Abstract
Hybrid energy system (HES) is a combination of different renewable resources such as wind, solar, biomass, small/micro hydro, with fossil fuel powered diesel generator to provide electric power. This paper gives the design idea of optimized Hybrid Energy System for a certain technical college over a conventional diesel generator for a particular site in eastern India (Kolkata). For this hybrid system ,the meteorological data of Solar Insolation, hourly wind speed, are taken for Kolkata-Eastern India (Longitude 88°22’and Latitude 22°34’) and the pattern of load consumption of technical college are studied and suitably modelled for optimization of the hybrid energy system using HOMER software. This paper gives the detail hypothetical study for standalone hybrid energy system for technical institute in five stages: (a) recent electric bill of the college for the year 2011. (b) Studying the load demand for every month in a year. (c) Calculating the maximum, minimum and the average load demand. (d) Introducing the solar data in HOMER software. (e) Designing the hybrid model. This system is more cost effective and environmental friendly over the conventional diesel generator. It should reduced approximate 70% - 80% fuel cost over conventional diesel generator and also reduced the emission of CO2 and other harmful gasses in environments. The action plan is formed on the basis of cost effective modelling that is minimization of energy production cost in a long run.
Highlights
Energy is vital for sustaining life on earth
For the analysis of this hybrid system we have considered four sensitivity variables
An optimal system is defined as a solution for hybrid system configuration that is capable of meeting the load demand of the technical institute
Summary
Energy is vital for sustaining life on earth. It is needed to improve the quality of life by exploiting the natural resources. The energy problem is synonymous to ecological and economical problems. The world energy demand has been increasing. The convention energy resources are exhaustible and limited in supply [1]. There is an urgent need to conserve these resources and explore the wider use of alternative energy resources for example —solar, wind, hydro, biomass, etc. The hybrid energy system (HES) [2], has received much attention over the past decades. It is viable alternative solution [3] as compared to system which relies entirely on hydrocarbon fuel
