Study on multi-energy flow management for multi-energy network systems

Abstract

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.
