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
