dc.description.abstractThis study investigates the technical and economic impacts of integrating energy storage systems into grid-connected PV systems using the electrical network of Jenin's Arraba village as a case study. Four different configurations of PV and sizes of energy storage systems are compared to assessing their impact on the most critical grid performance parameters, including voltage regulation, energy loss reduction, and dynamic load control. Utilizing ETAP for simulation, the study also analyzes actual grid behavior under real conditions, harmonic distortion due to the PV inverter, and reverse power flow when there is high PV penetration. Harmonic distortion was found to be moderate in Case 0 and increases notably in Cases 1 and 3, with the highest distortion observed at low-voltage buses in Case 3. Reverse power flow was observed in Case 3 with negligible export to the upstream grid, highlighting the importance of control mechanisms at high penetration levels. Economic efficiency is assessed considering the System Advisor Model with high focus on main indicators like payback period, net present value, and levelized cost of energy. Among the four cases, Case 1 is the most efficient cost-saving setting with the smallest levelized cost of energy of 17.4 cents/kWh and a payback period of 8.2 years. While having superior technical performance in Case 2 and Case 3, their increased investment cost reduces their economic efficiency. The conclusion is that Case 1 has the optimal trade-off between technical effectiveness and economic viability, and it is an acceptable solution for grid stability, power quality management, and peak-shaving in small- to medium-size applications. The report wraps up by recommending longer-term investigation of hybrid energy storage technology, predictive algorithms, and long-term service reliability of energy storage under the conditions of diverse grids.
