Periodic event-triggered control of flywheel energy storage matrix systems for wind farms

Abstract

Flywheel energy storage plays a significant role in improving the reliability and efficiency of wind farm operations, in recent years. In order to reduce the communication burden, this study proposes a distributed algorithm based on the event triggered to coordinate the operation of wind farm and flywheel energy storage matrix system (FESMS). Different from the traditional sampling mechanism, a periodic sampling-based event-triggered condition, which is based on the disagreement vector and the measurement error, is proposed for the FESMS dispatch problem. Furthermore, a self-triggered method is also studied as well considering the periodic sampling case. The algorithm achieves ratio consensus in a balanced directed graph topology. By simulation, the effectiveness of the proposed algorithm is verified.
