Domestic demand-side response on district heating networks

The use of distributed thermal storage in district heating grids for demand side management

The work presented in this paper relates to a small scale district heating network heated by a gas fired CHP. In most common situations, such a CHP is heat driven operated, meaning that the CHP will switch on whenever heat is needed, while not taking into account the demand of electricity at that time. In this paper however, an active control strategy is developed, aiming to maximize the profit...

Valuing flexibility in demand-side response: A real options approach

The investment interests in the electricity industry are transmitted through various mechanisms to other economic activities. This paper considers methods for esteeming the adaptability of demand-side response (DSR) in its capacity to react to future uncertainties. The capacity to evaluate this adaptability is particularly critical for vitality frameworks speculations given their extensive and ...

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) ...

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...
