Research on the Stability of Energy Storage Systems for Distributed Photovoltaic Systems Under Smart Grids

Abstract

This paper investigates the impact of energy storage systems on the stability of distributed photovoltaic systems in the context of smart grids. Firstly, the paper delineates the fundamental components and functions of distributed photovoltaic systems. Consequently, the intermittent and fluctuating nature of these phenomena gives rise to questions regarding its effect on the stability of the power grid. In order to address the aforementioned issues, the paper employs the MATLAB/Simulink platform to create a simulation model of a photovoltaic system in collaboration with a lithium battery energy storage system, analysing the influence of the energy storage system on voltage, current, power generation efficiency, and power. The results of the simulation demonstrate that the combination of energy storage systems has the potential to enhance grid stability. The introduction and utilisation of energy storage systems has engendered economic and low-carbon benefits for the power grid. In conclusion, the study explores the prospective evolution of optical storage systems, with a focus on intelligent control methodologies and novel energy management algorithms.
