Parallel operation of virtual synchronous generators and synchronous generators in a microgrid
The Journal of Engineering, 2019 Aiming for integration of a large-scale of distributed generators (DGs) such as photovoltaic into the microgrids, the virtual synchronous generator (VSG) control concept has been developed.

IEEE Transactions on Energy Conversion, 2020 In recent years, the increasing penetration of distributed generation in microgrids challenges the control and coordination of energy resources. Especially in microgrids with virtual synchronous generator (VSG)-controlled converters and conventional synchronous generators (SG), the inherent inertia difference (i.e., the VSG and SG) results in a poor ...

Identification of Internal Electromagnetic Defects of Implicit-Pole Synchronous Generators Based on the Information of its External Magnetic Field [PDF]
Problems of the Regional Energetics, 2022 The objectives of the work are to develop a non-contact method of detecting internal electro-magnetic defects in synchronous generators based on the analysis of asymmetry of the external magnetic field distribution resulting from damage, establishing the

Quantum Synchronization and Entanglement Generation [PDF]
Physical Review Letters, 2018 We study synchronization in a two-node network built out of the smallest possible self-sustained oscillator: a spin 1. We first demonstrate that phase locking between the quantum oscillators can be achieved, even for limit cycles that cannot be synchronized to an external semi-classical signal. Building upon the analytical description of the system, we

The reservoir’s perspective on generalized synchronization [PDF]
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2019 We employ reservoir computing for a reconstruction task in coupled chaotic systems, across a range of dynamical relationships including generalized synchronization. For a drive-response setup, a temporal representation of the synchronized state is discussed as an alternative to the known instantaneous form.

Energies, 2021 Generally, the fault current supplied by inverter-based renewable energy sources (IBRES) and electrical storage systems (ESS) is about 1.2 to 2 times their rated current and much lower than synchronous generators because the former acts as a current ...
