Abstract:The smart multi-energy system is considered to be the development direction of the future energy field. It is an effective model based on communication information technology, integrating multiple energy sources to improve energy efficiency and reduce energy supply costs. Electricity and thermal energy demand of the factories in the South China Modern Chinese Medicine Park are mainly met by power grid and boiler. In order to improve the comprehensive efficiency of energy in the park and promote the comprehensive use of dregs, a process of dreg gasification and biomass gas cogeneration was proposed. Further, an intelligent multi-energy system model was established with multi-objective functions and constraints for the purpose to simulate the utilization of dregs waste in the park, and it was performed by MATLAB/Simulink. Finally, the simulation results show that the total annual cost of biomass gas cogeneration decreases by 11.78% compared with the traditional energy supply mode. It is mainly reflected in the reduction of operation and maintenance costs, pollutant discharge penalty costs, and excess energy penalty costs.
