“…Secondary voltage control (SVC), the structure of which is shown in Figure 1, is able to reduce the possibility of voltage instability. Indeed, a lot of approaches for the design of secondary voltage controllers have been reported in the literature , some of which have been proven to be effective methods to guarantee the stability and security operation in some electric power industries [6][7][8][9][10][11][12][13][14][15]. The basic operation principle of the SVC is summarized in the following: when voltage violations occur at certain key load buses which are designated as pilot nodes, the SVC will be enabled to keep the scheduled voltage profiles by optimal coordinated control of reactive power sources.…”

“…In recent years, many research studies have focused on the secondary level for the achievement of the stability and security operation in smart grids . The secondary voltage control (SVC) method was first established in France [6], and has been applied in several countries, such as some European countries [6][7][8][9][10], Brazil [11], South Africa [12], US [13,14], and China [15].…”

This paper proposes a new voltage control methodology using the particle swarm optimization (PSO) technique for smart grid loadability enhancement. The goal of this paper is to achieve reliable and efficient voltage profile/stability regulation in power grids. This methodology is based on the decouple power flow equations and the worst-case design technique. Specifically, the secondary voltage control (SVC) problem is formulated as an L-infinity norm minimization problem which considers overall load voltage deviations in electrical power systems as an objective model, and the PSO technique is employed to determine a robust control action which aims to improve voltage profile and to enlarge transmission grid loadability by optimal coordinated control of VAR sources. The methodology was successfully tested on several IEEE benchmark systems.

Keeping voltages of all buses within acceptable bounds is very important for power system operations. This paper presents an approach for optimal coordination of static var compensators (SVCs), transformer under load tap changers (ULTCs) and load shedding to improve voltage performance following large disturbances. The approach is based on model predictive control (MPC) with a decreasing control horizon. The MPC formulation leads to a mixed integer quadratic programming (MIQP) problem, since both continuous and discrete controls are considered. Trajectory sensitivities are used to evaluate the effect of controllers on voltage performance. The iterative optimization process of MPC helps ensure that errors introduced due to any model inaccuracies and approximations are minimized. The MPC based coordination of these controllers is applied to a modified WECC system to enhance the voltage performance and to a modified 39-bus New England system to prevent voltage collapse.
