ENHANCEMENT OF VOLTAGE PROFILE AND MINIMIZATION OF LOSS USING INTEGRATED DISTRIBUTED GENERATION

Growing electricity demand and the push for clean energy have led to greater use of distributed generation (DG) in modern distribution systems. This paper investigates the influence of three DG technologies such as diesel engines, wind power, and solar photovoltaic system to improve voltage regulation and minimize losses in the IEEE 33-bus network. The analysis employs MATLAB-based simulations to assess changes in network performance stemming from DG integration. The study applies particle swarm optimization (PSO) to determine the most effective DG with its sizes and locations, Emphasizes that accurately positioned DG units can strengthen voltage stability and minimize system losses. In addition, suboptimal DG placement will result in voltage anomalies and higher losses, reinforcing the importance of careful DG planning within the distribution grids. The results obtained for with DG and without DG enhancement in voltage profile and loss minimization were compared with the existing results and is encouraging. The findings with the successful incorporation of renewable technologies towards improved stability and reliability of grid is very supportive.
