Abstract

The invention discloses a method for determining the daily generating capacity of a distributed type photovoltaic power generation system. The method is carried out through the following steps: obtaining data information on the maximum value, the average value and the minimum value of the sunshine-related parameters at a user's location at all times through a meteorological data platform; obtaining data information on the generating capacity of the distributed type photovoltaic power generation system at all times through a local data monitoring center; obtaining data information on grid operation through a grid energy management system; assuming that the sunshine-related parameters and the user's battery charging events comply with the general multidimensional trapezoidal fuzzy distribution rules to determine the general multidimensional trapezoidal fuzzy set for the sunshine-related parameters and the battery energy storage charging active power control value; and based on the fuzzy probability analysis, determining the daily generating capacity of the distributed type photovoltaic power generation system. The invention can calculate the generating capacity of a photovoltaic power generation system in a day, and provides necessary technical support for distributed type new energy generation and smart grid dispatching operation.

Description

Technical field [0001] The present invention relates to the technical field of photovoltaic power generation, in particular to a method for determining the daily power generation of a distributed photovoltaic power generation system. Background technique [0002] The development of solar distributed power generation systems is the development trend of smart cities. Photovoltaic power generation and CSP are two different forms of solar power generation. In recent years, photovoltaic-photothermal integrated distributed power generation systems have become the mainstream direction of development and the subject of research hotspots. [0003] There will be great differences in solar radiation intensity and sunshine time in different areas, and there will be great differences, randomness and ambiguity at different times and spaces due to shadows formed by clouds in the same place. This uncertainty determines that the output of photovoltaic and solar thermal power generation systems als...
