A transient thermodynamic model of the district heating network considering the topological structure of returning water network, the transient process of temperature variation and the time delay characteristics is proposed in this paper. The method of piecewise linearization adopted in this model not only considers the transient temperature variation for better model accuracy, but also reduces the complexity for solution through simplifying constraints of partial differential equations in the operational optimization model. The results of case study show that compared with the commonly used Time-delay model, the proposed model can lead to nonnegligible differences in the optimal solution of the operational optimization model.
