| Popis: | The comparative analysis of load flow calculation methods are outlined in this study. Which is based on voltage stability constraints methodology to define an appropriate method for voltage stability studies at the critical point. Study of voltage stability and reliability analysis require a comprehensive investigation and stimulation efforts as an indispensable part of a power system operation and control. The critical point assessment is inclination point for researchers and power system operators. On the other hand, the load flow calculation at the critical point is the basis of voltage stability and reliability studies. So, the discernment of an appropriate calculation technique is essential. In this paper, the Jacobian matrix-based and variable-based, load flow techniques' comparative analysis are addressed. Which, a sharper focus is given on calculation deficiencies such over-determined system, minimal norm solutions for the under-determined systems, and singularity of the Jacobian matrix. |
