摘要：
The combined natural gas, cooling, heating and power joint supply (CNCHP) microgrid of an industrial park has the advantages of cascaded use of energy, which can effectively improve energy efficiency and reduce pollutant emissions. In this paper, the optimal energy flow calculation model of CNCHP microgrid is established. Minimizing the total running cost of the microgrid is as the objective function, and the network operation characteristics of the cooling network, heating network, power supply network and gas supply network is considered. The model includes the loss characteristics and security operation constraints of various types of energy networks, and the obtained optimal operation schedule can meet the actual operational requirements of the microgrid. Taking a CNCHP microgrid of an industrial park as an example, the correctness and validness of the proposed optimal calculation model are verified. The results show that the optimal operation scheme of the CNCHP microgrid can effectively reduce the operating cost and improve the energy efficiency.
