In many countries, the farmers find open burning is the cheapest and easiest way for removing large loads of the produced rice straw causing environmental pollution. So, finding a sustainable rice straw management system is need of the hour. In modern hybrid electricity generation systems, the use of rice straw on priority is not evaluated yet. To satisfy this need, this article proposes conceptualization and techno-economic evaluation of a small-scale rice straw based microgrid that processes the surplus rice straw of a village having 250 houses and 900 acres of cultivated land for power generation. The system is capable to process the 1128 tonne/year of ¹surplus rice straw and meet the electrical load demand of the same village. The gasification technique is used to process the rice straw, which is further integrated with solar, battery and the utility grid. The optimum size of the microgrid is found using artificial bee colony algorithm. The economic evaluation of the proposed microgrid is organized on the basis of net present cost, annualized system cost and levelized cost of electricity (LCOE). The LCOE of the proposed system is found to be acceptable which is 6.70 INR/kWh (0.089 $/kWh).
