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.

Two-stage frequency regulation for wind turbines with adaptive coefficients and optimized power trajectory [PDF]
International Journal of Electrical Power & Energy SystemsWind turbines support grid frequency by rotor decelerating and then accelerating, but the instant power imbalance caused by rotor speed recovery may lead to a secondary frequency drop.

Model‐based receding horizon control of wind farms for secondary frequency regulation [PDF]
Wind Energy, 2017 AbstractIn this study, we propose the use of model‐based receding horizon control to enable a wind farm to provide secondary frequency regulation for a power grid. The controller is built by first proposing a time‐varying one‐dimensional wake model, which is validated against large eddy simulations of a wind farm at startup.

A hierarchical control scheme for optimal secondary frequency regulation with on-off loads in power networks [PDF]
2020 59th IEEE Conference on Decision and Control (CDC), 2020 Load side participation can provide support to the power network by appropriately adapting the demand when required. In addition, it may allow for 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 ...

Stability and optimality of distributed schemes for secondary frequency regulation in power networks [PDF]
2016 IEEE 55th Conference on Decision and Control (CDC), 2016 We present a method for designing distributed generation and demand control schemes for secondary frequency regulation in power networks such that asymptotic stability and an economically optimal power allocation can be guaranteed. A dissipativity condition is imposed on net power supply variables to provide stability guarantees.

Energy Procedia, 2019 Abstract The number of electric vehicles (EVs) has been rapidly increasing, leading to the importance to predict the most beneficial way to integrate them with electrical grids. Continuous charging and discharging of EVs make their batteries degrade, resulting in a need for them to be replaced.

A dual-driven predictive control for photovoltaic-diesel microgrid secondary frequency regulation [PDF]
, 2023 Photovoltaic (PV) panel generator is inherently fluctuant due to its dependence on weather. If this generator connects to power grids or microgrids (MGs), the frequency of renewable-energy-based power grids or MGs will not be stable. Hence, in this paper,
