摘要
综合能源系统(integrated energy systems,IES)近年来在世界范围内得到广泛关注。基于电力系统分析综合程序(power system analysis software package,PSASP)的图模一体化平台,开展了IES仿真系统的研究,功能包含生产模拟分析、能量流稳态计算和动态仿真。生产模拟采用混合整数线性优化(mixed integer linear programming,MILP)方法,对包含传统电力、风电和光伏可再生能源、天然气、热力、储能等的IES实现多阶段优化分析。IES稳态能量流计算采用电-气-热能源子系统交替顺序求解方式实现,天然气、热力流体网络采用回路方程形式。以天然气为例,对回路法进行了分析,给出了IES稳态能量流分析的计算流程。对生产模拟、稳态能量流计算和动态仿真的一些关键技术环节进行了分析。
Integrated energy systems(IES) attract increasing attention worldwide in recent years. Their simulation system is based on unified graphics and data platform of PSASP. The main functions of the simulation system are presented, including production simulation, steady-state and transient analysis of IES. The production simulation uses multi-stage mixed integer linearization optimization(MILP), including conventional generation, renewable energy sources(RES), gas, heat, energy storage, etc. The steady state energy flows in respective networks(electricity, gas, and heat) are solved in sequence. The models of pipe networks(e.g., gas and heat pipelines) are based on loop equations. The flowchart of energy flows analysis is proposed. The key technologies of IES simulation for production simulation, steady-state and transient analysis are presented.
