摘要
The main framework of a new adaptive coordinated voltage control (ACVC) has been presented and published in our previous paper. ACVC is realized based on knowledge exploration from nondominated solution sets of multiobjective optimization. Knowledge is prepared and accumulated from offline training and online learning processes. This facilitates fast responses. An important basic work is to further study knowledge sensitivity to power system characteristics such that the efficiency of ACVC for various dynamics of power systems can be improved. A comparative study and discussion of power system scale, allocation of control devices, operational point variations, and severity of emergencies are presented in this paper. An improved form of knowledge is also proposed for ACVC based on these discussions. Numerical simulations on the IEEE 39-bus, 118-bus, and 300-bus power systems are performed for comparison and discussion.
