Secondary control with reduced communication requirements for accurate reactive power sharing in AC microgrids

open access: yesIET Smart Grid, 2023
A secondary control method is proposed for accurate reactive power sharing as well as frequency and voltage restoration in islanded AC microgrids (MGs).

Synthesis of Hierarchical Systems

open access: yesScience of Computer Programming, 2012
In automated synthesis, given a specification, we automatically create a system that is guaranteed to satisfy the specification. In the classical temporal synthesis algorithms, one usually creates a ''flat'' system ''from scratch''. However, real-life software and hardware systems are usually created using preexisting libraries of reusable components ...

Power-Flow-Based Secondary Control for Autonomous Droop-Controlled AC Nanogrids With Peer-to-Peer Energy Trading

open access: yesIEEE Access, 2021
Regarding the control of micro- and nanogrids, LC- or LCL-filtered power inverters (acting as interfaces with distributed energy resources such as photovoltaic or wind) commonly perform as grid-forming or grid-supporting units to maintain both the ...

Hierarchical interface-based supervisory control using the conflict preorder [PDF]

open access: yes, 2012
Hierarchical Interface-Based Supervisory Control decomposes a large discrete event system into subsystems linked to each other by interfaces, facilitating the design of complex systems and the re-use of components.

Coordinated active and reactive power control for overvoltage mitigation in physical LV microgrids

open access: yesThe Journal of Engineering, 2019
The share of photovoltaic (PV) systems in the distribution networks is rapidly growing, leading to the common issue of overvoltage at the end of distribution feeders during the periods when peak generation is surplus to consumption.

Routing performance in a hierarchical DHT-based overlay network [PDF]

open access: yes, 2008
The scalability properties of DHT based overlay networks is considered satisfactory. However, in large scale systems this might still cause a problem since they have a logarithmic complexity depending.

A Repairable System Subjected to Hierarchical Competing Risks: Modeling and Applications

open access: yesIEEE Access, 2019
In this paper, we propose modeling for a single repairable system with a hierarchical structure under the assumption that the failures follow a nonhomogeneous Poisson process (which corresponds to minimal repair action) with a power-law intensity ...
