OPTIMAL OPERATION OF A DISTRIBUTION SYSTEM SUPPLYING A BUILDING WITH RENEWABLE ENERGY RESOURCES.

For domestic consumers in rural areas, the source of electrical supply is diesel generators which emit carbon dioxide resulting in environmental pollution and it is costly too. Therefore, in present scenario, the need of an hour is to improve and provide efficient energy supply for rural areas. Hybrid Smart grid is a power system with distributed resources serving the whole community as an independent electrical island with the bulk power system. The aim of this paper is to simulate and do the mathematical modeling of each component and optimizing using HOMER (Hybrid Optimization Model for Electrical Renewable) Software in order to determine the economic feasibility of hybrid grid to ensure reliable power supply to load demand and minimization of cost. In this paper, in first case photovoltaic system, wind turbine, converter are taken with storage battery & diesel generator for backup and have been simulated and optimized for library in College of Engineering and Technology, MUST at, Lakshmangarh , Rajasthan 332311 , India. In second case, the system includes solar panel, battery, generator, converter and loads. In this study we calculate overall load in library. After knowing overall loads result for this library we simulate this data through HOMER tool and we compare the results of first and second case which is presented in this paper. The goal is to maximize energy output with least cost of energy from distributed energy resources (DERs) by optimization using HOMER. Performance of each component of model will be evaluated and sensitivity analysis will be performed to optimize the system at different conditions.
