摘要
为解决当前在配电网-微电网协同(简称配微协同)背景下,末端保供型公共交直流混合微电网缺乏标准化测试算例平台的问题,基于实际油气井站微电网构建了一个具备代表性的交直流混合微电网典型算例平台D&U-MG-ACDC24。该平台充分考虑交直流混联结构下多类型源-荷-储的动态耦合特性,引入互联变流器控制、柔性功率交换机制等关键运行要素,构建了包含上层经济调度与下层暂态响应的双时间尺度建模框架。针对交直流混合微电网在源荷波动、配电网功率支撑受限以及本地故障动态响应等典型运行场景下的关键问题,提炼出若干具有代表性的配微协同场景,并基于MATLAB/Simulink平台构建了相应的控制优化仿真模型。仿真结果表明,所提测试算例不仅具备较强的场景通用性与动态还原能力,还能有效支撑多类控制算法验证与策略对比,为交直流混合微电网的标准化测试体系建设提供了参考,也为源-网-荷-储多元耦合系统的协同优化与稳定控制研究提供了可靠支撑。
To address the lack of standardized test cases for distribution–microgrid coordination scenarios,this paper proposes a benchmark platform,D&U-MG-ACDC24,specifically designed for end-side power supply-oriented public AC/DC hybrid microgrid,based on an actual oil and gas station microgrid.The platform fully considers the dynamic coupling characteristics of multi-type source-load-storage systems under the AC/DC hybrid topology,incorporating key operational elements such as interlinking converter control and flexible power exchange mechanisms.A dual-timescale modeling framework is established,which integrates upperlevel economic dispatch with lower-level transient response dynamics.Focusing on critical issues in typical operation scenarios—including source-load fluctuations,limited power support from the distribution network,and local fault responses—this study extracts several representative coordination cases and develops corresponding control-optimization simulation models in MATLAB/Simulink.Simulation results demonstrate that the proposed test case exhibits strong generality and fidelity in dynamic behavior,and is capable of supporting diverse control algorithm validation and strategy comparison.The benchmark contributes to the standardization of AC/DC hybrid microgrid testing systems and offers a reliable foundation for the coordinated optimization and stability analysis of complex source-grid-load-storage integrated systems.
