“…Two-port SOP can be considered as a back-to-back voltage source converter (VSC) consisting of a rectifier-side VSC, an inverter-side VSC, and a DC capacitor (Wu et al, 2018). The mathematical model of SOP is a non-linear system with solid coupling characteristics, including the uncertainty of external disturbances and parameter perturbations, which significantly complicates the controller design (Huo et al, 2021;Liang et al, 2022). Some traditional control methods of SOP are widely used in SOP systems, including proportional-integral (PI) control, model predictive control (MPC), and droop control (Cao et al, 2016;Cai et al, 2018;Falkowski and Sikorski, 2018;Li et al, 2020;Zhang et al, 2021).…”

This paper proposes an extended state observer-based ultra-local model-free three-vector predictive control method for Soft Open Point (SOP). First, the Ultra-Local Model-Free Predictive Control (ULMFPC) method is proposed to improve the robustness of the system, which only uses the input and output of the outer-loop, and any other parameters are not involved. Second, considering parameter perturbations and external disturbances in the SOP system, an expansion state observer (ESO) is established to observe the SOP system’s total perturbations and the perturbations are compensated in real-time to improve the system. Third, to solve the problem of significant current harmonics in traditional model predictive control (MPC), a three-vector MPC method (TV-MPC) is adopted to reduce the total harmonic distortion rate (THD) of the current. Finally, it is verified by simulation that the proposed method can effectively reduce the current harmonics of the SOP system, rate value setting time, and improve the dynamic performance effectively. When perturbations occur in the system, the proposed method can improve the anti-interference and robustness of the system.

“…An effective planning must be conducted prior to undesirable incidents to prepare for and lessen the impact of upcoming disasters. The disaster-specific planning may include hardening schemes [12], resource allocation [13], [14], prediction [15], repair crews [16], and switch design [17], [18].…”

“…Hardening of distribution networks refers to making the infrastructure sturdier and consequently more durable to failure, so that serious damages due to natural disasters can be minimized, and the restoration time can be reduced accordingly [12]. The system recovery capability can be improved by availability of spare and reliable resources, and their preevent allocation [14].…”

Microgrid formation is a promising solution to enhance resiliency of distribution networks. The self-adequacy feature of a microgrid enables continuity of power supply through distributed generation (DG) units during severe faults and natural disasters. In this paper, different methods commonly used to partition a distribution network into multiple microgrids are presented, including the graph theory, heuristic rulebased algorithm, cluster-based technique, and mixed integer programming. Advantages and disadvantages of these techniques and future research directions are presented. This review provides an excellent summary on service restoration through micrgrid formation, and offers a valuable reference for researchers working on grid modernization of distribution networks.

“…The other VSCs work in P-Q mode to realize the power exchange of several AC feeders [8]. The mathematical model of the SOP is a class of nonlinear system with matched and unmatched uncertainties [9]. The uncertainties contain external disturbance and parameter perturbation, which bring a huge challenge to the controller design [10].…”

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).
