Method for establishing location selecting model of mountain photovoltaic power station

Abstract

The invention relates to the technical field of a space strategy supporting system in a geographic information system, in particular to a method for establishing a location selecting model of a mountain photovoltaic power station. The method comprises the following steps of conducting digital formalized description on a location factor and a corresponding index of the mountain photovoltaic power station according to the characteristics of the mountain photovoltaic power station; regarding a multidimensional location selecting index knowledge base, deriving a smallest location selecting property subset through a fuzzy rough set to replace an original property set on the basis that the location selecting classification capacity is not reduced, and obtaining a location selecting strategy list; extracting the corresponding property characteristic in the location selecting strategy list from a GIS, and establishing a membership degree function to evaluate and classify the station establishing potential of a specific geographical position. The method for establishing the location selecting model of the mountain photovoltaic power station can conduct quantitative relation derivation according to the situation that a plurality of micro and macro factors influence power generation amount of the power station to obtain a main influence factor. The space property relationship is analyzed based on a GIS data base, and direct strategy support to the location selecting of the mountain photovoltaic power station is provided.

Description

Technical field: [0001] The invention relates to a method for establishing a site selection model of a mountainous photovoltaic power station, which belongs to the technical field of spatial decision support systems in geographic information systems. Background technique: [0002] Before the construction and planning of photovoltaic power plants, site selection must be carried out first. Reasonable location selection is very important to the output of light energy [1] , Unreasonable site selection will directly result in the loss of power generation of the power station and increase in maintenance costs, the overall benefit and operating life will be reduced, and it may also cause adverse effects on the surrounding environment. Existing site selection methods and models for photovoltaic power plants have their own applicable conditions, and appropriate methods and models should be selected according to different places and environments. For the site selection of mountain p...

Problems solved by technology

[0003] Although the geographic information system (GIS) has been popularized at present, the current GIS software data models are non-temporal, and it is difficult to describe the spatio-temporal distribution mode of spatial information well, and the attribute information in the spatial information is only used for retrieval and query. , or simple statistics, it is difficult to conduct in-depth analysis to discover the underlying patterns and laws [2] , cannot provide direct decision-making support for the site selection of mountain photovoltaic power stations
