As a mature power generation technology , solar PV system uses solar cells to directly convert solar energy into electricity.Due to the small voltage and current of a single cell, the PV system generally consists of series and parallel cells, so as to output electricity that meets the requirements.
Large-scale grid-connection of photovoltaic (PV) without active support capability will lead to a significant decrease in system inertia and damping capacity (Zeng et al., 2020).For example, in Hami, Xinjiang, China, the installed capacity of new energy has exceeded 30 % of the system capacity, which has led to signification variations in the power grid frequency as well as

Significant growth in the adoption of battery energy storage systems along with sustained growth in behind-the-meter solar PV systems have contributed to reduced deliveries from utilities to end-use customers.

The use of hybrid energy storage systems (HESS) in renewable energy sources (RES) of photovoltaic (PV) power generation provides many advantages.
Photovoltaic power generation systems generally consist of solar cell arrays, energy storage batteries, protection and control systems, inverters and other equipment. The area of the photovoltaic cell array can be large or small. For example, to set up a square matrix of 10kw, an area of 70 to 80 square meters is required.
However, the CPV cell can only convert a small fraction of the solar energy into electrical power, with the remaining energy being converted into heat. A small portion of this heat is dissipated through natural convection and radiation to the external environment, while the majority is absorbed by the CPV cell''s cooling system.
Due to the inherent instability in the output of photovoltaic arrays, the grid has selective access to small-scale distributed photovoltaic power stations (Saad et al., 2018; Yee and Sirisamphanwong, 2016).Based on this limitation, an off-grid photovoltaic power generation energy storage refrigerator system was designed and implemented.
