A negative sequence current injection (NSCI)-based active protection scheme for islanded microgrids
The growing penetration of converter interfaced generation creates unprecedented challenges to protection strategies at all voltage levels. This paper proposes a novel Negative Sequence Current Injection (NSCI)-based active protection scheme for islanded

A Negative-sequence Current Injection Method to Mitigate Voltage Imbalances in Microgrids [PDF]
This paper proposes a control strategy to reduce the voltage imbalances by injection of a proper negative-sequence current into the microgrid. This task can be done by each inverter connected to the microgrid in a shared way.

Influence of Negative Sequence Injection Strategies on Faulted Phase Selector Performance
Renewable power is expected to increase drastically in the coming years due to the energy transition. A large part of the newly installed generators will be connected to the power system through inverters and electronic converters, whose behaviour ...

A low voltage ride-through control method of IIDG considering multiple control targets [PDF]
There are some disadvantages in existing inverter-interfaced distributed generators (IIDG) low voltage ride-through control methods,such as unsatisfactory voltage support effects,single control objectives,and the risk of over-limiting the output current.

Development of a Novel Control Scheme for Grid-Following Converter under Asymmetrical Faults
With the increasing penetration of converter-based power sources into the power system, the performance of the converter has become a key factor for enhancing grid reliability, especially during asymmetrical faults.

Power Capability Boundaries for an Inverter Providing Multiple Grid Support Services
It is getting more common every day to install inverters that offer several grid support services in parallel. As these services are provided, a simultaneous need arises to know the combined limit of the inverter for those services. In the present paper,
