6 FAQs about [Microgrid resistance]
Can microgrids improve distribution system resilience?
In this regard, microgrids, as the smart grid’s building blocks, offer promising approaches toward achieving higher levels of distribution system resilience by accommodating and integrating various distributed energy resources.
What is microgrid resilience?
It is important to note that the topic of microgrid resilience, including its mitigation measures, has techno-economic, social-economic, and socio-technical aspects interwoven into it; where there are wide variations in the human judgment of the risk and existing vulnerabilities in the system as well as economic considerations.
What is a microgrid?
The term “microgrid” refers to the concept of a small number of DERs connected to a single power subsystem. DERs include both renewable and /or conventional resources . The electric grid is no longer a one-way system from the 20th-century . A constellation of distributed energy technologies is paving the way for MGs , , .
How does integrated microgrid planning bolster urban resilience?
Our approach integrates social and technical indicators to bolster urban microgrid planning. Through a case study in a US county, we illustrate how integrated microgrid planning effectively intertwines urban resilience, well-being and equity while promoting sustainable development.
Are microgrids a risk mitigation strategy to increase energy resilience?
Microgrids are one possible risk mitigation strategy to increase energy resilience and the decision to conduct a microgrid assessment should be part of a broader effort to increase energy resilience and should also include an analysis of other options.
Can microgrids reduce urban resilience?
As an interim result, the fact that individual microgrids can fail makes it clear that the risk for lack of well-being and urban resilience in a city can be reduced with the use of multiple microgrids instead of one. These points are ultimately confirmed by our study (Fig. 5 ).
