Abstract

The invention relates to an entropy weight method resistance based photovoltaic power station operation characteristic assessment method, and belongs to the technical field of photovoltaic power generation. The entropy weight method resistance based photovoltaic power station operation characteristic assessment method includes firstly, establishing an assessment indicator system taking electric quantity, energy consumption, efficiency, power generation hours and power station operation hours as indicators, and acquiring the related indictors through collection and calculation; preprocessing the related indicators acquired by calculation to acquire an average indicator matrix; calculating anti-entropies of the indicators according to the average indicator matrix; finally, calculating weights of the indicators according to the anti-entropies and calculating an assessed value of photovoltaic power station operation characteristics according to the weights to realize assessment of the photovoltaic power station operation characteristics. The entropy weight method resistance based photovoltaic power station operation characteristic assessment method has the advantages that a photovoltaic power station performance assessment mathematic model is created through establishment of the assessment indicator system for the photovoltaic power station operation characteristics, so that scientific guidance and shared power station experiences are provided for overall operation performance assessment of photovoltaic power stations, and development of operation and maintenance of the photovoltaic power stations is promoted.

Description

technical field [0001] The invention relates to a method for evaluating the operating characteristics of a photovoltaic power station based on an anti-entropy weight method, and belongs to the technical field of photovoltaic power generation. Background technique [0002] As a kind of clean energy, photovoltaic power generation has received extensive attention worldwide. There are more and more large-scale ground photovoltaic power stations and distributed rooftop photovoltaic power stations in my country. According to statistics, the total installed capacity of photovoltaic power generation in my country at the end of 2014 reached 35GW. However, the construction quality, power generation efficiency and average availability of photovoltaic power plants have become the most concerned topics for photovoltaic business investors. [0003] The operating characteristics of existing photovoltaic power plants have not yet proposed relatively complete evaluation indicators and evalua...
