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.

Optimal Bidding of a Microgrid Based on Probabilistic Analysis of Island Operation
Energies, 2016 Island operation of a microgrid increases operation survivability and reliability when there is a large accident in a main grid. However, because a microgrid typically has limited generation capability, a microgrid operator (MGO) has to take the risk of ...

Planned Islanding Algorithm Design Based on Multiple Sub-Microgrids With Dynamic Boundary
IEEE Open Access Journal of Power and Energy, 2021 Planned islanding is one of the fundamental functions of microgrid (MG) controllers. However, existing planned islanding functions cannot be directly utilized in MGs that have the capability to have both dynamic boundary and multiple sub-MGs. To optimize

A Learning Scheme for Microgrid Islanding and Reconnection
CoRR, 2016 This paper introduces a potential learning scheme that can dynamically predict the stability of the reconnection of sub-networks to a main grid. As the future electrical power systems tend towards smarter and greener technology, the deployment of self sufficient networks, or microgrids, becomes more likely.
