Power Grid Infrastructures | Encyclopedia MDPI

In existing protection methods, a microgrid can cause many challenges in terms of the protection of blinding zones, false tripping of protective relays, decreasing fault levels, islanding, and auto-reclosers .

Microgrid

A microgrid is a local electrical grid with defined electrical boundaries, acting as a single and controllable entity. [1] It is able to operate in grid-connected and in island mode. [2] [3] A ''stand-alone microgrid'' or ''isolated microgrid'' only

6 FAQs about [Microgrid Protection Encyclopedia]

Can a microgrid protect a power system?

Protection systems need to be reviewed to consider the integration of distributed generation technologies. The presence of a microgrid causes many challenges in the protection of the power system. This study addressed these challenges and their solutions.

Are microgrids a threat to protection systems?

While microgrids have many benefits for power systems, they cause many challenges, especially in protection systems. This paper presents a comprehensive review of protection systems with the penetration of microgrids in the distribution network.

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.

How to protect a microgrid with a communication network?

References [42, 44] proposed the protection of a microgrid with a communication network using digital relays. These methods use differential protection for low fault currents, such as in an HIF and inverter-based-microgrid. In Reference , a communication-assisted OC protection scheme was proposed for PV in DC microgrids.

Which protection scheme is used in a dc microgrid?

The protection scheme in grid-connected and islanded operation mode of a DC microgrid uses OC relays. Otherwise, a protection scheme has been suggested based on differential protection. Reference has presented a protection scheme in the loop distribution system in the presence of DGs.

What is the framework of microgrid protection system?

The framework of microgrid protection system should be meticulous, reliable and must have high speed and low-cost operation. The process of microgrid protection must have following steps as shown in Fig. 4, which need to be followed starting from the occurrence of fault to the restoration of the normal operation of the system. Fig. 4.
