考虑多种能源耦合运行方式的综合能源潮流计算方法
摘要:对于由电－气－热网络构成的综合能源系统(integrated energy system，IES)，提出了一种交替迭代求解多能潮流的新思路，以能源耦合设备的运行方式进行划分，确定不同能源子系统的计算顺序；在计算过程中保证系统网络数据与耦合设备数据的交互关系，可以让所提算法适用于多种不同的综合能源系统运行场景。最后以IEEE 33节点区域电力系统，32节点区域热力系统以及36节点的区域天然气系统共同组成的区域综合能源系统为算例，针对不同场景进行了多能潮流的仿真与分析，结果验证了所提算法的正确性与有效性。
Abstract：For the integrated energy system (IES) constituted of electricity-heat-gas networks, an alternating iterative method was proposed to solve multi-energy flow in this paper. According to the operation mode of energy coupling equipment, the calculation sequence of different energy subsystems was determined. In the process of calculation, interactions between network data and coupling equipment data can be ensured, so that the proposed algorithm can be available to a variety of different integrated energy operation scenarios. Finally, case studies were performed on IEEE 33-bus district electricity network, 32-node district heat network and 36-node district natural gas system to demonstrate the correctness and effectiveness of the proposed method.
