Abstract

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.

区域多非均质能源网络的均匀流优化

目前的综合能源系统优化研究缺乏合适的统一计算模型。网络流模型具有统一表示电力系统、天然气系统和热电系统能量流分布的能力。它可以清晰地以视觉形式显示能量流。本文将异质能量统一到网络流平台进行计算。多目标综合调度优化了区域电-气-热一体化能源系统在多时段的经济效益和环境效益。仿真结果表明，该模型不受网格结构的限制，具有清晰直观的形式。算法求解速度快，保证了算法的线性收敛性。本研究可以合理考虑IES的经济性、安全性和环保性。可为多能量流多目标多周期的统一优化调度提供参考。
