ABSTRACT

Methods of constructing equivalents of electric networks of 110...220 kV in order to determine the change of power and energy losses on condition of integration of the sources of distributed generation have been proposed and tested. The mathematical apparatus of the experimental design was used to solve this problem. Evaluation trials were analyzed for the obtained models to determine their usability in computer experiments under the lack of feasibility of duplicate tests.
The authors have obtained results destined for complex estimation of the effect of the sources of distributed generation connected to electrical network in different points.

KEYWORDS

factorial design of experiments, electrical networks, distributed generation, power and energy losses.
