"A Hierarchical Service Restoration Framework for Unbalanced Active Dis" by Ghulam Mohy-ud-din, Kashem M. Muttaqi et al.

Modern active distribution networks (ADNs) have become more resilient to service interruptions due to the flexibility offered by integrated distributed energy resources (DERs). Compared to network-owned DERs, directly controlled by the distribution system operator (DSO), a vast majority of DERs controlled by independent virtual power plants (VPPs) are much more difficult to coordinate. The coordination with the VPPs and the management of uncertainty are the two major obstacles in the utilization of these DERs in the ADN restoration (ADNR). This paper proposes a hierarchical framework for the sequential ADNR to overcome these two obstacles. The proposed framework adaptively integrates the sequential ADNR planning and the VPP scheduling models based on a comprehensive DSO and VPP coordination scheme to quantify and include the flexibility of VPPs in the ADNR. Furthermore, to address the uncertainty of renewable DERs and loads, a chance-constraint (CC) approach is used in these models. As ....

"An Adaptable Correlated Control for Maintaining Voltage Quality in Low" by Arian Zahedmanesh, Kashem Muttaqi et al.

Rooftop photovoltaic (PV) systems and plug-in electric vehicles (PEVs) will be increasingly utilized by residential customers due to their economic and environmental benefits. However, the intermittent power produced by PVs and the additional loads required for the PEV charging can cause power quality disturbances in the low voltage distribution networks (LVDN). An adaptable correlated control (ACC) is proposed for the decoupled optimization of the active and reactive power, where energy cost can be minimized through the local demand side management (DSM) of residential loads. Further, the optimal allocation of the sparse capacity of inverters for reactive power compensation to maintain the voltage variations and the mitigation of voltage unbalances within the allowable limits is proposed. The proposed ACC provides a supervisory control to observe and modify the voltage quality of the LVDN without the need for real-time collaboration between controllers. The impacts of the integration ....
