| Abstract (English): |
In order to realize the collaborative energy supply in the region which contains rich industrial waste heat, data center waste heat, domestic sewage waste heat and other low-grade heat sources, and improve the utilization efficiency of regional clean energy, the equipment optimal configuration strategy of regional independent micro-grid energy system is studied. Based on the temperature characteristics of various low-grade heat sources, a multi-parameter fitting model for essential heat pump equipment which can improve the temperature grade of heat sources is proposed, and the error uncertainty scenario of fitting heat pump model is generated. Considering the risk of heating comfort, load cutting and photovoltaic cutting in actual operation scenario, a two-layer capacity optimization model for independent micro-grid equipment based on conditional value at risk (CVaR) theory is proposed, in which, the upper model optimizes the equipment configuration based on the annual cost of the whole life cycle and annual CVaR value, while the lower model optimizes the operating cost based on scenario analysis. The genetic algorithm is used to solve the two-layer model. The case study results show that considering the error of heat pump model can effectively reduce the system operating risk, and the recovery and utilization of low-grade heat source has great economic potential.
