Shrnutí:Remote locations often face an acute power shortage due to poor connectivity with the grid or intermittent power supply from the utility. To mitigate this challenge, this paper proposes a multi-energy system-based community microgrid, which consists of various electrical and thermal generation units, thereby allowing localized generation-load matching. In particular, the selected community microgrid system consists distributed energy resources such as solar PV system, battery energy storage system, and a biomass gasifier for power production. On the other hand, high power-consuming loads such as cold storage, a flour mill, critical, and domestic loads within a village are also modeled and included, through actual surveying in a rural location in India. Further, using these demand and generation inputs, the optimal dispatch schedule for the proposed multi-energy system is obtained by solving a mixed integer non-linear programming problem. It is shown that the proposed multi-energy system can meet the demand of the village cost-effectively, subject to the operational constraints of all appliances and generators. Additionally, based on the economic analysis of the system, this paper also develops a self-sustainability plan for the microgrid operation for the socio-economic welfare of the community.
