“…[13,14] TENG's good electricity generation performances under low-frequency motion and its ability to capture wind-induced vibration make it an excellent candidate for power generation in power transmission lines with lowfrequency, large-amplitude motion. [15][16][17] However, any new TENG design for such a purpose must not add any additional burden to the power transmission lines. [18,19] To address this challenge, an anti-self-excited oscillation triboelectric nanogenerator (AO-TENG) is proposed in this work design.…”

To ensure the reliability and stability of long‐distance power transmission, it is necessary to monitor the health status of power transmission lines and the power grid environment. However, the utility of overmuch sensors could lead to adverse issues such as short battery life and susceptibility to environmental factors. To address this, an anti‐self‐excited oscillation triboelectric nanogenerator was proposed in this study, In the AO‐TENG structure, the original spacing rods of the power transmission line are modified. In the event of aeolian vibration in the power transmission line, the AO‐TENG generates electricity via cohesive work between the spring and the additional weight block, driving the TENG. Under specific conditions (300 g additional weight, 2.0 Hz vibration frequency, and 80 mm amplitude), the TENG can produce 125 μW of power. Additionally, an anti‐self‐limited power management circuit is used to process AO‐TENG power generation by utilizing the anti‐self‐excited characteristics of the capacitor. This prevents excessive impact voltage from damaging the back‐end circuit, and the capacitor plays an important role in voltage drop. Solve the problem that the high output voltage of the triboelectric nanogenerator is difficult to supply power to commercial sensors. Due to the integration of IoT, big data, information technology, sensor technology, and clean energy technology, the main difference between a smart grid and a conventional power grid is that a stable power supply method for distributed sensors in the power grid is required to transmit the monitored information to the terminal. This study introduces a new design solution to promote smart grids, which guarantees stable operation of distributed sensor nodes on such grids. The combination of TENG and smart grid also paves the way for clean, environmentally‐friendly, and low‐carbon goals, offering a reliable basis for smart grid operations.This article is protected by copyright.
