摘要：Multi-energy network system which brings together electricity, heat and gas is one main
feature of energy Internet. It not only promotes the full utilization of distributed
renewable energies, but also enables users to participate in the operation of the system
much widely and deeply. This will change the modes of energy utilization and promote
the revolution of energy production and consumption. Aiming at multi-energy flow
management in the multi-energy network systems, first, a mathematical model of the
power, heat, and natural gas multi-energy system has been established. And then based
on the feature of energy routers, a multi-energy flow management model is established.
As the core equipment of the energy Internet, energy routers can adjust and optimize the
flow of multi-energy and transmit real-time information. Finally, with a test system, the
results based on ITLBO (improved teaching-learning based optimization) show that the
management of multi-energy flow is feasible and efficient.
