The thesis proposes a controller that enables microgrids to have a modular structure, to be flexible in terms of linked energy consumers and resources, and to offer the possibility of prioritized demand side management, while avoiding the need of employing a dedicated communication network. For this, the control strategy applies droop control, combined with a variable frequency setpoint depending on the state of the grid. Furthermore, a strategy for applying demand and supply side management is established, enabling the grid to operate stable using renewable energy resources. The reactions of the proposed control structure have been studied in a broad range of cases, using simulations performed in DIgSILENT PowerFactory. Results show that the proposed controller has a satisfactory performance, it is able to interface multiple microgrids without the necessity of dedicated communication, and both load shedding and renewable energy curtailment schemes can be initialized, when needed.
