Multi Objective Operation Optimization of Distributed Integrated Energy Microgrid with CCHP Considering Heating Pipeline Network Characteristics

Distributed integrated energy microgrid has typical characteristics of multi-energy coupling of cooling/heating/electricity/gas. How to optimize the operation of combined cooling, heating and power and a variety of energy storage equipment has been one of the key and difficult research work at this stage. This paper establishes heating pipeline network model, based on the balance equation constraints of electricity/cooling/heating and flue gas waste heat utilization, the upper and lower limits of the system equipment. And by configuring the weight coefficient, the total operation cost and the total CO

emissions in an operation cycle are the comprehensive operation optimization goal. A typical scenario of a university town was constructed, the influence of pipeline network characteristics on the optimization of distributed energy microgrid operation was analyzed.
