The applications of wind energy develops much more rapidly than the other renewable resources such as solar, geothermal etc. in the 21st century. It becomes the third core energy resource following non conventional fuels as oil and chemical. Electrical energy generated by wind power plants is the fastest developing and most promising renewable energy source. The wind is a clean, free and inexhaustible...
Large capacity Turbo Generator (TG) in conventional power plants is meant for base load operation. Continuous operation of TG sets is inevitable to meet the load demands. The Stator core of the large TG comprises a cylinder of laminated steel sheets supported by Key Bars and Core end plates. Abnormal operation of the machine like over voltage and under frequency constitutes in over fluxing. This phenomenon...
In this study, Biogeography Based Optimization (BBO) algorithm is developed for the prediction of the optimal sizing coefficient of Small Autonomous Hybrid Power System (SAHPS) in remote areas. BBO algorithm is used to evaluate optimal component sizing and operational strategy by minimizing the total cost of SAHPS, while guaranteeing the availability of energy. Due to the complexity of the SAHPS design...
In order to evaluate the techno-economic performance of Hybrid Energy System for remote rural area electrification, a mixed integer linear mathematical programming model (time-series) has been developed to determine the optimal operation, optimal configuration including the assessment of the economic penetration levels of photovoltaic array area, and cost optimization for a hybrid energy generation...
Hybrid energy systems (HES), which utilize different renewable resources such as wind, solar, biomass, small/micro hydro, with fossil fuel powered diesel/petrol generator to provide electric power, are well suited for remote rural areas. This paper presents a general methodological framework for the formulation of an action plan for the small-scale hybrid energy system for remote area. The action...
This paper presents the results of the application of model (developed in Part-I) and simulation algorithm (developed in Part-II) for determining the techno-economics of battery storage type hybrid energy system intended to supply the load demand of a rural remote area having a cluster of nine villages (grid isolated). The hour-by-hour simulation model is intended to simulate a typical one month period...
A well designed hybrid energy system can be cost effective, has a high reliability and can improve the quality of life in remote rural areas. The economic constraints can be met, if these systems are fundamentally well designed, use appropriate technology and make use effective dispatch control techniques. The first part of this tri-series paper, presents the analysis and design of a mixed integer...
Computer simulation is an increasingly popular tool for determining the most suitable hybrid energy system type, design and control for an isolated community or a cluster of villages. This paper presents the development of the optimum control algorithm based on combined dispatch strategies, to achieve the optimal cost of battery incorporated hybrid energy system for electricity generation, during...
Exergy analysis of a 500 MWe steam turbine cycle is performed to identify the components that offer significant work potential saving opportunity. Criteria of performance relevant to the individual components are formulated. Exergy flows, exergy consumption due to irreversibilities and rational performance parameters for the turbine cycle and its components are computed by using plant operation data...
