“双碳”背下光伏电池MPPT控制技术的优化

Optimization of MPPT Control Technology for Photovoltaic Cells under the Background of"Dual-Carbon"

随着经济的不断发展,当代社会对新能源的需求日益增长。然而,过度开采天然矿产等能源的做法带来了层出不穷的环境问题,并导致石油、天然气等水资源稀缺以及煤化工的消耗严重。“双碳”目标的提出,核心在于实现能源低碳转型,其中,太阳能被视为新能源中最重要的基础能源。太阳能作为一种辐射能,可通过转换装置成为人类可利用的电能。光伏电池即是一种可将太阳能转换为电能的装置。据研究分析发现,光伏电池的标称输出功率会受到周围环境因素影响,为提高光伏电池转换效率,可对环境因素进行研究。本研究旨在利用MATLAB构建一个太阳能电池最大功率监测与跟踪系统,采用扰动观测方法为研究依据,对光伏阵列进行最大功率跟踪,优化光伏电池MPPT控制技术,进一步提高太阳能电池的标称输出功率,提高光伏电池转换效率,促进绿色低碳协同发展。

With the continuous development of the economy,the demand for new energy in contemporary society is increasing.However,the overexploitation of natural minerals and other energy sources has led to a number of environmental problems,as well as the scarcity of water resources such as oil and natural gas,as well as the serious consumption of coal chemicals.The core of the"dual carbon"goal is to achieve low-carbon energy transformation,in which solar energy is regarded as the most important basic energy source in new energy.As a radiant energy,solar energy can be used by humans through conversion devices.A photovoltaic cell is a device that converts solar energy into electricity.According to the research analysis,the nominal output power of photovoltaic cells will be affected by the surrounding environmental factors,and the environmental factors can be studied in order to improve the conversion efficiency of photovoltaic cells.The purpose of this study is to construct a monitoring and tracking system for the maximum power of solar cells using MATLAB,and to use the disturbance observation method as the research basis to track the maximum power of photovoltaic arrays,optimize the MPPT control technology of photovoltaic cells,further improve the nominal output power of solar cells,improve the conversion efficiency of photovoltaic cells,and promote the coordinated development of green and low-carbon.
