可再生能源（RES）的高渗透率可能会因其随机性而在主电网中产生稳定性，可靠性和电能质量问题。微电网可以被分析为一种能够保证可再生能源技术产生的能量有控制地注入的解决方案。储能系统在MG中的使用对于确保能量平衡和维持高电能质量起着至关重要的作用。由于现有储能系统的技术局限性，需要采用多种储能技术来满足微电网应用的需求。为了满足上述约束，本文提出了一个超级电容器（SC）和锂离子电池的混合储能系统（HESS）的关联。采用了一种新的控制策略的HESS的控制。逆变器在孤岛和并网模式下的控制采用分层递阶控制。自同步控制确保孤岛和并网模式之间的平稳过渡。在MATLAB/Simulink中对系统进行了仿真。
The high penetration of the Renewable Energy Sources (RES) can create stability, reliability and power quality problems in the main electrical grid due to their stochastic nature. Microgrids can be analysed as a solution capable of guaranteeing a controlled injection of energy generated by the renewable energy technologies. The use of storage system in a MG plays an essential role in order to ensure energy balance and in maintaining high power quality. Due to the technical limitations of the currently available storage systems, it is necessary to use more than one storage technology to satisfy the requirement of microgrid applications. In order to satisfy the above constraints, this paper proposes the association of a supercapacitor (SC) and a lithium ion battery in a Hybrid Energy Storage System (HESS). A novel control strategy is adopted for the control of the HESS. Hierarchical control is used for the control of the inverter in islanding and grid connected mode. Self synchronization control ensures smooth transition between islanded and grid connected modes. Simulation of the system is carried out in MATLAB/Simulink.
