Abstract
In this research, a distributed control scheme is proposed that achieves fair power sharing and weighted average voltage regulation in dynamical DC microgrids. A microgrid is considered where DGUs are connected through dynamic resistive-inductive power lines and supply so-called ZIPloads. Furthermore, every distributed generation unit is complemented with a local controller that communicates with neighboring controllers over a communication network. Achieving fair power sharing and weighted average voltage regulation reduces maintenance cost and prevents DGUs for breakdown which increases the stability and reliability of a power system. The performance of the proposed distributed control scheme is investigated via extensive simulations. Many critical scenarios are simulated, including various network topologies, failure of power and communication lines and plug-and-play of DGUs. The simulation results show promising performance of the control scheme. Fair power sharing and average voltage regulation are achieved in most of the scenarios. Besides, the results lead to interesting insights regarding the design of microgrids. Theoretical validation of the control scheme is not included in this thesis and left for further research.
