光伏微电网的稳定性评估是确保系统可靠运行的关键,然而光伏微电网中存在着太阳形与光学误差等不确定因素给系统稳定性带来挑战。提出了一种基于太阳形与光学误差的光伏微电网稳定性评估模型,旨在准确评估系统的稳定性,并为系统的优化提供参考。首先建立基于真实太阳形状的集中磁通分布模型。然后结合雾度、光学误差、阴影和遮挡效应等光学误差因素建立光伏微电网稳定性评估模型。最后,本模型在实际光伏微电网中进行了验证,通过收集系统运行数据和太阳形、光学误差数据,将其输入到模型中进行评估。实验结果表明,该模型能够准确评估光伏微电网的稳定性,通过调整系统组件、优化光学系统和调整运行策略等方式,可以显著提高光伏微电网的稳定性和可靠性。

The stability evaluation of photovoltaic microgrids is crucial to ensure the reliable operation of the system.However,there are uncertainties such as solar shape and optical errors in photovoltaic microgrids that pose challenges to system stability.This article proposes a stability evaluation model for photovoltaic microgrids based on solar shape and optical error,aiming to accurately evaluate the stability of the system and provide reference for system optimization.Firstly,a centralized magnetic flux distribution model based on the true shape of the sun is established.Then,a stability evaluation model for photovoltaic microgrids is established by combining optical error factors such as haze,optical error,shadow,and occlusion effects.Finally,this model was validated in an actual photovoltaic microgrid by collecting system operation data and solar shape and optical error data,which were input into the model for evaluation.The experimental results show that the model can accurately evaluate the stability of photovoltaic microgrids.By adjusting system components,optimizing optical systems,and adjusting operating strategies,the stability and reliability of photovoltaic microgrids can be significantly improved.
