Abstract

Inverter-based generations can play a vital role in power system restoration, especially for aiding system recovery through black start capability, rendering them crucial in contemporary grid resilience strategies. This paper presents a novel chattering-free fixed-time sliding mode power synchronization control (FSMPSC) approach specifically designed to enhance such black start capability of voltage-controlled (VC) inverters. The key aim of this controller is to enhance the robustness of the closed-loop system, facilitating the seamless integration of the inverter using grid-forming (GFM) control with the utility grid under various grid conditions. Remarkably, this integration is achieved without needing an additional synchronization unit, such as a phase-locked loop (PLL). The proposed controller significantly improves grid synchronization, allowing for a smooth transition of the inverter from off-grid to grid-connected modes while maintaining voltage source characteristics. The fixed-time stability analysis for the closed-loop system under the proposed controller is analytically derived by selecting an appropriate candidate Lyapunov function. This analysis facilitates the definition of an advanced form of sliding surface and control law, ensuring chattering minimization without compromising the fast response and robustness of the proposed controller. The real-time viability of the controller is authenticated by the experimental tests conducted in a hardware-in-the-loop (HIL) setup.

无抖振定时滑模功率同步控制的压控逆变器黑启动解决方案

基于逆变器的发电机组在电力系统恢复中发挥着至关重要的作用，特别是通过黑启动能力帮助系统恢复，使其在当代电网恢复策略中至关重要。本文提出了一种新的无抖振固定时间滑模功率同步控制（FSMPSC）方法，专门用于提高压控（VC）逆变器的黑启动能力。该控制器的主要目的是增强闭环系统的鲁棒性，促进逆变器在各种电网条件下与电网的无缝集成。值得注意的是，这种集成不需要额外的同步单元，例如锁相环（PLL）。所提出的控制器显著改善了电网同步，允许逆变器从离网到并网模式的平稳过渡，同时保持电压源特性。通过选择合适的候选Lyapunov函数，解析导出了该控制器下闭环系统的定时稳定性分析。这种分析有助于定义一种高级形式的滑动面和控制律，在不影响所提出控制器的快速响应和鲁棒性的情况下确保抖振最小化。在硬件在环（HIL）装置中进行了实验测试，验证了控制器的实时可行性。
