Environmental and financial impact assessment of off-grid microgrids with energy storage and PV
27th International Conference on Electricity Distribution (CIRED 2023)(2023)
摘要
This paper investigates the environmental and financial effects of adding solar PV and storage to off-grid microgrids to reduce or remove diesel usage. A simulation study including a Life Cycle Analysis (LCA) and a financial model is presented for a military base use case. Hereby three scenarios are investigated; a baseline with only diesel usage (I), a number of diesel reduction scenarios (II) and a diesel removal scenario (III). The results show that in Scenario II a 24-30% diesel reduction can be achieved, leading to a 22-27% kg CO2 eq. per kWh reduction and a 23-27% cost reduction in respect to Scenario I. Scenario III shows that a complete diesel removal is possible leading to a 75% kg CO2 eq. per kWh reduction and a 43-68% cost reduction.
