“…Besides their use for electrifying remote areas, islands, or large buildings, microgrids can be used for improving resilience to faults and power quality in power networks [3]. So far, research mainly focused on AC microgrids [1,2,3,4,5]. However, technological advances in power electronics converters have considerably facilitated the operation of DC power systems.…”

“…For AC ImGs a key issue is to guarantee voltage and frequency stability by controlling inverters interfacing energy sources with lines and loads. This problem has received great attention and several decentralized control schemes have been proposed, ranging from classic droop control [2,9], to decentralized control [10,4,5]. Some control design approaches are scalable, meaning that the design of a local controller for a DGU is not based on the knowledge of the whole ImG and the complexity of local control design is independent of the ImG size.…”

“…Some control design approaches are scalable, meaning that the design of a local controller for a DGU is not based on the knowledge of the whole ImG and the complexity of local control design is independent of the ImG size. In addition, the method proposed in [4,5] allows for the seamless plugging-in, unplugging and replacement of DGUs without spoiling ImG stability. Control design procedure with these features have been termed PnP [11,12,13,14].…”

We propose a new decentralized control scheme for DC Islanded microGrids (ImGs) composed by several Distributed Generation Units (DGUs) with a general interconnection topology. Each local controller regulates to a reference value the voltage of the Point of Common Coupling (PCC) of the corresponding DGU. Notably, off-line control design is conducted in a Plug-and-Play (PnP) fashion meaning that (i) the possibility of adding/removing a DGU without spoiling stability of the overall ImG is checked through an optimization problem; (ii) when a DGU is plugged in or out at most neighbouring DGUs have to update their controllers and (iii) the synthesis of a local controller uses only information on the corresponding DGU and lines connected to it. This guarantee total scalability of control synthesis as the ImG size grows or DGU gets replaced. Yes, under mild approximations of line dynamics, we formally guarantee stability of the overall closed-loop ImG. The performance of the proposed controllers is analyzed simulating different scenarios in PSCAD.
