Distributed generation optimal placement. Climatic pattern consideration

Abstract

Constant growth of distributed generation (DG) in power systems has not only positive changes. Incorrect placement of DG can worsen steady-state parameters of a power grid, for example, power losses. The specific method of optimal DG placement and capacity, that has been developed previously, was improved. Now method determines the effect of installed DG on the power grid operation considering type and capacity of DG units, climatic pattern of installation region and different power grid steady-states. Method improvements have been tested on IEEE 14-bus test system using Monte-Carlo method. The results of simulation tests show viability of the updated method.
