摘要
在确定固定式并网光伏阵列最佳倾角时,设计人员要兼顾考虑年发电量和光照辐射均匀性两方面的因素。建立了以倾斜表面年辐照量最大和辐射累积偏差最小的多目标光伏阵列最佳倾角模型。运用基于目标满意度和整体协调度的交互式多目标决策方法对所建模型进行了求解,实时将决策者的主观意愿与系统进行交互,计算效率高。算例证明了所建模型的合理性和交互式多目标决策方法的可靠性。
During the determination of optimal tilt angle of fixed grid-connected photovoltaic （PV） array, two factors, i.e., the annual generated energy and uniformity of illumination radiation, should be considered simultaneously. A multi-objective optimal tilt angle of PV array model, in which the maximum annual irradiation amount and the minimum cumulative departure of the irradiation are taken as objectives, is established. The established model is solved by interactive objective decision-making method based on satisfaction degree of objectives and overall coordination degree to interact the decision-maker’s subjective wishes with the system in real-time, so the computational efficiency is high. The reasonability of the established model and the reliability of the proposed interactive multi-objective decision-making are validated by calculation example.
