摘要

随着微型燃气轮机和以其为基础的热电联供单元在配电网中的大量接入，电力系统、天然气系统和供热系统之间的耦合关系和联合优化越来越受到关注。针对电—气—热混联系统日前调度问题，建立了以系统经济成本为目标函数的日前调度模型。其次，建立了配电网、热网模型并考虑了动态特性的天然气网络模型。另外，考虑到电—气—热系统之间信息不透明特性，提出了基于改进交替方向乘子法(ADMM)，即带高斯回代ADMM的分布式优化调度方法。最后通过算例分析验证了所提模型和优化框架的有效性。

Abstract

With the more access of microturbines or combined heat and power units to distribution network

the coupling relationship and joint optimization among power systems

natural gas systems and heating systems attach more and more attention. Aiming at the day-ahead dispatch problem of integrated electricity-gas-heat system

a day-ahead dispatch model minimizing the economic cost is established. The model including the distribution network

the heat-supplying network and the natural gas network model with the consideration of the dynamic characteristics of natural gas has been established. In addition

considering the opaque characteristics of information

management

and capital between integrated electricity-gas-heat system

a day-ahead dispatch optimization method is proposed based on improved alternative direction multiplier method(ADMM)

i. e. ADMM with Gaussian back substitution algorithm. Finally

the validity of the proposed model and optimization framework is verified by case study.
