Solar air heaters of many types have been developed in India and their performance studied in detail. The application of these air heaters are limited to a few demonstration projects for food dehydration, and space heating. Some of these case studies are described in this paper. For a few cash...

We examine load-frequency control of isolated WDMHPS provided with conventional proportional-plus-integral controllers. The parameters of the controller are optimised for system performance with step or realistic disturbances using an integral-square-error (ISE) criterion. Non-optimum gain...

A simple linear model has been developed to minimize the cost function for an energy-supply system consisting of a mix of energy sources and conversion devices. The model has been applied to a typical village in India for both the domestic and irrigation sectors. The energy-demand assessment was...

Performance equations of the HWB type have been derived for a closed-loop water-heating system using a solar air collector. Explicit expressions are given for the collector efficiency and overall heat-loss coefficient. The utility of the performance equations has been established with the help...

Due to the growing energy needs along with increasing concerns towards control of greenhouse gas emissions, most developing countries are under pressure to find alternative methods for energy conversion and policies to make these technologies economically viable. Most of the energy is produced...

India will require increasingly higher energy inputs for future industrial and economic development. Overall growth of energy consumption will result in substantially higher emissions of CO2. We present emission rates of CO2 based on India's actual fuel consumption. It is estimated that use of...

The present gap between demand and supply of electricity in India may grow up to 70% in the year 2045, if corrective measures are not taken immediately. The projected situation for the growing Indian economy needs to be tackled by measures to reduce demand as well as to explore additional energy...

In a renewable energy-based system, energy storage must match the energy demand with supply. Usually a lead-acid battery is utilised as a short-term energy buffer. A system, which has a combination of an electrolyser and a high-pressure hydrogen tank for long-term energy storage, is considered...
