Distributed photovoltaic power generating capacity estimating system and solar radiation data generation method

Abstract

The invention discloses a distributed photovoltaic power generating capacity estimating system and a solar radiation data generation method, and is widely applicable to scientific research and engineering application in the area related to solar energy. A comprehensive calculating module utilizes a representative weather year and month method to acquire weather index data to calculate and analyze, an evaluated and quantized value acquiring module is used for overlapping and transforming total solar radiation data every day of the year generated in the comprehensive calculating module so as to acquire evaluated and quantized value, and a distributed photovoltaic power generating evaluating module compares the quantized value with a evaluation system to acquire a distributed photovoltaic power generating capacity evaluating result. The distributed photovoltaic power generating capacity estimating system and the solar radiation data generation method can be widely applied to various areas and weather conditions, the generated total solar radiation data every day of the year are representative, the evaluating result is objective and reasonable, and the requirement of distributed photovoltaic power generating planning engineering application can be met.

Description

technical field [0001] The invention belongs to a system in the field of distributed photovoltaic power generation planning, in particular to a distributed photovoltaic power generation capability evaluation system and a method for generating solar radiation data. Background technique [0002] Energy is the material basis for the existence and development of human society. According to the 2009 National Economic and Social Development Statistical Bulletin of the National Bureau of Statistics of China, the total energy consumption in 2012 was 3.62 billion tons of standard coal, an increase of 3.9% over the previous year. As the world's second largest energy consumer, China is facing the dual pressure of rapidly growing energy demand and increasingly serious environmental problems. Solar energy is a clean and renewable energy, which has been highly valued by our government. The annual solar radiation of more than 2 / 3 of my country's land area exceeds 6 billion joules per squ...

Problems solved by technology

At present, domestic research in this area is still relatively small, and only a few regions have fitted some simple empirical formulas for solar radiation, and the scope of application of these formulas is limited by regions and climates.
