A charging load control method for electric vehicles that consumes photovoltaic power generation in situ

Abstract

The invention discloses an electric vehicle charging load regulation and control method for locally consuming photovoltaic power generation. The method comprises steps of photovoltaic power generation output and electric vehicle charging load statistics and prediction, energy storage system capacity optimization calculation, electric vehicle charging load regulation and control strategies and photovoltaic grid connected power statistics and analysis. The beneficial effects are that the local consumption level of photovoltaic power generation is improved, the phenomenon of discarding light caused by poor consumption is greatly reduced, the photovoltaic power generation grid connected operation cost is reduced at the same time, and the continuous development in the photovoltaic industry is greatly promoted.

Description

technical field [0001] The invention belongs to the field of new energy and energy saving, and in particular relates to a charging load control method of an electric vehicle for on-site consumption of photovoltaic power generation. Background technique [0002] In recent years, my country has successively issued a series of supporting policies for photovoltaic power generation. The scale of photovoltaic power generation has expanded rapidly and has become an important force in clean energy. Since 2013, my country's photovoltaic power generation has added installed capacity exceeding 10 million kilowatts for three consecutive years. , becoming the world's largest photovoltaic power generation market. As of the end of 2015, my country's cumulative installed capacity of photovoltaic power generation was about 43 million kilowatts, surpassing Germany to rank first in the world. [0003] According to the national "Energy Conservation and New Energy Automobile Industry Development...

Problems solved by technology

Under the background of the large-scale application of photovoltaic power generation and electric vehicle charging facilities, there are currently two main problems: (1) The consumption level of photovoltaic power generation is not high, and there is a serious phenomenon of "light abandonment" in some 00 areas, and local consumption The receiving capacity needs to be improved; (2) The electric energy supply of electric vehicles is still dominated by electric energy generated by non-renewable energy sources (such as coal and natural gas), and the clean substitution of electric energy for electric vehicles has not been fundamentally realized
