研究目的
To evaluate the reliability of photovoltaic power generation systems and analyze the weak links of the system using a fuzzy hierarchical evaluation method based on sensitivity analysis.
研究成果
The proposed fuzzy hierarchical evaluation method based on sensitivity analysis is of great significance for analyzing the reliability of the photovoltaic system and the weak link of the system. The evaluation results of the example in this paper are sorted from good to bad into battery>transmission circuit>controller>solar panel>inverter. The reliability index of the entire system is 3.4156, indicating that the safety level of the entire photovoltaic power generation system is relatively general.
研究不足
The analysis process of the overall reliability evaluation model of the traditional photovoltaic power generation system is complicated, and the shortcomings of the system weak link cannot be analyzed.
1：Experimental Design and Method Selection:
The method judges the whole system failure factor by introducing the fault frequency, the degree of fault impact, and the second evaluation criterion of the fault detection difficulty. The Monte Carlo-based component sensitivity analysis method is used to calculate the degree of fault impact.
2：Sample Selection and Data Sources:
The system generally consists of a photovoltaic array composed of solar cell modules, a solar charge and discharge controller, a battery pack, an off-grid inverter, a DC load, and an AC load.
3：List of Experimental Equipment and Materials:
Not explicitly mentioned.
4：Experimental Procedures and Operational Workflow:
The method is used to analyze a photovoltaic power generation system. The effectiveness of the proposed method is verified by the overall reliability analysis and the evaluation of fault factors.
5：Data Analysis Methods:
The fuzzy comprehensive evaluation method is applied to transform qualitative evaluation into quantitative evaluation according to the membership degree theory of fuzzy mathematics.
