Homogeneous Flow Optimization in Regional Multi-Heterogeneous Energy Networks

Current research on integrated energy system (IES) optimization lacks a suitable unified calculation model. The network flow model has the ability to uniformly represent the energy flow distribution of the electric power system, natural gas system and heat power system. It can clearly show the energy flow in a visual form. In this paper, the heterogeneous energy is unified to the network flow platform for calculation. Multi-objective comprehensive dispatch optimizes the economic and environmental benefits of regional electric-gas-heat integrated energy system under multi-period. Simulation results prove that the model is not restricted by the grid structure and has a clear and intuitive form. The corresponding algorithm is solved quickly and linear convergence is guaranteed. This study can reasonably consider the economy, safety and environmental protection of IES. It can provide a reference for multi-energy flow multi-objective multi-period unified optimization dispatch.
