Techno-Economic Optimization of Grid Connected Distributed Energy Systems using HOMER

This study presents the techno economic feasibility on grid connected distributed energy system or micro grid for a big technical institute. It is focused on how to minimize the electricity consumption from the grid by producing as much as possible renewable energy and in addition to that it integrates green vehicle transportation usage such as hydrogen gas, electric cars etc. which are necessary elements of a sustainability in the proposed system. The work is initiated collecting the institute monthly electrical load data, climate data and associated monetary data with the aim of investigating a renewable energy supply system feasibility study. Different scenarios are developed according to the project needs and the scenarios were modeled by HOMER software. The study concludes with a direct comparison of the economic feasibility, renewable energy fraction and emission among all system looks for appropriate sustainable solution. This study will provide helpful insights to the relevant stack holders and policy makers in the development of grid connected distributed energy systems.
