Modelling and Optimization Of Biomass Based System In Microgrid

Abstract

The handling of biomass like MSW and rice straw becomes a challenge in the present time due to various economic and environmental challenges. Finding an economical and environmentally sustainable MSW and rice straw processing system is necessary. For hybrid power generation systems, biomass can act as a balancing system to wind and solar resources due to its different properties related to reliability. The utilization of MSW and rice straw in a microgrid system will open new doors for its sustainable processing and energy generation. This study proposes modelling and simulation of MSW and rice straw-based microgrids along with their economic and environmental evaluation. The technologies are selected after a comparative analysis of various technologies in economic and environmental terms for a particular type of biomass (MSW and rice straw). The characteristic assessment and comparative analysis of various municipal solid waste (MSW) and rice straw processing technologies are proposed to fulfill this aim. In the case of MSW, landfilling is taken as the common way to handle MSW. In contrast, the technologies such as anaerobic digestion (AD), compost, refuses derived fuel (RDF), incineration, and gasification are selected as the alternate systems to process MSW. Along with the electricity generation technologies (AD, Gasification, and incineration), other technologies such as RDF and composting are selected to compare and find the most sustainable means to process the MSW. Considering the virtual operation of the existing plants, the techno-economic and environmental parameters of all the selected technologies are assessed in the Indian scenario. For evaluation of each system, the industrial ecology-based symbiotic system approach along with Life cycle assesment (LCA) is applied to Indian MSW taking a population size of one million.
