Selection of appropriate combination of renewable energy sources for electricity conservation by using analytical hierarchy process (AHP)

Abstract

It started with review the historical data of energy consumption which can be compiled from the electricity bills. These data are important in order to understand the patterns of energy used and their trend. After obtaining the information on energy consumption, the next step is to set up an energy audit survey. this survey gives an information on present energy used. The energy utilization such as running hours of air-conditioning, lighting levels, locations of unnecessary air-conditioning and lighting due to unoccupied areas, temperature and humidity, chillers scheduling and setting, efficiencies of equipment’s and machine and the areas of high energy consumption and the possibility to reduce consumption and renewable energy resources should be record for further analysis. In renewable energy resources we are moving toward the solar energy, wind energy and hybrid resources which can be easily installed in all the four building of whole AIKTC campus. We are going to select this resources based on their initial cost, area requirement, power generation, annual profit, maintenance cost, payback period. For selecting renewable energy resources based on those factors we are going to work with Analytical Hierarchy Process (AHP). It provides a comprehensive and rational framework for structuring a decision problem. The base of AHP is comparing variables by pair wise by Matrix relationship. In this way, pair wise of the effective variables give an alternative solution.
