6 FAQs about [Microgrid protection scheme]
Do microgrid protection schemes meet operational requirements?
The microgrid protection scheme must meet the essential conditions for grid-connected and islanded operational modes. This paper presents a comprehensive review and comparative analysis of protection schemes and their implementation challenges for different microgrid architectures with various operational requirements.
What is a microgrid protection scheme?
The protection schemes try to provide an appropriate protection strategy which can protect microgrids in both grid-connected and islanded modes. In general, it can be identified solutions based on simple protection functions supported using Intelligent Electronic Devices (IED) with communications.
How to design a microgrid protection system?
Some of the major points to address in the design of the protection schemes for microgrids are: (1) DER with high penetration level and islanded operation mode; (2) the protection system must be adequate for configuration changes; and (3) the architecture of the protection system.
Do microgrid protection systems work for different operating conditions?
A major challenge associated with the implementation of microgrids is to design a suitable protection system scheme for different operating conditions. To overcome this challenge, different approaches have been proposed in the literature. The protection systems applied at microgrids must work both in utility grid faults and microgrid faults.
What are the limitations of microgrid protection schemes?
From the review, it is clear that most of the existing protection schemes (advance and traditional) have more or less limitations, which need to improve for better performance of microgrids. The traditional protection schemes make the microgrid system bulky. The time for trip signal is also high and cannot detect low voltage faults.
Which protection scheme is suitable for large-scale microgrids?
As the opposite, for large-scale microgrids, a distributed protection scheme with a limited connectivity model could be suitable. The adaptive protection scheme is considered a possible solution for microgrid protection system. This strategy has the advantage of using mature technologies and conventional protection functions.
