Optimal Allocation of Synchronous Condensers in Wind Dominated Power Grids
IEEE Access, 2020 System strength (also known as short-circuit performance) indicates the capability of a power system to recover a fault. Renewable energy integration in power grids causes replacement and retirement of synchronous generators from generation fleet, which ...

International Journal of Adaptive Control and Signal Processing, EarlyView.This paper proposes two projector‐based Hopfield neural network (HNN) estimators for online, constrained parameter estimation under time‐varying data, additive disturbances, and slowly drifting physical parameters. The first is a constraint‐aware HNN that enforces linear equalities and inequalities (via slack neurons) and continuously tracks the ...

Robustness of the European power grids under intentional attack [PDF]
, 2007 The power grid defines one of the most important technological networks of our times and sustains our complex society. It has evolved for more than a century into an extremely huge and seemingly robust and well understood system. But it becomes extremely

Synchronous Power Control of Grid-Connected Power Converters under Asymmetrical Grid Fault [PDF]
Energies, 2017 Control of grid-connected power converters is continuously developing to meet the grid codes, according to which the generation units should keep connected to the grid and further provide ancillary services, such as voltage and frequency support, negative sequence current injection, inertia emulation, etc. A virtual admittance controller is proposed in

Electricity Theft Detection in Power Grids with Deep Learning and Random Forests
Journal of Electrical and Computer Engineering, 2019 As one of the major factors of the nontechnical losses (NTLs) in distribution networks, the electricity theft causes significant harm to power grids, which influences power supply quality and reduces operating profits.

Generic System Frequency Response Model for Power Grids With Different Generations
IEEE Access, 2020 With the increasing integration of renewable generation, many power grids have gradually formed AC–DC hybrid systems. Abnormal operations, such as DC blocking faults and generation trips, have led to several incidents of large frequency deviations ...
