Centralized control of district heating networks during failure events using discrete adjoint sensitivities

Numerical modelling of district heating networks

Efficient Physical Modelling of District Heating Networks

A mathematical physical model for dynamic simulation of flow and temperature in district heating networks (DHN) is proposed. The network structure is described by means of a graph-theoretical approach where the network elements are pipe sections, consumers and heat sources. The governing equations for hydraulic flows and heat distribution through pipe networks are presented. In addition, proper...

Thermo - hydraulic simulation of district heating networks

Current developments of the European energy markets are influencing the operation strategy of heat suppliers. Especially providers of district heating systems fed by conventional heat production (i.e. CHP) have to react with appropriate measures to these changes. The integration of thermal storages, decentralization of the heat production, changing heating technologies or adjusting the temperat...

District Heating Networks Calculation and Optimization

The first step in studying the behavior of a pipe network is to identify the objectives that must be attained and the physical and logical problems that must be solved; this aim can be achieved by building a suitable model of the network. The next step must be the operation of the model (which, for example, in the case of numerical models consists of using an appropriate algorithmic procedure) ...
