An Adaptive Coordinated Secondary Voltage Control with PMU Data

This paper presents a novel adaptive coordinated secondary voltage control (SVC) approach to enhance the power grid voltage stability with synchronized phasor measurements. The proposed SVC design method is based on a nonlinear data-driven control algorithm which named model-free adaptive control (MFAC). The MFAC algorithm is improved to meet the SVC coordination design requirements. Parameter settings of the improved algorithm are also analyzed to ensure the entire system stability. Efficiency of the proposed MFAC-SVC were verified on the New England system under different disturbances.
