This paper proposes a centralized multi-plant reactive power and voltage controller to support voltage control in the interconnected onshore power system. This controller utilizes a hierarchical control structure consisting of a master controller and multiple slave controllers. To validate the proposed method, a realistic planning case of the New York State grid is created for the year 2035, in which nearly 9,500 MW AC or DC connected offshore wind resources are modeled. The performance of the proposed controller is analyzed in the large-scale model under three realistic disturbance scenarios: generator loss, load ramps, and load steps. Results demonstrate how the controller can adequately perform under disturbances to share reactive support proportionally among plants based on their ratings and improve grid voltage stability margins.
