Event-Triggered Adaptive Dynamic Programming of Load Frequency Control

Due to the super rapid development of computer communication network technology, the power system is developing more and more rapidly. In addition, with the increase of measuring instruments and the use of intelligent instruments, when the measurement data of Remote Terminal Unit (RTU) is transmitted to the control center, the communication burden will increase. Therefore, introduction of event-triggered control can save communication resources and reduce the network burden. This paper put forward this design method of event-triggered Adaptive Dynamic Programming (ADP) Load Frequency Control (LFC). The controller adopts aperiodic update mode and ADP evaluation-execution module to update the control law. ADP is implemented by two three-layer artificial neural networks. Simulation study on a one-area IEEE LFC system proves the correctness of the theoretical analysis.
