6 FAQs about [Microgrid grounding protection]

How to ground a microgrid?

Grounding of microgrids is one of the most challenging topics for microgrid protection. In grid-connected mode, the system grounding is generally provided by the substation transformer.

Why do we need a grounding system for a dc microgrid?

As this current has high value, it has to be interrupted to prevent the VSC from being damaged. The type of grounding system could also influence on safety, the ability to identify the fault, and survivability of DC microgrid under faulty conditions.

What are the barriers to implementing a dc microgrid?

Although many efforts have been made to develop standards to facilitate implementation of DC microgrid, there is still a lack of practical standardisation on grounding systems for different voltage levels, cyber-security, and protection system. Proper protection of AC and DC microgrids is one of the last barriers for implementing microgrids.

Why is dc microgrid protection important?

Protection has to be a part of the DC microgrid system design. While this fact appears to be a detriment, if in fact DC microgrid protection is an integral part of the DC microgrid system design, proper implementations may be discovered that make the DC microgrid even more applicable for wide range of applications.

How to protect DC microgrids during fault scenarios?

According to the distinct characteristics of DC microgrids during fault scenarios, a proper protection system must be a key consideration. Systematic considerations, such as grid topology, grounding and interactions between inter-connected converters during fault events must be included as an integral part of the system design process.

What happens if a microgrid is grounded in grid-connected mode?

In grid-connected mode, the system grounding is generally provided by the substation transformer. If the microgrid or DER in the microgrid are grounded during grid-connected operation, it can result in bi-directional ground current flows, desensitization of ground current protection settings, and sympathetic tripping.
