How can we assess the performance of a microgrid?

This framework can effectively assess the multi-dimensional performance of the microgrid considering three key performance indicators, including economics, renewable energy penetration and reliability. The proposed framework is tested and verified on an islanded microgrid located on an island in the subtropical region.

What are the key indicators of a microgrid?

Reliability Reliability (Re) is another key indicator. It is used to assess the power balance of the microgrid. It refers to “the ability to meet the electricity needs of end-use customers, even when unexpected equipment failures or other conditions reduce the amount of available power supply” [ 35 ].

How can a microgrid assessment framework improve performance?

The proposed assessment framework can quantify and analyze the correlation among three key indicators of the microgrid system performance comprehensively at the planning stage; The computation cost of the assessment framework can be significantly reduced while offering acceptable accuracy;

What are microgrids & how do they work?

Microgrids 12, 13 are small, localized energy systems that can generate, store and distribute energy independently or in conjunction with the main energy grid. In this context, community power storage systems are gaining relevance 14 and can serve as nuclei for microgrids in urban areas, offering potential interconnection possibilities 13, 15, 16.

Why do microgrid systems need a preliminary assessment?

However, for those large-scale or/and complex microgrid systems, the assessments of the system performance at the planning stage are conducted first due to the high computation cost. The preliminary assessment results provide guidelines for further system optimal design.

How is microgrid multi-dimensional performance assessment quantified?

Microgrid multi-dimensional performance assessment quantification. At this step, the parameters of the empirical cost model are identified according to the obtained key indicators. Then, the quantitative assessment results can be obtained using the empirical model. Fig. 1.
