6 FAQs about [Microgrid grid-connected reliability assessment]

How to evaluate the reliability of a microgrid design?

To evaluate the reliability of the proposed design, reliability concepts for power system application can serve as a basis to which the microgrid-specific aspects can be added. To estimate the significance and the severity of the events leading to the system interruptions, a quantitative reliability analysis is necessary.

How can microgrids improve power electronic reliability?

New design methods incorporating power electronic reliability need to be developed. Microgrids are highlighted as the technology which can help in providing sustainable and efficient electrical energy solutions. They employ distributed energy resources to efficiently supply local load and increase the reliability of the local network.

Which reliability indices provide supplementary information about microgrid performance?

In this study, we propose three new reliability indices to provide supplementary information regarding performance of MG: the Microgrid Resiliency Index (MRI), the Microgrid Renewable Energy Availability Index (MREAI), and the Microgrid Renewable Energy Energy Index (MREEI). MRI measures a MGs ability to recover from outages and disturbances.

How are reliability indices determined in a cost-effective microgrid system?

When the reliability analysis is done within the cost assessment, the reliability indices are not determined separately. In such case, the reliability is defined through the relevant reliability cost index. Those are included in , where the main target is the optimal DER size for design of cost-effective microgrid system.

Why is microgrid design and planning important?

Microgrid design and planning is important in assuring high reliability. Overview of practices helps indicating reliability critical parts of design. Microgrids will be dominated by power electronics interfaced distributed resources. Excluding power electronics reliability can impact finding optimum design solution.

How will microgrids be dominated by power electronics interfaced distributed resources?

Microgrids will be dominated by power electronics interfaced distributed resources. Excluding power electronics reliability can impact finding optimum design solution. New design methods incorporating power electronic reliability need to be developed.
