A PARAMETRIC SENSITIVITY FORMULATION FOR POWER SYSTEM ANALYSIS

The paper presents the development of a Parametric Sensitivity approach based on the Modified Nodal Formulation (MNF) for Power System Analysis. This technique is called the Modified Nodal Formulation Sensitivity Analysis (MNFSA). The algorithm and development of the mathematical formulations for the MNFSA that was built into a computer program is illustrated. The developed program offers a new tool to help in analyzing the quality of power system design by studying the effect of adding, removing and changing the characteristics of different power system equipment. The paper lists the MNFSA capabilities in identifying system problems, the parameters that are causing these problems, the interaction between the capacitive and reactive system parameters, and in devising solutions and mitigation methods. The MNFSA can be applied to assist in identifying power quality issues related to harmonic over voltages and resonance in power systems. This application includes identifying the route cause of problems such as resonance phenomena and harmonic amplification and assets in finding solutions to these problems.
