A REVIEW OF INTEGRATED RENEWABLE ENERGY SYSTEM IN POWER GENERATION ROBIN THAKUR, AMAR RAJ SINGH SURI, SUSHIL KUMAR & ANIL KUMAR Department of Mechanical Engineering, Shoolini University, Solan, Himachal Pradesh, India ABSTRACT Today’s crisis in the field of energy supplies, environmental control, and population increase, poverty and shortage of food and materials are closely interrelated. Integrated Renewable energy system discussed in this paper aim at mix of possible renewable energy sources taking in to consideration sector-wise energy demand along with socio-economic and environmental aspects of energy use. Use of energy, whether renewable or non-renewable and its effect leads to different kinds of arguments in terms of its effect on environment, social cost and economic viability. Solar energy when considered on human scale is renewable and is environmentally acceptable, but its use is still in primitive stage in many parts of the country mainly because of economic barriers. Likewise, biomass energy is being used in many forms all over the world, but the most needed eco-friendly forms are still in premature stage in most of theworld. The present paper highlights the perspectives and some issues related to integrated renewable energy system. KEYWORDS: Integrated Renewable Energy, Wind Energy, Solar Energy, Power Generation INTRODUCTION Energy is a basic ingredient needed to sustain life and development. Energy is needed in various forms to fulfill our day to day requirements. Ever-increasing gap between demand and supply of energy, growing concerns about the environmental degradation associated with the use of fossil fuels and escalation cost of energy have forced the scientific community to find and develop alternate sources of energy. [1]. Renewal Energy describes energy obtained from sources, such as the sun, wind, water, and organic plant matter and geothermal, the heat found inside the Earth. Renewable sources of energy are readily available. Renewable energy is a form of energy that can be produced without depleting natural resources such has fossil fuels and wood. It does not rely on the burning of a fossil fuel to create electricity. Some forms of renewable energy include sunlight, wind, tides, water and geothermal heat. The use of biomass is also considered to be a renewable energy source. This type of energy is sustainable as it is derived from sources that do not run out. Renewable energy facilities generally require less maintenance than traditional generators. Their fuel being derived from natural and available resources reduces the costs of operation [2]. DIFFERENT INTEGRATED RENEWABLE ENERGY SYSTEMS PREVIOUS RESEARCH All countries have access to some renewable energy resources and in many parts of the world these are abundant. The characteristics of many of these resources distinguish them from fossil fuels and nuclear systems and have an impact on their integration. Some resources, such as solar, are widely distributed, whereas others, such as large hydro, are constrained by geo-graphic location and hence integration options are more centralized. Some renewable energy resources are variable and have limited predictability.
