Abstract
Recognizing the importance of electricity as a driver of rapid economic growth and poverty alleviation, India aims to provide access to all households by 2030. Despite the best efforts of state and federal governments to meet consumers’ electrical needs, budget constraints, inefficient operations and massive loan burdens have hampered their efforts. Aside from these concerns, rural India, which accounts for 65% of the population, is plagued by a slew of issues, including low electricity demand, a low load factor and the expectation of cheap electricity. These concerns bind the authorities’ hands, preventing them from moving forward. As a result, this project aims to model an autonomous microgrid system that integrates three potential renewable-energy systems, namely wind, sun and hydrokinetic, to provide electricity for a remote society. It starts with assessing the region’s electricity needs with its inhabitants. The HOMER Pro platform creates a cost-effective microgrid based on the demand estimate. The components of the microgrid include 6.4-kW small wind turbine (SWT) groups, 4.4-kW solar photovoltaic (PV) panels, a 5-kW hydrokinetic water turbine, battery storage and a converter. The project is unique in that it considers site-specific initial capital costs, replacement costs, and operation and maintenance costs of the renewable-energy systems, and it does not include any environmentally hazardous energy system. The successful optimization results in terms of levelized energy costs are $0.0538, $0.0614 and $0.0427/kWh for wind, solar and hydrokinetic components, respectively, without any environmental issues.
