"Event-triggered SMC-based FRT Approach for DFIG-based Wind Turbines Eq" by Md Nafiz Musarrat, Afef Fekih et al.

This paper proposes an event-triggered sliding mode control (SMC)-based fault ride through (FRT) strategy for doubly-fed-induction-generator (DFIG)-based wind turbines. An event-triggered SMC (ETSMC) approach is designed for a dynamic voltage restorer (DVR) with a high frequency isolated dc-dc converter. The aim is to regulate the stator terminal voltage by injecting appropriate voltage to regulate it near the reference point. Since the control signal in the event-triggered SMC is only updated when certain conditions are violated, the proposed approach results in reduced computational burden and channel bandwidth. Additionally, it reduces the chattering phenomena typically associated with SMC and reduces harmonic distortion. The ETSMC is augmented by a disturbance observer to further improve its robustness against mismatched uncertainties. The DVR topology considered in this paper utilizes high frequency isolation transformer, which dramatically reduces the costs associated with the re ....

"Graph Theory Based Voltage Sag Mitigation Cluster Formation Utilizing " by Subir Majumder, Shrikrishna A. Khaparde et al.

Voltage sag mitigation utilizing dynamic voltage restorers (DVRs) can be classified as a common-pool resource (CPR) good. However, the ability of DVRs in improving voltage sag performance of only downstream customers provides the ability to exclude the non-contributors selectively. Therefore, unlike traditional CPR goods, the DVR allocation problem can give rise to partial excludability. Here, the non-collocated customers have been divided into feasible clusters through suitable positioning of DVRs using the proposed graph-partitioning principle. In the absence of trustworthiness, especially with the participation of electricity supply companies, the participants may ask an external agent and share their willingness-to-pay information to design the optimal set of clusters. Alternatively, the customers, including electricity supply companies, can also share internal information as an open system. Strategies for sharing internal information to avoid free-riding are also discussed. The ut ....
