Advances in Computer and Materials Scienc ResearchAs the share of wind power in the power generation structure increases, the demand for effective frequency regulation using wind turbines also grows. Wind turbines typically participate in frequency regulation by reducing rotor speed. However, extended operation at low speeds can lead to efficiency losses, which necessitate measures to disengage from ...

Optimal Secondary Frequency Regulation With ON-OFF Loads in Power Networks
IEEE Transactions on Control Systems Technology, 2022 Load side participation can provide support to the power network by appropriately adapting the demand when required. In addition, it enables an economically improved power allocation. In this study, we consider the problem of providing an optimal power allocation among generation and on-off loads within the secondary frequency control timeframe.

Privacy and optimality of distributed schemes for secondary frequency regulation in power networks
2022 IEEE 61st Conference on Decision and Control (CDC), 2022 The increasing participation of local generation and controllable demand units within the power network motivates the use of distributed schemes for their control. Simultaneously, it raises two issues; achieving an optimal power allocation among these units, and securing the privacy of the generation/demand profiles. This study considers the problem of

Secondary frequency regulation in power networks with on-off load side participation [PDF]
2017 IEEE 56th Annual Conference on Decision and Control (CDC), 2017 We study the problem of secondary frequency regulation where ancillary services are provided via load-side participation. In particular, we consider on-off loads that switch when prescribed frequency thresholds are exceeded in order to assist existing secondary frequency control mechanisms.
