The congest in an open communication system may cause the failure of the load frequency control (LFC) scheme in the power system. Furthermore, the increase of wind power penetration degrades the stability of the LFC scheme. To addressing these two issues, this paper analysis the stability of the LFC schemes with both the Bernoulli model and the Gilbert-Elliott model packet losses based on the Markov jump system. The effect of wind penetration on the stability of the LFC schemes also discussed as the inertia reduction. Moreover, the combined action of packet losses and inertia reduction is discussed both in theoretical. Then, a resilient event-triggered LFC scheme is proposed to deal with packet losses and wind penetration. Simulation results with different scale of power systems are given to validate the proposed LFC scheme.INDEX TERMS Load frequency control, wind power, packet losses, inertia reduction, Markov jump linear system. I. INTRODUCTION1 L OAD frequency control (LFC) scheme is an essetial and 2 commonly used control system of the modern power 3 systems. It helps to maintain the system frequency at the 4 desired level subject to the disturbances [1]. Modern power 5 systems are equipped with wide-area measurement systems, 6 enabling the control center to receive remote signals, and 7 hence to improve the closed-loop performances of the whole system [2]. With the integration of power systems and com-9 munication infrastructures, the power system has become to a 10 large-scale cyber-physical system [3], [4]. Though such evo-11 lution brings opportunities, the twofold challenges remain, 12 namely the communication perspective and physical system 13 perspective.

“…• Secondly, the increasing deployment of renewable energy introduces additional disturbances [20], [21] to the power system frequency [22]. On the one hand, the fluctuations and intermittency of the renewable sources make the renewable power plants less controllable than the conventional thermal units [23], [24].…”

In this paper, a full-order terminal sliding-mode control method is proposed for the rectifier side and the inverter side of the soft open point (SOP). The rectifier-side DC voltage control system consists of the voltage- and current-loops with controllers which are designed using full-order sliding-mode (FOSM) to enhance the dynamic performances and anti-disturbance. The integral type virtual control signal without chattering is designed to compensate for the unmatched uncertainties including external disturbances and some parameter perturbations. The full-order terminal sliding-mode (FOTSM) controller for the current-loop can force the current response to track its reference in finite time. The inverter side power control system is designed to regulate the power. The FOTSM controller for the power-loop ensures the power-tracking accuracy under a disturbed condition. Finally, the simulations demonstrate the effectiveness of the proposed controllers for the rectifier and inverter sides in the soft open point (SOP).

Aiming at the problem of long-timescale prediction deviation in the distribution network, a fast regulation strategy of cloud-edge coordination based on an intelligent transformer supply zones edge consistency algorithm is proposed. The cloud makes the global initial optimal allocation to the edge transformer supply zone clusters, and then the cluster makes the secondary collaborative optimal allocation to the edge zones. A fast power interaction model within a cluster based on a consensus algorithm is established, and the micro-increase rate of dispatching cost is used as the consistency variable so that the cluster adjustment amount is optimally allocated to each transformer supply zone, and the total dispatch cost of all transformer supply zones is minimized. The simulation example verifies the effectiveness of the cloud-edge collaborative fast control strategy based on the intelligent station cluster edge consensus algorithm in this article.
