Abstract
In this manuscript, a hybrid wind/solar/battery energy system is proposed for a stand-alone applications. Wind-solar energy sources are used as power generation source in the proposed hybrid energy system (HES), whereas battery is used as energy storing system in order to manage the power flow among various power generation sources and energy storing system. Power management control strategy is also presented for a suggested hybrid system. Through the real load demand and practical weather data (proposed area is Jamshoro, Sindh Pakistan), the system performance is verified under different situations. It is observed that the hybrid system produces maximum power in summer season as compared to other seasons throughout the year. Moreover, the power generated from wind and solar energy contributes 77.88% and 22.12%, respectively. However, it is clearly observed that the HES is cost effective and can be used in remotely rural areas which are isolated from power grid. In future work, the HES can be integrated with the power grid in order to meet the load demand during shortage of power.
Highlights
The growing energy utilization, expanding environmental contamination, high rate and the prompt decline of fossil fuels have made increasing concern towards renewable energy generation sources, i.e., wind energy, solar energy, geothermal, biomass, and tidal energy [1]-[5, [18]
Renewable wind and solar resources are utilized as major energy sources, whereas battery is used as storage device
While during the deficiencies of www.ijacsa.thesai.org (IJACSA) International Journal of Advanced Computer Science and Applications, Vol 9, No 6, 2018 power generated from wind and solar energy system due to weather issues, the battery backup will supply the power to meet load demand
Summary
The growing energy utilization, expanding environmental contamination, high rate and the prompt decline of fossil fuels have made increasing concern towards renewable energy generation sources, i.e., wind energy, solar energy, geothermal, biomass, and tidal energy [1]-[5, [18]. In Pakistan, the renewable energy sources have a huge potential to produce electric power and these resources can play a vital role in overcoming energy crisis [6], [7]. The wind and solar energy are abundantly available, free, inexhaustible, and have no emission of greenhouse gases, they are atmosphere friendly [3], [5], [6], [10] Due to such features, these renewable energy resources can be utilized on large scale to produce power in order to meet load requirement [6]. Wind and solar energy resources have their own deficiencies, such as wind is not accessible at all times and solar is accessible only day time, in order to make sure the continuity of power supply to meet the load requirements, it is essential to make wind and solar energy resources along with storage device as a hybrid energy system [9].
