The Improving Control System of Distributed Generation Sources Taking into Account Their Dynamic Parameters

Abstract

Today rapid growth of distributed generation can cause some problems that related with power system stability. The mathematical models and algorithms are playing a major part in evolution of electronic systems. Therefore, the improving of models and algorithms is fundamental problem in further systems development. The algorithm for information support an automated system has been studied. The inertia constant, which representing dynamic property of electric generator, has been founded by analyzing components of mathematical model, describing dynamics of power system. It should not be forgotten, however, that the most of the distributed generation control systems have focus on power control (P and Q) to achieve reliable operation of the local grid. The suggestions about supplementing control system algorithm of power system with distributed generation sources for concern of their dynamic properties are made. The supplementing consists of including information-feedback system (IFS) module on all hierarchical levels. This module includes data and algorithm of analyzing the stability. The structure of module and database are developed.
