Study on Secondary Non-Differential Frequency Modulation Control Strategy of VSG in Islanding Mode

IEEE Access, 2023
The microgrid under VSG control is conducive to the security and stability of the microgrid system. However, it still belongs to the primary regulation of frequency, and the microgrid in islanding mode has the problem that the frequency cannot be ...

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.

Power systems with high renewable energy sources: A review of inertia and frequency control strategies over time [PDF]

, 2020
Traditionally, inertia in power systems has been determined by considering all the rotating masses directly connected to the grid. During the last decade, the integration of renewable energy sources, mainly photovoltaic installations and wind power ...

Distributed secondary control of microgrids with unknown disturbances and non-linear dynamics

Frontiers in Energy Research, 2023
In this paper, the voltage and frequency regulation of microgrid with unknown disturbances and non-linear dynamics was studied. The disturbance observer was designed and the sliding mode control (SMC) method was used to realize the secondary regulation ...

Hierarchical frequency control strategy of doubly-fed induction diesel generator under emergency condition

Energy Reports, 2022
Natural disasters lead to the uncertain topological structure of the urban distribution network. It is difficult for the communication system to recover quickly, which brings great difficulties to restoring the power supply.
