摘要

本文提出了一种由混合储能系统(HESS)组成的直流微电网(DCMG)运行的控制技术。针对所提出的控制方案，在孤岛模式下对DCMG进行了多种工况的动态性能分析。在DCMG中，HESS由电池储能系统(BESS)和氢储能系统(h2ss)组成。采用双向dc-dc变换器和dc-dc降压变换器分别将BESS和h2ss集成到DCMG中。在孤岛模式下，在DCMG功率失配时，所提出的控制方案允许控制BESS的运行以满足功率失配，并且BESS容量之外的剩余发电功率存储在h2ss中。所提出的控制方案旨在对所有情况下DCMG的功率和额定电压进行管理。

PERFORMANCE ANALYSIS OF HYBRID ENERGY STORAGE SYSTEM-BASED DC MICROGRID FOR A DEVELOPED CONTROL TECHNIQUE

This work proposes a control technique for the operation of the proposed DC microgrid (DCMG) consisting of a Hybrid Energy Storage System (HESS). The dynamic performance analysis of DCMG for the developed control scheme has been carried out in islanded mode under several operating conditions. In DCMG, the HESS consists of Battery Energy Storage System (BESS) and Hydrogen Storage System (H 2 SS). The bidirectional dc-dc converter and dc-dc buck converter have been used to integrate BESS and H 2 SS, respectively, into DCMG. In the islanded mode, during power mismatch in DCMG, the proposed control scheme allows to control the operation of BESS to fulﬁl the power mismatch, and beyond the capacity of BESS, the surplus generated power is stored in the H 2 SS. The proposed control scheme is aimed to manage the power and rated voltage of DCMG for all cases.
