Summary:
The aim of the secondary voltage control is to maintain voltage magnitudes of several load buses, which have been selected as pilot buses, at their optimal values imposed by the tertiary voltage control. In this paper a comprehensive formulation of the secondary voltage control is presented. Centralized control matrices for an optimal proportional integral control are obtained by the minimization of a performance index. Conditions to achieve a stable closed-loop in a decentralized control scheme are stated. A systematic methodology for selecting pilot buses and for dividing the system in decentralized control areas is presented. The differences between centralized and decentralized control schemes are analyzed in a case study based on the New England 39 bus system.
