International Journal of Engineering and Technology

Inherently variable nature of renewable sources of energy such as solar and wind, are incapable of meeting continuous supply demand. Combining solar photovoltaic (PV) and wind power could offer a feasible solution to the problem of continuous power supply, particularly in those geographical locations where both resources are available in abundance. The present paper investigates the solar and wind energy potential in Indian sub-continent. The feasibility of harnessing renewable energy per sq. meter of land (i.e. energy density) from a combined solar PV-Wind hybrid system in the selected location-Jaisalmer in Rajasthan, is reported. The solar irradiance and wind velocity data for the last three decades for the selected site is collected using PVsyst software. A novel design of PV-wind hybrid system is proposed to gauge the better utilization of the existing space, productivity enhancement, and energy/m2 harnessed from the utilized land. The proposed system would pave a way forward towards developing a more sustainable, effective and rugged hybrid renewable energy systems that could cater the energy needs of the Indian sub-continent and similar geographical locations. Keyword-solar energy, wind energy, renewable energy harnessing, hybrid system. I. INTRODUCTION Most of the human activities are energy dependent and therefore, it is worthwhile mentioning that energy is an inherent and the most essential part required for survival of mankind [1]. Contradictory to this, one of the most crucial challenges facing the mankind is the energy crisis [2]. Moreover, for energy needs people are still relying on continuously depleting conventional fossil fuels which emit harmful green house gases, when burnt [3]. In lieu to this, the researchers are bound to explore alternate sources of energy that are capable of meeting the continuous power supply demand, are environmental friendly, and could contribute to a sustainable society. One of the solutions to the mentioned problem is shifting to renewable sources of energy [4-6]. Most of the renewable sources of energy are inherently variable in nature and hence, is incapable of meeting the continuous power supply demand. Therefore, all renewable energy power generation/conversion systems are backed by energy storage devices such as batteries [7-9]. However, combination of more than one available renewable energy source could yield better results in terms of energy harnessing efficiency and energy production per unit space occupied. In this context, a novel design of Solar PV-wind hybrid system is proposed in which an array of solar PV is installed around the periphery of the stem of a horizontal-axis wind turbine. To investigate the feasibility of the proposed system a detailed theoretical study is conducted and simulation is carried out in PVsyst software by implementing the system on a selected site viz. Jaisalmer, Rajasthan in India. The fixed input parameters of the selected site are inserted to obtain the results in terms of power generation and its variance throughout the year.

This paper deals with the study of Wind-Solar hybrid systems in the region of Jammu and Kashmir. Due to scarcity of available less renewable energy resource in J&K region, National Institute of Wind Energy, Chennai had installed different Wind monitoring station to measure the wind data at different location. The survey reveals that four districts LEH, KARGIL, POONCH and REASI are suitable for small windsolar hybrid systems. BIDDA (REASI) and CHUSHUL (LEH) are the two sites for small wind farm development due to highest wind speed (more than 7 m/s) and power density (more than 400 W/m 2) at 100m a.g.l.

Renewable energy sources are clean sources and can meet the energy demand without causing any pollution to the environment. Wind and solar energy have good potential to replace the conventional sources, however, the stochastic behavior of both these energy sources, is a major drawback Therefore, the integration of solar and wind energy systems into a hybrid system improves the reliability, reduces the energy storage, and overcomes the over sizing problem. The main objective of this study is to utilize the available wind and solar resource to meet the energy needs of residential / institutional buildings in Western Himalayan Indian state of Himachal Pradesh. In the present study, a 6 kWp solar-wind hybrid system installed on the roof top of an institutional building is analyzed and optimized using HOMER software at different reliability levels. The total electricity production by the installed system is found to be 1996 kWh/yr with cost of energy (COE) as $1.156/kWh in which 61% contribution is from PV array and 39% from wind turbine with annual capacity shortage of 24%. The techno-economic characteristics of existing and optimum hybrid system configurations for 0%, 5%, 10 and 20% maximum capacity shortage are studied. The various optimized system configurations for this system based on the reliability are identified. The effect of maximum annual capacity on system parameters is evaluated by sensitivity analysis. A 2 kWp PV system with 1 string of 10 batteries is found to be more economical than the existing system, with COE as $0.575/kWh with 8% capacity shortage. However, in order to utilize both solar and wind resources, the optimum combination, is found to be 5kWp wind turbine, 2kWp PV system with a string of 10 batteries having COE as $ 1.051/kWh with 3.1% capacity shortage. The results of the study indicate that the solar and wind resource can be utilized economically by utilizing solar -wind hybrid energy systems for decentralized applications in the Western Himalayan complex terrain. Further research areas are also identified along with some limitations of HOMER software.

The main purpose of energy production is to fulfill the power requirements of the society along with necessary safety and reliability. The prime objective of energy generation is to satisfy customer needs economically with emphasis on safety, reliability and quality. Many conventional methods energy generation depend upon renewable and exhaustive resources like coal, oil, nuclear fuels etc. With growing environmental awareness to preserve conventional resources for future generations, escalating fuel prices, safety as in case of nuclear plants; conventional power sector has felt a setback. Ever increasing requirement of energy has led to power generation techniques stressing on reduced emissions, efficient energy uses of exhaustive sources along with safety. In the same context, technology to harness power from newer renewable energy resources has paved the way for a greener tomorrow. Worldwide interest extracting energy from Renewable Sources increasing day by day mainly because Global population has concerns over vision air quality global warming cetera electrification of rural areas developing country like India is a factor favors because these sources have minimal impact on Environment ecology and human health. Most of the people in India reside in villages and many villages are so remotely located they are not connected to any electrical power grid. Lack of power affects quality of living of such population; for example, shortage of cold storage facilities for perishable items or medicines, lack of entertainment like TV, industrial and agricultural growth etc Now renewable resources are changing this scenario. At present renewal resources have more cost of production in terms of per unit of power generation but they possess added advantage having zero and desirable impact on our environment.
