光伏发电特性与加热电阻的关系研究
Research on the Relationship between the Characteristics of Photovoltaic Power Generation and Heating Resistance
摘要: 随着光伏发电的快速发展，其间歇性与波动性导致的“弃光”现象日益突出。为提高光伏电力消纳效率，本研究通过实验探究光伏发电特性与负载电阻的关系，分析不同电阻对光伏电压、电流及功率的影响，明确最大功率点对应的电阻特性。结果表明：光伏电压随电阻增大而升高，电流随电阻呈现三段式变化规律，功率存在临界值且随太阳辐照度减弱向高阻方向偏移。研究为动态调整电阻以优化光伏系统效率提供了实验依据。
Abstract: With the rapid development of photovoltaic power generation, the phenomenon of “abandoned light” caused by its intermittency and volatility has become increasingly prominent. In order to improve the consumption efficiency of photovoltaic power, this study explores the relationship between the characteristics of photovoltaic power generation and the load resistance through experiments, analyzes the impacts of different resistances on the photovoltaic voltage, current, and power, and clarifies the resistance characteristics corresponding to the maximum power point. The results show that the photovoltaic voltage increases with the increase of the resistance, the current shows a three-stage change law with the resistance, and the power has a critical value and shifts towards the high-resistance direction as the solar irradiance weakens. This study provides an experimental basis for dynamically adjusting the resistance to optimize the efficiency of the photovoltaic system.
