Modeling of the solar panel diesel-generator system stability

摘要

The question of studying the distributed generation systems stability is relevant due to several factors. These are: the constant load level and environment change and, accordingly, the change of generators parameters that make up this system. In the article, the stability of distributed generation system consisting of the two generators, one of which operates a current source mode is considered. First generator is the solar panel with MPPT device and the second generator is the diesel-generator with output voltage regulation via fuel supply and field winding current control channels. Analytical expressions and C++ application for the stability calculation, as well as the mathematical model of the system in Matlab Simulink with load magnitude change are given.
