Hierarchical Control of Thermostatically Controller Loads for Primary Frequency Control [PDF]
IEEE Transactions on Smart Grid, 2018 This paper proposes a hierarchical control of thermostatically controlled loads (TCLs) to provide primary frequency control support. The control architecture is composed of three levels. At the high level, an aggregator coordinates multiple distribution substations and dispatches the primary reserve references.

Distributed Primary Frequency Control through Multi-Terminal HVDC Transmission Systems [PDF]
2015 American Control Conference (ACC), 2015 This paper presents a decentralized controller for sharing primary AC frequency control reserves through a multi-terminal HVDC grid. By using Lyapunov arguments, the proposed controller is shown to stabilize the equilibrium of the closed-loop system ...

Frequency‐trajectory‐oriented control strategy for primary frequency regulation of wind farms
IET Generation, Transmission & Distribution, 2023 With the rapid increase of wind power penetration, the frequency indicators of power system, encompassing frequency deviation and rate of change of frequency (RoCoF), are prone to exceed the pertinent relay thresholds, thus leading to serious power ...

A Novel Decentralized Responsibilizing Primary Frequency Control [PDF]
IEEE Transactions on Power Systems, 2018 There is an emerging need to prioritize remedial frequency control measures closer to the source of an imbalance event. This approach, referred to herein as responsibilization, is challenging to achieve within the conventional operating times of Primary Frequency Control (PFC) and therefore novel methods are sought.
