This paper thoroughly analyses energy, economic and environmental (3E) performance of using different battery (BAT) energy storage system like lead acid battery (LAB), lithium-ion battery (LIB), vanadium redox flow (VRF) battery and mechanical energy storage (MES) like flywheel and pumped hydro storage (PHS) using three different dispatch strategies (DS) such as cycle charging (CC), load following (LF) and generator order (GO), respectively. Andaman and Nicobar(A&N) Island of India have no main grid. Hybrid Optimization Model for Electric Renewable (HOMER) Pro software is used to study feasibility of power generation using various sources. Study incorporating tidal plant with wind turbine and Bio-DG in micro grid is considered first time for an Indian scenario as per authors' knowledge with application of various DS and energy storage technologies. The superiority of LIB over LAB and MES is proved in this study. Wind/Bio-DG /tidal/LIB have relatively least net present cost(NPC), cost of energy (COE) of $1.30M and $0.263, respectively among five energy storage devices using CC dispatch strategy compared to other two strategies. It is investigated that LIB uses only 250 units of batteries, which is 46% less than total utilized LAB units for catering same load. In terms of expected lifespan, energy losses, energy production and state of charge (SOC), performance of LIB are superior to LAB. SWOT and sensitivity analysis have been performed considering fuel price and wind speed. Different techno economic indicators like cost summary, cash flow, fuel summary, economics, electrical parameters, renewable fraction (RF), return of investment (ROI), lowest simple payback period, internal rate of return (IRR), pollutant emission are considered and compared with each other for LAB and LIB combinations.

An extensive canal irrigation network in South Asia has developed over the past 170 years that consists of thousands of kilometers of constructed channels and distributaries. These canals cut across many energy-poor regions along their paths. In India, this canal network provides a unique opportunity for renewable energy generation that is yet to be realized. Existing technologies for energy generation on canals include small hydropower on canal falls and, recently, canal-top solar panels. In addition, opportunities for hydrokinetic generation in irrigation canals have received limited attention. This paper develops a novel canal-network level framework for energy planning that integrates generation with local energy needs in a canal-corridor. This framework for integrated spatial assessment analyzes the supply of renewable energy generation potential and the demand of unmet energy needs in a canal-corridor, using the Upper Ganga Canal in Uttar Pradesh, India as a case study. We consider the theoretical and technological potential of hydropower and solar power generation and develop three indices to assess the agricultural, domestic, and composite unmet power demand of the canal-corridor. Our results show an overall theoretical potential of 149.1 MW and 13,213 MW for small hydropower and solar power, respectively, which could more than help meet the current 18 hours per day electricity service standard in Uttar Pradesh. The framework uses standardized irrigation and census datasets and therefore is generalizable for canal networks across India and South Asia more broadly. • Irrigation canal energy technologies include small hydro and canal-top solar power. • Novel canal-network level framework for energy planning. • Integration of generation potential with local energy needs in a canal corridor. • Theoretical and technological potential of energy generation on canals. • Three indices for agricultural, domestic, and composite unmet power demand.
