Optimization of a Stand-Alone Hybrid Renewable Energy System Using Demand-Side Management for a Remote Rural Area in India

Abstract

AbstractIn this study, a techno-economic feasibility analysis of a stand-alone hybrid renewable energy system (HRES) for a remote rural area of Chikmagalur district of Karnataka (India) has been presented. Load shifting-based demand-side management (DSM) has been implemented for Lead-Acid and Lithium-Ion batteries based HRES for evaluating the feasibility. The performance of the proposed system has been conducted with DSM and without DSM. From the results, it is found that Lithium-Ion battery-based HRES with DSM gives the optimal feasible solution for providing reliable power supply to the proposed un-electrified villages. The optimal Net present Cost (NPC) and Cost of Energy (COE) are found to be $467,644 and 0.106 $/kWh without DSM implementation. Whereas, the operating costs are $314,564 and 0.072 $/kWh respectively with DSM implementation. Based on the analysis, it is observed that the saving of NPC and COE is found to be $153,080 and 0.034 $/kWh, respectively.KeywordsHybrid renewable energy systemDemand-side managementLead-AcidLithium-IonHOMER
