为了能够更广泛地利用可再生能源(RESS)，分布式发电(DGs)在微电网中得到了突出的应用。本研究描述了微电网的设计、建模、实施和运行，其中为教育和研究实验室安装了独立的混合动力系统。RESS的不稳定特性导致DG上的电源兼容性问题。因此，提供从可再生能源到负荷的良好潮流是本文的研究范围。为了满足规定的负荷分布并维持所需的功率水平，功率变流器的设计和运行也是执行微电网的重要部分。对于稳健的微电网结构，提出的控制算法包括可再生能源、电池和负载之间的能量管理系统(EMS)。首先，在MATLAB/SIMULINK环境下对系统进行了建模。此外，还给出了案例研究，以进一步演示模拟系统。在此范围内，不仅提供了特定的负荷分布，而且还对潮流进行了管理和分析，以确保在两种不同的EMS情况下有效和灵活地运行。在实验过程中，还提供了在各种输入和输出条件下对系统进行验证的实时操作。
To enable more wide-scale exploitation of renewable energy sources (RESs), distributed generations (DGs) as in microgrids have gained prominence recently. This study describes the design, modeling, implementation, and operation of a microgrid, in which a standalone hybrid power system has been installed for an education and research laboratory. The unstable nature of RESs results in power compatibility issues on DGs. Therefore, providing a decent power flow from renewables to loads is the scope of this paper. To satisfy defined load profiles and sustain the power with the desired level, the design and operation of power converters are a remarkable part of performing microgrids as well. For a robust microgrid structure, the presented control algorithm includes an energy management system (EMS) between renewables, batteries, and loads. Primarily, modeling of the system has been developed in MATLAB/Simulink environment. Additionally, case studies have been exemplified to further demonstrate the simulated system. Within this scope, certain load profiles not only have been fed but also power flow has been managed and analyzed to ensure effective and flexible operation with two different EMS cases. The real-time operation has been also provided to validate the system under various input and output conditions during a lab course.
