中文摘要:

为加强先进绝热压缩空气储能（Advanced Adiabatic Compressed Air Energy Storage，AA-CAES）与综合能源系统（Integrated Energy Systems，IES）的多能互补协同，提高系统运行效率，文中提出了一种含AA-CAES能源站的电-热综合能源系统优化运行方法。构建了含AA-CAES能源站的IES基本调度架构，详细分析了AA-CAES装置在压缩和膨胀工况下的储热、换热及供热等特性，建立了AA-CAES电热联供联储运行模型；基于热网管道传热延迟和损耗等动态特性，建立了考虑供热网储热惯性的热网方程；在此基础上，考虑了用户侧可调度资源，提出了计及综合需求响应的含AA-CAES能源站的IES日前优化运行模型；在修改的IEEE 33节点配电网和巴厘岛32节点区域供热网进行算例分析。仿真结果表明，所提方法可有效降低IES运行成本，提高IES可再生能源消纳能力。

英文摘要:

Integrated energy system is an effective way to achieve deep integration of multiple energy systems such as power grids, gas grids, and heating grids, and utilizes the advantages of energy coupling and interconnection to improve the energy utilization efficiency of the entire system. In order to improve the optimal operation capability of the integrated energy system, this paper firstly builds an overall model of the electricity-gas two-way coupling integrated energy system based on the power-to-gas technology and natural gas power generation technology. Furthermore, considering the characteristics of flexible and controllable topology in distribution network reconfiguration (DNR) technology, the objective function of introducing switch variables and the lowest total system operating cost in the distribution subsystem and the radial topology of the network with equal constraints, a reconfiguration model of the power distribution subsystem is established. From the perspective of reducing the complexity of solving the model, the original integrated energy distribution network reconfiguration non-convex nonlinear model is transformed into a mixed-integer second-order cone programming (MISOCP) through using the methods such as second-order cone relaxation, product variable linearization and piecewise linearization. The simulation results show that the application of power distribution network reconfiguration technology in the integrated energy system with electricity-gas two-way coupling can reduce the operating cost of the integrated energy system and effectively support the voltage of the power distribution subsystem and the air pressure of the gas distribution subsystem.
