Embodiment Construction

[0035] Attached below figure 1 The present invention is described in detail:

[0036] Step 1: Mathematical formal description of site selection indicators

[0037] The site selection index system is a knowledge expression system, or a decision table. Among them, the specific geographical location is the object set of the decision table, and its corresponding various spatial characteristics are the condition attribute set of the decision table, and the level of the photovoltaic power station construction potential of the geographical location is the decision attribute set of the decision table. Accordingly, the site selection index system is expressed in a formalized way as follows:

[0038] Let tuple S=T ,V C , f> represents the location decision training set. Among them, D represents the geographic location; T is the set of spatial feature vectors of these locations; C is the classification method of the potential for building sites defined in advance by the system; V T ...

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...
