Assessment of black-start schemes for power grid based on relational matrix analysis;

Meanwhile, as a system evaluation method based on matrix modules, relational matrix analysis has the advantage of combining objectiveness with subjective evaluation.

Distribution network flow calculation basedon incidence matrix squaring;

A method to establish OOPN incidence matrix for net performance analysis;

Consumable gas of compressor stations was not taken into consideration when branched gas pipeline networks flow equations were described with the incidence matrix method in the past,which would result in unavoidable deviation.

Then, the reengineering algo- rithm of incident matrix was employed to describe all the activities.

On this basis,it discusses,by using determinant,the calculation method of the number of tree graph vertices of the known connecting graph according to the nature of the basic incident matrix.

Furthermore, an incident matrix_based reengineering algorithm is proposed and used to describe the activity patterns determined.
