Impedance Matching for VSC-HVDC and Energy Storage Damping Controllers

Safari Tirtashi, Mohammad Reza LU ; Samuelsson, Olof LU and Svensson, Jörgen LU (2018) In IEEE Transactions on Power Delivery 33(2). p.1016-1017
Abstract

The small-disturbance electro-mechanical dynamics of a power system can be translated to an equivalent circuit model with inductances and capacitances. Damping control of active power in proportion to local frequency as with a VSC-HVDC link or an energy storage then corresponds to introducing a resistor in the circuit model. This letter shows that impedance matching can be used to select resistor value, and equivalently damping controller gain, that gives maximum damping ratio. It is also shown how the concept is employed without a circuit model.
