“…The proposed design is compared with GPIO-based traditional time-triggered mechanism, static ETM, and dynamic ETM (23), and it is found that the proposed dynamic ETM (29) saves channel constraints more efficiently. The frequency deviation is also found to be better compared with recently reported works [8,10,11,14,15] with effective utilization of channels. The proposed design exhibited excellent F I G U R E 1 5 Load disturbance and frequency deviations for standard IEEE 39 bus system disturbance rejection capability compared to recent works [32][33][34][35].…”

“…The error analysis in terms of integral square error (ISE), integral absolute error (IAE), and integral time absolute error (ITAE) is computed and is found to be lesser than the reported works (see Table 5). The proposed work is also compared with few recently reported works in the field of ETC in power systems [8,10,11,14,15]. The proposed control scheme not only stabilizes the frequency more effectively under load disturbance (see Figure 13A) but also saves larger communication constraints (see Figure 13B and Table 6).…”

“…An optimal proportional-integral-derivative (PID) with a filter controller for frequency regulation in power systems considering effective utilization of network resources is reported in Dahiya et al [14]. An observer-based dynamic event-triggered scheme to improve the communication constraints more efficiently by adding an extra exponential term in the event condition is reported in Wu et al [15]. The controllers often follow their interests through noncooperative operations; that is, each controller is structured to minimize its cost function.…”

The article addresses a generalized proportional-integral observer (GPIO)based event-triggered control (ETC) for load frequency problems in power systems with wind energy integration. The concept of static event-triggered mechanism (ETM) with a fixed threshold parameter may be unreasonable in some engineering applications where the transmission rates are time varying as in the case with power systems. Therefore, in this work, a dynamic ETM is designed to dynamically adjust the threshold parameters over time to reflect the time-varying transmission rates. The unmatched uncertainties are suppressed via high-gain design while the external disturbance (wind speed) is estimated and attenuated by the GPIO-based ETC. The proposed design ensures frequency and tie-line power stabilization and saves the computational and communication resources more effectively than recently reported works in the field. The hybrid closed-loop system's global bounded stability is theoretically proved and verified by simulation in three-area interconnected power systems.

“…Hence, an SFC scheme with low information transmission is the top priority for MG control. To this end, some networked control methods, such as event-triggered control [25][26][27][28] and sampled-data control [29], have become the mainstream direction of current research. The unifying characteristics of the above-mentioned networked control methods are obvious, that is, digital and discrete.…”

The popularity of renewable energy distributed generation has increased for environmental and convenient concerns. However, the occurrence of the above situation will cause the communication resources of the microgrid to be rapidly consumed to maintain the frequency stability of the system. In this work, a novel event‐triggered scheme is developed to ameliorate the present communication networks of island microgrid with communication delay. Combining the newly constructed Lyapunov–Krasovskii functional and the convex combinatorial method, the asymptotic stability of a typical microgrid is demonstrated. Moreover, taking dynamic switching system into account, the two‐part proof is completed independently. Then, a positive inter‐execution time lower bound is implemented to guarantee that there is no Zeno behaviour. Finally, the numerical simulation results are compared with other sampling methods in different scenarios. It indicates that the proposed scheme is superior to other types of scheme in frequency response performance and communication burden.
