Research on virtual inertia control of the DC microgrid
IET Conference Proceedings, 2021The inertia support of DC microgrid system is less, the instability of output power of distributed generation and the sudden change of load cause the sharp fluctuation of DC voltage, which endangers the safe and stable operation of DC microgrid. In order to solve the problem of small inertia of DC microgrid, a virtual inertial control strategy with ...

An Overview of Virtual Inertia and Its Control
2020Today, due to the widespread penetration of renewable energy sources (RESs) and distributed generators (DGs), a new power system stability issue has emerged. This issue is the reduction and variation of inertia in the power system and is triggered by the utilization of power electronics interfaces to connect the RESs and DGs into the system, leading to

Fuzzy virtual inertia control for virtual synchronous generator
2016 35th Chinese Control Conference (CCC), 2016The virtual synchronous generator (VSG) control scheme regulates the inverter as a synchronous generator (SG). As the SG plays an important role in the conventional grid by supporting system stability, the VSG can act the same role in a micro-grid.

Virtual Torque and Inertia Loading of Controlled Electric Drive
IEEE Transactions on Education, 2005This work presents a simple method to obtain effects similar to those obtained by real mechanical loading and real inertia variation but without any mechanical parts supplementary to the electric motor of the studied electric drive. The electric motor itself produces the load torque and the inertia variation using digital signal processing software ...

An Improved Virtual Inertia Control for Three-Phase Voltage Source Converters Connected to a Weak Grid [PDF]
IEEE Transactions on Power Electronics, 2019 The continuous increasing share of power-converter-based renewable energies weakens the power system inertia. The lack of inertia becomes a main challenge to small-scale modern power systems in terms of control and stability. To alleviate adverse effects

DFIG Virtual Inertia Frequency Control Strategy
Advanced Materials Research, 2013During the DFIG maximum power tracking control process, the rotor side converter is only based on the wind turbine speed to regulate the active power output; it almost no provides effective inertia. DFIG could add auxiliary virtual inertia control system, when the system frequency is reduced, releasing the rotor "hidden" kinetic energy to support the ...

Fuzzy Logic Control for Virtual Inertia Synthesis
2020Currently, renewable energy sources (RESs) and distributed generators (DGs) are highly integrated into power systems regarding energy crisis, environmental concerns, and economic growth. The RESs/DGs penetration brings more complexity to the power system, since its systems are decentralized, and power outputs are intermittent or unpredictable against ...
