The control logic of a Microgrid (MG) represents one of the most important topic in power system engineering research. The most common and well-known control logic is represented by the droop one, that allows each MG source to share the power request and to participate to the frequency and voltage controls.

Abstract
The control logic of a Microgrid (MG) represents one of the most important topic in power system engineering research. The most common and well-known control logic is represented by the droop one, that allows each MG source to share the power request and to participate to the frequency and voltage controls. In order to reach this goal, the stability of this control logic is fundamental and it is important to understand if a determined working point can be reached. In this paper a new stability condition, based on a mathematical framework and with some simplifying assumptions is presented. The proposed approach has the advantage of being a fast calculation that can predict the reachability of a particular working point that reflects a particular load request without using numerical algorithm or software simulators. The proposed methodology is finally validated with two simulations realized on PSCAD-EMTDC.File | Dimensione | Formato | |
