Development of an Intelligent Voltage Control System for Bulk Power Systems

“…∆X = S sh •∆U sh (11) where S Vg , S T , and S sh are the sensitivity matrices for the generator terminal voltages, OLTC tap, and shunt capacitors or reactors respectively, and ∆U Vg , ∆U T , and ∆U sh are the control input of the generator terminal voltages, OLTC tap, and shunt capacitors or reactors, respectively. Since the induction process of the sensitivity matrix is rather long and complex, detailed derivation processes and final expressions will be presented in a subsequent paper [18].…”

“…For intelligent voltage control systems, the sensitivity tree-based real-time voltage and reactive power control method was proposed for the first time in Canada [7] in the 1980s. In the 1990s, SEGRE [8] and SETRE [9,10] were proposed in Spain, which are basically hybrid systems using the sensitivity tree-based numerical computation and artificial intelligence method using operators' knowledge [11,12]. However, the detailed numerical modeling and structure of the expert system, such as the knowledge-based, searching-space, and inference technique, have not been reported yet.…”

An Intelligent Voltage Control System for Korean Power Systems

“…In Spain [2,4,7], voltage control systems were successfully applied in the Spanish power system. In addition, several advanced countries are operating voltage and reactive power control systems by taking into account the inherent characteristics of their individual power systems [5,6]. In this paper, we develop and simulate an intelligent control system that provides voltage and reactive power control for Jeju Island in the Korean power system.…”
