- ItemTechno-Economic Analysis and Energy Management of Installation onGrid PV Systems “An-Najah National Hospital as Case Study’’(2016) Ahmad Yousef Khaled Khlouf; Dr. Imad IbrikThis thesis analyzes the performance of implementation of on-grid PV systems and energy management system in Palestine, from thetechnical and financial point of view. Also the design and simulation of a 104kWp grid connected PV system and a Demand Side Management (DSM) system for An-Najah National Hospital and summarizes its performance results using PVsyst computer software. The simulation results were positive as the peak demand was reduced from 240kW to 160kW for building This PV system and DSM system is comprised of the following components. An array consist of PV modules produced from apolycrystalline solar cell of 330W, making up a total peak power of 104 kW. In addition, there are five dual mode inverters of 20kW and an energy storage system of 68 kWh which used in energy management and shortages cases. The system will produce about 187000kWh per year. From economical viewpoint PV systems and DSM systems have high initial cost which was about 187000$, but the economic evaluation of the system shows that unit cost of the system was about 0.19$/kWh and 0.15$/kWh for PV system with DSM and for PV system without DSM which was less than from energy cost from NEDCO which selling energy to consumer by 0.21$/kWh this means the unit cost is acceptable in both cases and makes annual saving about 40000$ in electrical energy bills. In the economic evaluation the Rate of Return (ROR) method and Simple Payback Period SPBP was considered and the ROR was about 23% and the SPBP was 7 years including battery replacement cost and these results show that the system has high revenues and profit for the lifetime, in other words, the project is highly feasible.
