Techno-economic assessment of microgrid in rural India considering incremental load growth over years

Abstract

<abstract> <p>India, being a developing country with a fast-growing economy, experiences ever increasing electrical energy demand. Industrial and economic development in rural India is impeded by inadequate, erratic and unreliable grid supply. This has resulted in underperformance of small-scale manufacturing and service industries. Dependency on fossil fuel-based sources as an alternative increases the operation costs and carbon emissions. Migration to cleaner energy ensures sustainable solution and addresses the issues of depleting fossil fuels, global warming and environmental hazards. In this regard, hybrid renewable energy systems have gained wide acceptance as optimum solution. Hence, authors have optimally designed hybrid energy system for power deprived rural Indian villages. Authors have heeded to the vital element of incremental load growth over years while designing the microgrid to sustain the increasing load demand of emerging economy of developing country. HOMER Pro Software is utilized to accomplish system size optimization and authors have gained comprehensive insights into techno-financial feasibility for different dispatch strategies of the proposed energy system. The levelized cost of electricity of the optimal off-grid system catering to multiyear incremental load growth is 0.14$/kWh indicating that proposed system is promising in terms of commercial efficacy. The study performs a detailed analysis of the results obtained during different phases of the project to ensure robustness and supply continuity of the proposed system. The paper also includes comparison of the carbon footprint in the proposed system with that of existing system.</p> </abstract>

Design and Techno-Economic Analysis of a Hydrogen-Based Micro Hydro-Solar Hybrid Energy System for Sustainable Energy Access: A Case Study in Sri Aman, Sarawak

“…The annual load growth should also be considered as part of an analysis to determine the long-term capabilities of the proposed stand-alone HRES. Concerning [36], the proposed growth rate for domestic users would be 5.9%. However, as the context of their study focused on a larger pool of consumers, this rate had to be lowered to fit the context of this study.…”
