Fast Frequency Support From Grid-Forming Converters Under dc- and ac-Side Current Limits
IEEE Transactions on Power Systems, 2023A decentralized nonlinear feedback controller is proposed for droop-based grid-forming converters (GFCs) with both dc-side current limitation and ac-side current limit to provide fast frequency support from renewable resources after a large generation ...

Forecasting Frequency-Corrected Electricity Demand to Support Frequency Control
IEEE Transactions on Power Systems, 2016Electricity demand forecasts are needed for decisions regarding generation dispatch for lead times as short as just a few minutes. Imbalance between generation and demand causes deviation of the system frequency from its target, which in Great Britain is 50 Hz. This, in turn, causes a change in demand, due largely to motor loads. For Great Britain, the

Frequency Stabilization of a VCDRO by Microcontroller Supported Frequency Lock Loop
2007 8th International Conference on Telecommunications in Modern Satellite, Cable and Broadcasting Services, 2007The paper presents frequency stabilization of a VCDRO operating at 11 GHz by using a frequency lock loop supported by microcontroller. The signal from a PLL synthesizer is used as a reference signal in the FLL in order to obtain a signal with characteristics like one originating from a free- running VCDRO having, in the same time, stability close to a ...

Distributed generation control for frequency support
IET Conference Publications, 2009This paper investigates a new technique that could be applied to control distributed generation units in an islanded distribution network to support frequency. The frequency control technique relies on slow communication in order to establish the units that are in operation.
