Abstract

A method for energy flow optimization in a multi-energy system based on spatiotemporal network flows is disclosed. The multi-energy system includes M energy storage devices, photovoltaic power generators and N micro gas turbines (MGTs). The method includes: obtaining an objective function of the network flows in the multi-energy system; determining constraints of the network flows, where the constraints include a power balance constraint, an energy storage period constraint, an energy storage capacity constraint, an energy storage charging and discharging constraint, a generator power constraint, and an energy storage charge quantity constraint; establishing a network flow model with the objective function and constraints; solving the network flow model with a shortest-path and max-flow algorithm, to obtain an optimal power flow (OPF) in the multi-energy system; operating the multi-energy system by adjusting parameters of the energy storage devices and the MGTs based on the OPF.
