Abstract

Microgrids are small-scale power systems destined to supply isolated villages and optimum utilization of renewable energies. For this reason, this paper presents a DC-MG of 150 Kwp to feed an island village. The configuration of the proposed system consists of four interconnected sub-sections supplied by the centralized unit through PV and Wind Distributed Energy Resources DERs, in addition to the supercapacitor storage device. In the other hand, internal batteries of each sub-section cover its load demand separately, where electrical and chemical storage devices can be advantageous hybrid energy storage system HESS for the system. Thus, the control structure of the DC-MG is based on current hysteresis method to assure the charge/discharge operation and the stability of the DC-bus voltage, then a proposed management strategy to manage the shared energy of the DCMG system. The system behavior is tested under variable parameters and conditions using Matlab/Simulink.

提出了一种基于分散直流微电网的孤立社区PV-WT-HESS能源管理方法

微电网是一种小型电力系统，旨在为偏远的村庄提供电力，并使可再生能源得到最佳利用。为此，本文提出了一台150kwp的DC-MG供一个海岛村庄使用。拟议系统的配置包括四个相互连接的子部分，由集中单元通过光伏和风能分布式能源DERs提供，此外还有超级电容器存储设备。另一方面，各子段内部蓄电池分别覆盖其负载需求，其中电气和化学存储装置可为系统提供有利的混合储能系统HESS。在此基础上，提出了基于电流滞回法的DC-MG控制结构，以保证充放电运行和直流母线电压的稳定，并提出了一种管理策略来管理DCMG系统的共享能量。利用Matlab/Simulink对系统在变参数和条件下的性能进行了测试。
