Present-day world energy policy is based on two main
directions: energy efficiency and environmental
protection. Efficient Combined Heat and Power
production is one of the energy consumption effective
methods, where CHP production from the renewable
fuels is preferable. [1]
In order to plan for the most economical, technical and
environmental optimal CHP system, it is especially
important to estimate the expected heat demands and heat
load profiles for the district heating area.
This paper describes a method for estimation of heat load
profile for a given district heating area by dividing it to
three different heat load types:
Temperature depended heat load;
Constant heat load;
User defined heat load.
The paper provides a complete description of above
mentioned heat load types, equations as well as
calculation examples. Calculation results are compared to
hourly measured heat loads to estimate accuracy of a
proposed model.
