Multi-energy coupling hub is the core component of micro-energy network
so the accuracy of its system model has an effect on the operation efficiency of the micro-energy network. Aiming at the multi-energy coupling hub which consists of solar power and wind power generation systems
energy storage systems
organic Rankine cycle(ORC)systems and combined cooling
heating and power(CCHP)systems
this paper develops a multi-objective optimization model for multi-energy coupling in the micro-energy network. The optimization model considers the load demand
the price factor and the environment
and it aims to minimize the system operation costs
primary energy consumption and carbon emissions. The particle swarm optimization(PSO)algorithm is used to solve the operation strategies of the generator and the energy storage system
and the optimal target is obtained. Finally
the advantages of the multi-energy coupling system in energy efficiency and carbon emissions are verified by comparing it with the microgrid.
