Abstract

The transformation towards renewable and sustainable energy, as well as the digitalization of energy, has promoted the development of the power system towards miniaturization, decentralization, and intelligence. As a solution, a battery-directly-connected DC microgrid has been proposed in previous studies for autonomous and decentralized coordination control (ADCC). We constructed a testbed of the battery directly connected DC-microgrid in our university campus which has been operating stably for more than one year. This study experimentally verifies the feasibility of the battery-directly-connected DC microgrid, and the process of autonomous, decentralized, and coordinated energy distribution between the distributed small batteries through power loading experiments. In addition, a simulator for analyzing the behavior of the DC microgrid test platform is built in MATLAB/Simulink, and its accuracy is verified based on an energy flow analysis, revealing its potential for cyber-physical-system (CPS) construction.

电池直连直流微电网系统的实验验证与仿真分析

可再生能源和可持续能源的转型，以及能源的数字化，推动了电力系统向小型化、分散化、智能化的方向发展。作为一种解决方案，在以前的研究中提出了电池直连直流微电网的自治和分散协调控制(ADCC)。我们在大学校园搭建了电池直连直流微电网试验台，已稳定运行一年多。本研究通过功率负荷实验验证了电池直连直流微电网的可行性，以及分布式小电池之间自主、分散、协调的能量分配过程。此外，利用MATLAB/Simulink搭建了直流微电网测试平台的仿真平台，并基于能量流分析验证了其准确性，揭示了其在网络物理系统(CPS)构建中的潜力。
