分布式能源（DER）的急剧增加导致全球配电系统的运行面临挑战。虽然在市场上和文献中有几种用于电网监测和控制的解决方案，但本研究是第一次通过提供模块化可配置的统一硬件和软件架构来监督电网。控制算法使用符合IEC 61850 - 7 - 3和IEC 61850 - 7 - 4的数据模型进行配置。新的系统架构是一种便携式，模块化和灵活的架构，将智能电网控制功能聚合到标准化的硬件平台上，强调硬件独立性的需求。中央控制器包含多个智能电网控制功能，各种现场设备分布在配电网上。本文论述了不同的真实的世界的配电网的模拟上的真实的时间仿真器（RTS）和实验验证的控制算法。协调电压控制（CVC）和最优潮流（OPF）等智能电网控制功能已在德国电网上进行了实验验证。当中央控制器执行CVC时，将电网动态与OPF实现进行比较。文中给出了每种控制方法的实验结果、优点和挑战。结果还表明，在网格的行为时，控制参数的变化。本文还表明，算法和控制参数的选择取决于配电网的复杂性和系统运营商的个人需求。结果表明，这种通用的配电自动化解决方案的潜力，为世界各地的系统运营商。
The drastic increase in distributed energy resources (DERs) leads to challenges in the operation of distribution systems worldwide. While several solutions for grid monitoring and control are available on the market and in literature, this research is the first of its kind aiming to supervise the grid by providing a modular configurable unified hardware and software architecture. The control algorithms are configured using data models according to IEC 61850‐7‐3 and IEC 61850‐7‐4. The novel system architecture is a portable, modular and flexible architecture that aggregates smart grid control functions onto a standardised hardware platform, emphasising the need for hardware independence. The central controller contains several smart grid control functions and the various field devices are distributed across the distribution grid. This paper deals with the simulation of different real‐world distribution grids on the Real‐Time Simulator (RTS) and experimental verification of the control algorithms. Smart grid control functions such as Coordinated Voltage Control (CVC) and Optimal Power Flow (OPF) are experimentally verified on a German grid. The grid dynamics are compared when the central controller executes the CVC against the OPF implementations. The experimental results, advantages and challenges of each control are presented here. The results also showed the variation in grid behaviour when the control parameters were varied. The paper also shows that the algorithm and the choice of the control parameters depend upon the distribution grid's complexity and the system operator's individual needs. The results illustrate the potential of such a universal distribution automation solution for system operators worldwide.
