A new method for analyzing unsymmetrical faults under data uncertainties

An interval power flow for unbalanced distribution systems based on the Three-Phase Current Injection Method

“…It is important to notice that voltage control and frequency droop equations can be considered directly in the formation of the Jacobian matrix of the current injection method, as described in equations (A.15)-(A. 19) in Appendix A, according to the original Ref. [32] in which this important contribution is presented.…”

“…Ref. [18] proposes the incorporation of AA in the formulation of single-phase power flow using the CIM and an interval power flow is proposed in [19] based on the CIM for evaluating symmetrical and asymmetrical faults. In these methodologies, the load flow solution is obtained using rectangular coordinates as state variables to be determined iteratively by Newton-Raphson and only single-phase systems with meshed topology are used in the case studies.…”
