Networked control approach for distributed generation systems

Microgrid has emerged as an answer to growing demand for distributed generation ( DG ) in power systems. It contains several DG units including microalternator, photovoltaic system and wind generation. It turns out that sustained operation relies on the stability of these constituent systems. In this paper, a microgrid consisting of microalternator and photovoltaic system is modeled as a networked control system of systems ( SoS ) subjected to packet dropouts and delays. Next, an observer-based controller is designed to stabilize the system in presence of the aforementioned communication constraints and simulation results are provided to support the control design methodology.
