考虑复杂工况的光伏组件功率衰减评估方法OA

Regarding the practical operation of photovoltaic(PV)systems,the photo-electron conversion efficiency and degradation rate of PV modules are easily affected by several factors,e.g.,irradiance,humidity,and temperature.Subsequently,an efficient framework for assessing power degradation became the cornerstone for ensuring the levelized cost of energy(LCoE)and conducting a comprehensive analysis of module selection and system design.However,due to the multi-physical field coupling effect in on-field applications,conventional frameworks relying on empirical coefficients or accelerated ageing tests have shown limitations in degradation assessments under complex environmental conditions.To address these issues,a mission-profiles-based power degradation assessment framework for PV modules was proposed.The proposed framework can effectively bridge the degradation model and mission profiles by utilizing adaptive compensation for the impact of environmental coefficients on the module degradation rate,thereby achieving a more reliable assessment of the power degradation of PV modules.
