VL - 25 IS - 2 SE - Electrical and Electronic Engineering DO - 10.14483/23448393.15741 UR - https://revistas.udistrital.edu.co/index.php/reving/article/view/15741 SP - 194-211 AB - <p><strong>Context:</strong> Thanks to the low emissions of CO2 generated by electric systems, those solutions have an<br>increased attention from industry and academia. However, the electrical storage systems required in a<br>large amount of applications must to have both high energy and power densities.</p><p><strong>Method:</strong> To meet those requirements, this paper proposes an active hybrid energy storage system<br>(HESS), which is formed by a battery, i.e. the device with high energy density, and a capacitor, i.e. the device with high power capability. The proposed power system also protects the battery by limiting the current derivative.</p><p><strong>Results: </strong>Two sliding-mode controllers (SMC) are designed to regulate both the battery current and the load voltage. The design process guarantees the global stability and safe battery operation.</p><p><strong>Conclusions:</strong> The controller avoids the battery degradation caused by the high-frequency current components since the capacitor assumes those components demanded by the load profile.</p> ER -
