Determining the Optimal Schedule of District Heating

Abstract

The heat demand in a given district heating system can be satisfied with discretional primary forward temperature and the appropriate primary mass flow within the limitations of the system. The task of the paper is the satisfaction of the heat demand with minimal operation cost. In the paper the objective function of control will be set up, and a method will be described that is used to define the minimum of the objective function. The minimal cost resulted primary forward temperature is the optimal primary schedule as a function of the other temperature. The secondary forward schedule plays a great part in optimal primary schedule. In the paper some results of the research with computing method will be presented.
