Abstract

Renewable energy sources (RES) are widely needed because of the growing population and increased demand for energy resources. RES are also inexpensive, abundant, and free of pollution. An energy storage system (ESS) is crucial for meeting the load requirement. Because of its high energy density, BESS is generally favored. In temporary situations, it reacts slowly to abrupt changes. An energy storage system (ESS) is crucial for meeting the load requirement. Because of its high energy density, BESS is generally favored. In temporary situations, it reacts slowly to abrupt changes. Therefore, in order to build a HESS, an ESS with a high power density, such as a super capacitor, needs to be combined with a battery. The ESS and PV array are connected by a 48 V DC connector. In this work, as the solar output power rises, the HESS uses the extra power to keep the load's power supply constant and returns energy to the load when the PV is unable to meet the load's demand. An integrated control approach is suggested, which proficiently produces the bidirectional converter's switching pulses.The voltage control loop generates the entire current that goes to the HESS. In addition to designing the existing control loops, stability analysis is done. Bode plots are employed in HESS stability testing. The outcomes are encouraging, and the controller effectively shares power between the SC and battery and restores the DC link voltage. With the suggested controller, it is discovered that HESS performs well in providing average power for extended periods of time and managing transient situations for brief periods of time.
