| dc.description.abstract | This thesis starts by getting information from North Electrical Distribution Company (NEDCO) about all parameters and contents of the electrical network of Jenin, such as transmission lines, underground cables, transformers, loads, and PV systems in detail with all lengths, diameters, capacities, average annual consumption and PV systems power. ETAB simulator program was used to build this network, and the analysis started at a low voltage side at every load. Thesis focus on the power quality and voltage quality through the analysis. The objective of this thesis is to improve the power and voltage quality of the whole network in different ways, such as improving power factor to be more than 95% with respect to IEEE standards, improving low voltages at some loads and reducing drop voltages to be within 5% as IEEE standards, and reducing power losses using techniques such as: adding new PV systems, adding new capacitor banks, increasing the tap changers. Depending on the readings of the voltage bus and power factor (i.e., real and reactive power) of each load bus. Also, this thesis discusses another subject: the PV penetration level. It describes in detail the problem led by high penetration in the network and loads. It also discusses the solution to each problem. High PV penetration in the network causes many problems such as power losses, voltage rise, voltage fluctuations, voltage unbalance and reverse power flow that impacts the power quality; also, it causes a negative on power factor, voltage sag, harmonics, and frequency. The thesis suggests many solutions for these problems, such as: using an on load tap changer, reactive power control, energy storage system, PV generation curtailment, and smart inverter, and passive filters to reduce the harmonics effect. These solutions are described in detail in chapter 4. However, these solutions aim to balance real power and reactive power production to improve the power factor, avoid reverse power flow, store the power and use it at a suitable time and reduce harmonics effect to be within 5% for THD and less than 3% for IHD as IEEE standards.
