Abstract

Many rural areas in the Palestinian territories (PT) continue to suffer from frequent power supply interruptions. This implements stand-alone systems as a feasible option. Better sizing of stand-alone systems increases feasibility and reduces the simple back period. Excess energy causes technical problems for the systems and reduces their feasibility. The base case is a stand-alone hybrid system that includes PV, Diesel Generator (DG), and battery energy storage system (BESS). The load is for a small residential community in Jericho, comprising 10 households. Utilizing HOMER Pro software, the optimum design was modeled and achieved. Actual solar radiation, the proposed residential load profile, and the cost of all equipment are used. The Cost of energy is USD 0.194 /kWh with contribution of RE is 92.2%. The surplus electricity is 7469 kWh/year, about 13.8%.   Different strategies and configurations are proposed to reduce and utilise the excess electrical energy produced from the base case, including the water pumping system, fuel cell (FC) system, boiler water heating system, and hybrid boiler water heating and water pumping system. The results showed the best hybrid system is PV/DG/BESS with hybrid boiler water heating and Water Pumping System. The COE is USD 0.214/kWh. The proposed system provides residential, pumping, and heating loads with minimal interruption to the power supply. This configuration enables energy management to reduce surplus electricity from 13.8% to 5.3%. Sensitivity analysis is used to study the impact and effect of varying parameters like PV cost, costs of extra equipment, and diesel fuel price.
