An equivalent simplified model for a complex heating network with a balance between solution speed and privacy
摘要
Abstract
The high dimensionality of an electric-heat energy system model will lead to great difficulty in analysis.For this reason,an equivalent simplified model of a complex heat supply pipe network is proposed,which combines solution speed and privacy.First,based on the topological characteristics of the heat network,a topological simplification method of the heat supply pipe network is proposed.It can be flexibly simplified,and an equivalent simplified model of the complex heat supply pipe network is established based on the simplified pipe structure and parameters.Secondly,a rotating standby model is established by taking into full consideration the influence of CHP units'heat-determined power mode and thermal inertia of the heat network on the rotating standby capacity.Then an electric-thermal energy system dispatching model that takes into account the equivalent simplified models of several complex heat supply pipe networks is established.Finally,the information gap decision theory(IGDT)is used to deal with the relationship between system cost and wind power uncertainty.The example results analyze the simplification effect of the heat supply pipe network topology simplification method under different degrees of simplification,and verify that the proposed model is applicable to the optimal scheduling of the electric-heat energy system.This effectively reduces the optimization model solution time.关键词
