Aggregated Energy Storage for Power System Frequency Control: A Finite-Time Consensus Approach
IEEE Transactions on Smart Grid, 2019 In future power systems, widespread small-scale energy storage systems (ESSs) can be aggregated to provide ancillary services. In this context, a new load frequency control scheme which incorporates the energy storage aggregator (ESA) and its associated ...

Equivalent Modeling of Dfig-Based Wind Farms for Sub-Synchronous Resonance Analysis
Energies, 2020 The order of the detailed model of doubly-fed induction generator (DFIG) wind farms are too high and the simulation is difficult. Most of the existing research has used a single-machine equivalent model and clustering aggregation model for equivalence ...

Design of robust current tracking control for active power filters [PDF]
, 2001 The paper describes a design methodology for robust current-tracking control of active power filters using quantitative feedback theory (QFT). The design aim is to address system issues of power quality and power factor correction in a double-sided ...

USER-ORIENTED POWER SYSTEM CONTROL
IFAC Proceedings Volumes, 1987 Abstract The aim of power system control is to translate the behaviour of a power system under all operating conditions with respect to time and information in a form to which the operator can respond. Starting by defining the duties and needs of the operator in the different operational states, an attempt is made to list the “user oriented ...

Electronic system for high power load control [PDF]
, 1980 Parallel current paths are divided into two groups, with control devices in the current paths of one group each having a current limiting resistor, and the control devices in the other group each having no limiting resistor, so that when the control ...

Developmental Disorders in Children Recently Diagnosed With Cancer
Pediatric Blood &Cancer, EarlyView.ABSTRACT Neurocognitive deficits in adult survivors of childhood cancer are well established, but less is known about developmental disorders (DD) arising shortly after cancer diagnosis. Using 2016–2019 linked Ohio cancer registry and Medicaid data, we compared DD among 324 children with cancer and 606,913 cancer‐free controls.
