A distributed control for accurate active-power sharing in islanded microgrids subject to clock drifts
(2021-01-28)
Article
Open AccessInverters-based islanded microgrids are operated by local digital signal processors, driven by their own local clocks. These local clocks have drifts affecting the clock signals which are used to control the inverters in ... -
Active power sharing and frequency regulation in droop-free control for islanded microgrids under electrical and communication failures
(Institute of Electrical and Electronics Engineers (IEEE), 2020-08-01)
Article
Open AccessThe droop-free control for ac microgrids achieves active power sharing and frequency regulation by replacing the centralized secondary control and the primary-level droop mechanism by a cooperative distributed control ... -
An alternative discrete-time model for networked control systems with time delay less than the sampling period
(2013)
Conference lecture
Restricted access - publisher's policyThe majority of existing Networked Control Systems (NCS) models are discrete-time formulations based on the exact discretization of the continuous-time linear plant over a sample interval. In the state-space formalism, ... -

Analysis of the effect of clock drifts on frequency regulation and power sharing in inverter-based islanded microgrids
(2018-02-12)
Article
Open AccessLocal hardware clocks in physically distributed computation devices hardly ever agree because clocks drift apart and the drift can be different for each device. This paper analyses the effect that local clock drifts have ... -
