Problems solved by technology

The safety of solar energy utilization will not only have a great impact on the economics of grid operation, but also limit the development of photovoltaic power generation to a certain extent.
At the same time, due to the intermittency of photovoltaic power generation and the differences in solar energy in different regions, it is difficult to compare the security of different photovoltaic power plants connected to the grid

Embodiment Construction

[0052] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the implementation examples described here are only used to illustrate and explain the present invention, and are not intended to limit this invention.

[0053] Analytical Hierarchy Process (AHP for short) was formally proposed by Thomas Sety, an American operations researcher, in the mid-1970s. It is a systematic and hierarchical analysis method that combines qualitative and quantitative analysis. This method divides the various factors in the complex problem into several interrelated levels and makes them organized. According to the fuzzy judgment of the objective reality, it gives a quantitative expression of the relative importance of each level, and then uses mathematical methods to determine all factors. ...

Abstract

The invention discloses a photovoltaic grid connected safety evaluation method, which comprises the following steps of step 1, selecting a photovoltaic power station grid connected safety evaluation index, and building an evaluation matrix according to the index; step 2, carrying out index syntropy processing and dimensionless processing on the evaluation matrix to obtain a standard evaluation matrix; step 3, confirming the evaluation matrix and an index weight vector based on an analytic hierarchy process; step 4, utilizing a method of distance of good-bad solutions to calculate relative proximity corresponding to each photovoltaic power station, and realizing comprehensive evaluation on photovoltaic power station grid connected safety through sorting of the relative proximities. The photovoltaic grid connected safety evaluation method can comprehensively and objectively evaluate the safety running conditions of the photovoltaic power station grid connection, and provides the evaluation basis for the photovoltaic power generation grid connected safety conditions for an electric power department.
