摘要

This paper presents a review of solar photovoltaic grid-forming control algorithms. Virtual Synchronous Generator Controllers, Controller Systems, Virtual Oscillator Control Algorithms, and Control Algorithms based on Matching are reviewed for grid forming. Solar PV energy storage systems’ grid-forming technology (GFT) is receiving more attention thanks to seamless control algorithms. Nevertheless, a single viewpoint that examines the coordinated GFT for solar and battery systems depending on various structures is lacking. Solar DC battery systems are combined systems where the battery is charged by solar energy, and at the same time, solar photovoltaic panels supply energy to the grid. By offering a thorough analysis of comparable GFT control algorithms for solar dc battery while taking into account dissimilar structures, this research seeks to find the gap. After examining typical solar dc battery system designs, a thorough explanation of the traditional GFT control techniques applied to the Solar dc battery systems is provided. Additionally, coordinated GFT controls in solar Solar dc battery systems are examined based on various Structures, with the common DC bus Structure being recognized as a Structure that is commonly used because of its greater control degrees of freedom and ease of extension. However, the most popular algorithm is the virtual oscillator-based controller. It is reviewed and seen that it is somehow complex to design.
