Abstract: A novel energy targeting framework is proposed to analyse an urban-industrial symbiosis (UIS) system by incorporating Heat Integration, Power Integration, heat storage, power storage, renewable energy sources, and waste heat cogeneration. A trigeneration power plant is incorporated into the framework to connect the multi-energy microgrid. The trigeneration system provides high operational flexibility of the UIS through the manipulation of system outputs. This framework can handle multiple heating and cooling grids, which have different temperatures. An illustrative case study is also developed to demonstrate the proposed Pinch-based multi-energy targeting framework. The energy requirement of the heating-cooling-power microgrid in the UIS is successfully targeted. With the flexible trigeneration load estimated based on the thermal energy requirement of the UIS, the case study shows 34% of energy-saving opportunities and a payback period within a year. The case study suggests that the constant load operation can reduce the design capacity of the trigeneration system; however, the energy loss in the energy storage increases the utility cost and causes the system less attractive.
