Abstract
The modern power system is evolving towards a new generation of smart grid, with significant benefits from the latest computer-based communication network technologies. Furthermore, as the incremental deployment of phase measurements units (PMUs) and the use of Smart Meters, there will be a substantial increase of the real-time system measurements. Under this trend, event-triggered control (ETC) will play an important role in reducing the communication and computation cost. In this paper, a novel ETC architecture design for load frequency control (LFC) with supplementary adaptive dynamic programming (ADP) is presented. The primary proportional-integral (PI) controller uses different proportional and integral thresholds for updating the actions, while the supplementary ADP controller is updated in an aperiodic manner. A strategy for the parameters calculation is introduced in a systematic way, and theoretical analysis of the ultimate boundedness for the closed-loop event-triggered system is also included. Simulation studies are carried out on one-area and three-area IEEE LFC benchmarks, and the results demonstrate the efficiency and effectiveness of the proposed design.
