For grid storage applications, supercapacitor hybrid systems aim to provide rapid response capabilities for frequency regulation, voltage support, and grid stabilization while maintaining sufficient energy capacity for longer-duration services. . This study focuses on hybrid energy stor-age technology combining supercapacitors and batteries in parallel, providing an in-depth analysis of their performance characteristics. Batteries suffer from drawbacks such as poor low-temperature performance, low energy density, and low charge-discharge. . This paper proposes a hybrid synchronization control modular multilevel converter-based hybrid energy storage system (HSC-MMC-HESS) that innovatively integrates battery units within MMC submodules (SMs) while connecting a supercapacitor (SC) to the DC bus. Supercapacitors reduce the stress on the battery, extending its lifespan. The study utilizes a two-branch equivalent circuit model for the supercapacitor. .
