The output characteristics of a photovoltaic (PV) array are highly non-linear. Therefore, an accurate andefficient PV model is required to study and analyze the operation of PV system in the changing environ-mental conditions. This paper proposes a precise PV simulator based on the seven-parameter electriccircuit model. The proposed simulator can generate the output characteristics of a PV system preciselyat different operating conditions. It has also enough flexibility to simulate different configurations ofPV panels with series/parallel connections. The robustness of the proposed simulator is demonstratedunder the partial shaded conditions. Additionally, the performance of the developed simulator is verifiedby interfacing it with the actual power electronic converter and maximum power point tracking (MPPT)controller. The proposed PV simulator will facilitate the design aspects of PV systems and help in behaviorassessment of newly developed controllers prior to practical implementation.

由于系统因素之间关系非常复杂，特别是其表面现象及变化的随机性、模糊性和灰色性，使人们在观察、分析、预测和决策时得不到足够的信息，找不到主要矛盾，从而给复杂系统的系统分析带来困难。这就需要灰色关联分析。(Because the system is very complex relationship between factors, especially changes in the surface phenomena and random, fuzzy and gray so that people in the observation, analysis, forecasting and decision-making can not get enough information, can not find the main contradictions thus to the complex system of systems analysis difficult. This requires gray relational analysis.)

This function requires the input of a 2D matrix containing intensity values (double) corresponding to the x-ray scattering image (‘imagemat’). It returns I(q) vs. q in matrix ‘IvsQ’. It loads the experimental parameters saved in A.1. Start and end pixel counts can be adjusted as needed. It is important to resize matrices ‘allpixels’ and ‘sortedpix’ accordingly.
