Design of Hybrid Energy Storage System Model with Multi-input Converter

This paper aims to design and analyze the hybrid energy storage system (HESS) model with multiple input converter (MIC) configurations in simulation as well as real-time models. In the conventional design of HESS systems, each source has its local regulators for better power transfer. Still, in MIC configuration, a single bidirectional regulatory circuit is used to handle every source to get a better power output. In this paper, the HESS model has a renewable source (PV array), a battery unit and an ultracapacitor. All the sources are connected to the MIC converter, and the converter is connected to the AC grid. The purpose of the model is to synchronize the system output to the AC grid as well as use the grid energy for storing energy in the battery as a bidirectional system.
