Adaptive Virtual Inertia Control Method Based on Droop Control

2021 IEEE 30th International Symposium on Industrial Electronics (ISIE), 2021
With the increasing proportion of renewable energy in microgrids, traditional droop control without inertia can hardly meet the needs of inverter control. Load changes can cause sudden changes in the frequency of the microgrid system, which can easily trigger the protection device of the system. The stable operation of the microgrid is affected. At the

Synthesis of Robust Virtual Inertia Control

2020
Regarding the previously elaborated inertia control techniques, they are not explicitly designed to deal with the effect of high uncertainty and disturbance. Thus, it is difficult to achieve a suitable trade-off between robust and nominal performances. In adaptive control techniques, the uncertainty formulation may not be appropriately included in the ...

An Overview of Virtual Inertia and Its Control

2020
Today, 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

Research on virtual inertia control of the DC microgrid

IET Conference Proceedings, 2021
The 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 ...

Fuzzy virtual inertia control for virtual synchronous generator

2016 35th Chinese Control Conference (CCC), 2016
The 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, 2005
This 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 ...
