Abstract

Abstract: An evaluation criterion of micro grid is proposed from the perspective of economy, energy conservation and emission reduction. The heterogeneous energy such as cold, heat and electricity based on the micro grid taking combined cooling heating and power as the core was evaluated based on the energy value through the cascade utilization of energy, and the micro-grid optimization model including the micro-turbine, waste heat boiler, lithium bromide absorption chiller, fan and photovoltaic was established. As compared with the model of cost optimization only, its integrated optimization index increased by 11.547% and the efficiency of exergy increased by 14.651%.
