Voltage Profile Improvement in a Renewable Energy Based Hybrid Distribution System
J. Environ. Nanotechnol., Volume 13, No 2 (July 2024) pp. 80-87
Abstract
The integration of high photovoltaic (PV) and wind penetration into distribution networks is an important strategy for improving voltage performance while supporting cleaner and more sustainable electricity generation. This study evaluates a 33 kV, 14-bus distribution feeder to assess the influence of distributed generation (DG) on voltage regulation, reactive power management and network performance using ETAP software. The proposed hybrid configuration combines PV panels, wind turbines and strategically placed capacitors to address reactive power demand and reduce distribution losses. Particular attention is given to the voltage profile and power factor under the proposed renewable-energy configuration. The Adaptive Newton-Raphson method is employed to provide an efficient load-flow assessment of the distribution system. The study demonstrates how renewable distributed generation can contribute to improved power quality and more efficient utilization of distribution infrastructure. The findings also indicate opportunities for future integration of nano-enabled photovoltaic materials, nanostructured energy-storage components and advanced smart-grid technologies to further enhance renewable-energy conversion, environmental sustainability and grid performance. The framework therefore offers an environmentally relevant basis for future nano-enhanced renewable power conversion, storage and sensing in intelligent distribution networks and microgrids.
