Modelling of clustered distributed generation for economic requirements.

Abstract

In this paper,  economical and technicalconsiderations  of  distributed  generation  units  (DGU)will  be presented  in  two  steps.   The  first  one  analyseseconomic side of the distributed generation units.  Thecalculation of total cost as well as the specific generationcost will  be presented.  The last newly defined param-eter allows to compare different distributed generationunits with their own and with traditional thermal powerplants.   In  the  second  step,  the  technical  restrictionslike power stability or load flow will be considered.  Todo  this,  the  model  of  a  low  voltage  (LV)  network  hasbeen created.  The network has been divided into clus-ter, where DGU and loads are included.  The DGU willbe driven in two operating modes:  firstly variable loadaccording to the load curve and secondly with full load.Bringing  these two  models  together  the following  con-clusion will be drawn.  The use of distributed generationunits cannot be considered only from the technical pointof view.  The economic view plays also an important role.
