摘要：

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. © 2019 Automation of Electric Power Systems Press.
