Stability of coupled synchronous generators

Synchronous generators are an essential component of the electric grid. Recently, the stability of the electric grid has become an area of high interest and intensive research. One reason for that is because the electric grid becomes more and more dependent on renewable energy sources.

 In the first part of this work we discuss the stability of a single generator connected to an infinite bus, and show that certain reduced models fail to predict the behavior of this system.

In the second part of this work, we investigate the stability of a microgrid composed of two identical synchronous generators, inductive lines and resistive loads. We derive sufficient conditions for local exponential stability, with a region of attraction that includes any initial state such that the states of the generators are sufficiently close to each other.
