Development of Renewable Energy based Hybrid System for Electricity Generation-A Case Study

Abstract: – Energy demand always lags energy supply in developing countries, which results in energy crisis. The conventional energy sources are finite and exhaustible. The solution to problem of energy crisis is utilization of renewable energy. Renewable energy sources are usually found in small scale, decentralized with regard to different geographical distribution, transition to renewable energy sources is viable option as the price of oil and gas continues to fluctuate. As an alternative to custom, onsite construction of centralized power plants, renewable systems based on PV arrays, windmills, Biofuel energy based systems or small hydropower, can be massproduced “energy appliances” capable of being manufactured at low cost and tailored to meet specific energy loads and service conditions. , to make optimum utilization of renewable energy there exists a need to integrate the different renewable energy systems. The present work involves development of Renewable Energy based hybrid system for electricity generation that can supply desired power continuously throughout the year irrespective of fluctuation of energy available from standalone systems. The energy assessment has been done using Homer simulation tool for developing small solar-wind hybrid system, performance evaluation has been done.

Key Words: Standalone systems, Hybrid Systems.

INTRODUCTION he potential of renewable energy sources is enormous as they can in principle meet many times the world’s energy demand. Renewable energy sources such as Solar PV, wind, hydropower, geothermal can provide sustainable energy services, based on the use of routinely available, indigenous resources. A small scale system and located near the consumer is called the Micro-Grid (MG) system.

The world’s energy situation, whether in developing or industrialized countries, is an issue frequently discussed under economic, technical and political aspects. While it has meanwhile become common knowledge that today’s main resources of energy such as coal, crude oil, natural gas will become scare within the next generation the renewable sources such as hydro,wind,solar and bio-energy are gaining importance in terms of research and development as well as implemented systems.
