of different decisions made by businesses, individuals, policymakers and public administrators (Finnveden et al. 2009). Environmental Systems analysis is the field that ‘attempts to find supply technology systems solutions to these challenges’ (Chalmers University, 2012) In the

generation by recovering the heat wasted during generation of electrical energy [3]. CHP economic dispatch (CHPED) aims to minimize the cost of generation of heat and power, in which mutual dependency of heat and power and heat-power capacity of the cogeneration units should be taken into account [4].

In fact, by adding a 1-megawatt CHP system, a hospital can save up to $700,000 annually through increased efficiency. Also known as cogeneration, CHP generates electricity from an on-site engine and heats and cools the hospital or medical facility using waste heat from the engine. CHP systems vary depending on the size of the hospital and its needs, but the reliability, efficiency and sustainability

Siting and operation of coal fired power plants in the U.S. today is a clear example of public and corporate policies disproportionately impacting communities of color and communities with low economic or political leverage. As discussed below, all the usual suspects associated with hazardous industrial operations make appearances. Direct toxicity, unexplained health issues, economic penalties, and failing schools (further concentration of low-income and less mobile) ravage the communities unfortunate

The Stirling engine, noted for its high efficiency, converts heat energy to mechanical work. A typical Stirling cycle consists of four phases - compressing cool gas, heating the gas, expanding the hot gas, and finally cooling the gas before repeating the cycle. The engines can run on heat from solar, geothermal, biological, nuclear sources or waste heat from industrial processes, can be built to run quietly and don’t produce any emissions. In contrast to other solutions used in solar thermal technology

1. INTRODUCTION: 1.1 Background: Reactive power in a power system is important to maintain or support the voltage to deliver the active power demanded by the load side. Synchronous generators are the main source of reactive power in most of the power plants. The reactive power capability of the generator is the amount of the reactive support produced at the rated generator terminals. The capability of these generators are represented by capability curves that are published by the manufacturer based
