Abstract

With the development of wide area network, control information and data of secondary voltage regulation (SVR) systems can be gradually promoted to standard TCP/IP-based network transmission so that the flexibility and reliability of the control system can be enhanced. In terms of the basic principle of networked control system (NCS), this paper presents the networked SVR (NSVR) model with consideration of data transmission delays, packet dropout and time-sequence disorder induced by wide area network transmission. A novel control scheme is proposed based on multi-step prediction and delay compensation, and as a result, favorable control performance and stability of the control system under the network environment can be secured. The simulation results on the New England 39-bus system are presented to illustrate the validity and effectiveness of the proposed NSVR scheme.
