Secondary Switched Control With no Communications for Islanded Microgrids [PDF]
IEEE Transactions on Industrial Electronics, 2017 Flexibility and reliability of AC microgrids are enhanced by reducing the dependence on communications in multi-layer hierarchical control. In this sense, this paper presents a secondary control with no communications for islanded microgrids. It is based on a control scheme that switches between two configurations according to a time-dependent protocol.

Static Security Risk Assessment for Islanded Hybrid AC/DC Microgrid
IEEE Access, 2019 Due to the lack of the support from the main grid, the islanded hybrid ac/dc microgrid will more likely cause the power flow severe fluctuation and even the microgrid to be split once a serious contingency occurs.
