Microgrid Assessment Index Analysis

Is a power quality assessment method suitable for microgrid systems?

The proposed method is suitable for both single-node and multi-node power quality assessment scenarios in microgrid systems. Compared with the traditional power quality evaluation method, the method proposed in this paper reflects the actual power quality problems of the microgrid more objectively and accurately.

How to evaluate power quality of microgrid with dynamic weighting?

Comprehensive power quality evaluation method of microgrid with dynamic weighting based on CRITIC is proposed in this paper. Based on the single-node evaluation method of the CRITIC method, the load capacity is also considered to attain a comprehensive weighting factor, therefore a multi-node evaluation method can be obtained.

Can a multi-node evaluation method be used in microgrid systems?

Based on the single-node evaluation method of the CRITIC method, the load capacity is also considered to attain a comprehensive weighting factor, therefore a multi-node evaluation method can be obtained. The proposed method is suitable for both single-node and multi-node power quality assessment scenarios in microgrid systems.

Why is microgrid important?

In addition, it also can reflect the dynamic changes of microgrid. Finally, an example is used to verify the feasibility of the proposed method. Microgrid is one of the reasonable ways to connect distributed power generation system to the grid.

How does the critic method affect the power quality of a microgrid?

In this paper, the CRITIC method is used to evaluate the power quality of a single node, and the node dynamic coefficient is added. In other words, when the large-capacity load of the microgrid changes, the impact of loads on the microgrid is also changed.

What are the characteristics of a microgrid?

Its characteristics include low environmental pollution, flexible operation mode, and strong power supply reliability, therefore it has been extensively studied. 1 – 3 However, compared with traditional power grids, microgrids have the characteristics of small capacity and low inertia.
