摘要：
We propose a decentralized control synthesis procedure for stabilizing voltage and frequency in AC Islanded microGrids (ImGs), i.e. electrical networks composed of interconnected Distributed Generation Units (DGUs), power lines and loads. The presented approach enables Plug-and-Play (PnP) operations, meaning that DGUs can be arbitrarily added or removed without compromising the overall ImG stability. The main feature of our approach is that, differently from (Riverso et al., 2015), the proposed PnP design algorithm is line-independent. This implies that (i) the synthesis of each local controller does not require anymore the model of power lines connecting neighboring DGUs, and (ii) whenever a new DGU is plugged-in, DGUs physically connected to it do not have to retune their regulators. Theoretical results are validated by simulating in PSCAD the behavior of a 10-DGUs ImG. (C) 2017, IFAC (International Federation of Automatic Control) Hosting by Elsevier Ltd. All rights reserved.
