Design and Management of Hybrid Renewable Energy System

Abstract

In recent years, the interest in using renewable energy sources has been growing globally since they are considered as a key solution to satisfy the world increasing demand for energy and for reducing the global carbon emission. Palestinians have previously started utilizing solar energy for heating water for domestic and industrial uses. Recently, a strong trend has been made to use solar energy to convert it into electrical energy using solar cells. In addition, the geographic and topographic configuration and the prevalence of dominant bioenergy can be a very good potential forsmall and medium rural developments areas. This research clarified a complete design for a renewable microgrid for Al- Aroub technical College. It consists of various renewable energy systems, including the photovoltaic system, biogas as a primary energy source, a fuel cell generator and a hydrogen storage unit, which can provide electricity to developing economies. As the photoelectric generator and the methane generator provide sufficient electrical energy during the day that covers the requirements of the different loads on the farm, while the excess energy is transferred to the electrolyzer for hydrogen production and storage, and when the load needs more energy, the electric fuel cells are turned on where the hydrogen is obtained from the energy storage unit. An energy management strategy was also proposed in this study as the newly developed network control and management system, and Matlab was chosen to undertake this task. Moreover, the RETscreen Expert software that enables to determine the optimum size that meets the potential demand along with the most feasible economic values The objective of this study is to design and management of hybrid renewable energy system of Alaroub Technical collage that is located in the Hebron city which consists of 28196 kWh photovoltaic energy conversion, and 25% from load demand covered from bioenergy with Fuel cell generator and energy storage system (ESS). This study is based on identify of the optimum size that meets the possible demand along with most feasible economical values. The simulation results clearly show that the HRES consist of PV, bioenergy and small scale fuel cell generator is a more economical configuration than single renewable energy systems with battery which has a total net cost of (473570 $) , levelized cost of energy (LCOE) of (0.157) $/kWh and the lowest CO2 emission model that was( 2.1) ton per year
