| description | This research investigates the impact of integrating photovoltaic (PV) systems into power grids to address voltage instability and efficiency issues caused by load imbalances. This study employed the Newton-Raphson power flow solution algorithm to analyze the power flow problem, strategically placing PV units using a new voltage stability pointer (NVSP), and determining optimal PV unit sizes derived from the exact power loss formula. The study also assesses frequency stability post-PV integration utilizing the IEEE 14-bus test system as a reference on ETAP 19.0 and MATLAB R2018a. The NVSP analysis identified buses 9, 14, 13, 12, and 11 as suitable locations for PV integration. Optimal PV unit sizes for these buses were determined. After PV integration, there was a notable improvement in voltage profiles, with bus 14 experiencing a 3% voltage magnitude increase. Voltage magnitudes at other buses also fell within an acceptable range (1.007 to 1.110 p.u.), enhancing the overall network voltage profile. Moreover, active and reactive power losses significantly decreased, resulting in a 62.86% reduction in active power losses and a 67.40% reduction in reactive power losses, leading to improved network performance. However, some cases of frequency deviation, especially at PV buses, were observed. In conclusion, PV integration holds great potential for enhancing power grid performance by improving voltage profiles and reducing power losses. |
