Assessment of Grid Limiting Factor to Enhance Net-Energy Metering Schemes for Industrial PV System in Bangladesh

摘要

This paper aims to address the economic feasibility of different metering schemes for grid-connected industrial PV systems in Bangladesh. An on-grid PV system is designed for an industrial load and a comparative assessment amongst net energy metering and net billing is carried out under two different scenarios – without any grid limit and with grid limit. The base case simulation was done among each case and further sensitivity analysis was performed. The metering schemes are compared based on system net present value, payback period, annual net savings for different PV installation, net energy delivered to the grid and cost analysis. Sensitivity analysis shows how grid limiting factor affects the overall PV energy scenario. Finally, the most promising tariff alternative is identified for the large-scale implementation of grid-connected industrial PV system in Bangladesh.
