EXPLORATORY ASSESSMENT OF THE DYNAMIC BEHAVIOR OF MULTIMACHINE SYSTEMSTABILIZED BY A SMES UNIT

A new linear model of superconducting magnetic energy storage (SMES) s ystem is designed for dynamic stability analysis in multimachine power system, An equivalent current source for the SMES unit is assumed. Th e linear model includes voltage, active power and energy regulators. O n a sample network, eigenanalysis using the QR algorithm shows that th e proposed model increases the damping of slow oscillation modes. Step -response simulations illustrate the positive impact of the SMES regul ator as a power system stabilizer. Performing the component connection method (CCM), the approach is attractive in case one or more addition nal SMES units should be considered.
