Method for evaluating power generation insurance pricing for photovoltaic power stations

Abstract

The invention discloses a method for evaluating power generation insurance pricing for photovoltaic power stations. The method includes acquiring relevant indexes of monthly gross power generation, installed capacity, regions and the like of the photovoltaic power stations in a certain period and classifying the relevant indexes; acquiring monthly full-generation hours according to the gross powergeneration and the installed capacity, accumulating the monthly full-generation hours and calculating the sums of the monthly full-generation hours; normalizing and indexing the sums; computing fluctuation ratios and relevant fluctuation parameters of monthly power generation of each category of power stations to obtain the fluctuation ratios and the relevant fluctuation parameters of the monthlypower generation of a certain category of power stations and gross full-generation hour distribution of a certain period; determining pricing for the power stations according to the distribution. Themethod has the advantages that distribution of power generation of target power stations in future medium and long terms can be quickly and accurately estimated by the aid of the method, risks and values of the power stations can be accurately measured, and accordingly reference bases can be provided for insurance pricing and earning prediction for the photovoltaic power stations.

Description

technical field [0001] The invention relates to a photovoltaic power station power generation insurance pricing evaluation technology, in particular to a photovoltaic power generation power generation insurance pricing evaluation method. Background technique [0002] With the development of science and technology, electric energy is one of the main energy sources to maintain our life, work and social progress. The use of wind energy and solar energy to generate electricity has become one of the main sources of electric energy. Among them, photovoltaic power generation is based on the principle of photovoltaic effect, using solar cells to directly convert sunlight energy into electrical energy, and its main principle is the photoelectric effect of semiconductors. Photovoltaic power generation can be divided into independent photovoltaic power generation, distributed photovoltaic power generation and grid-connected photovoltaic power generation. With the large-scale developmen...

Problems solved by technology

Then, in the process of signing a new energy medium and long-term transaction contract, it is necessary to know how much electricity the new energy base (which can be a regional photovoltaic power plant group) needs to deliver in the next year or a few months, that is, in the next year or a few months The total value of new energy power generation in several months, and when executing long-term new energy transactions, it is necessary to decompose the required new energy power generation into the monthly power generation plan in order to better complete the planned total amount, then The problem involved in this process is how to obtain the total value of the power generation of photovoltaic power plants in the medium and long-term contract period in advance. However, the current long-term forecast method of photovoltaic power plants in the existing technology cannot give the distribution of power generation of power plants, which is used to It is impossible to accurately estimate the benefits and risks of insurance when pricing insurance, and the operation methods of existing technologies are complicated, have poor accuracy, and high data acquisition costs, which are not conducive to popularization and application
