Distributed photovoltaic energy storage charging system

Abstract

The invention discloses a distributed photovoltaic energy storage charging system which is applied to a building group in a set range. The system comprises a plurality of fixed photovoltaic devices and photovoltaic devices with fixed installation angles, which are are respectively arranged at positions where solar rays are always not shielded by buildings in the range of the building group; a plurality of movable photovoltaic devices which are arranged to be photovoltaic devices with rotating angles and are respectively arranged at the positions where solar rays are blocked by buildings in therange of the building group; a charging and discharging controller which is in bidirectional connection with the fixed photovoltaic device and the movable photovoltaic device so as to output the electric energy generated by the fixed photovoltaic device and the movable photovoltaic device to an electric load connected with the charging and discharging controller. The occupied land problem can bereduced, the productivity efficiency of the photovoltaic devices is improved, and energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a distributed photovoltaic energy storage and charging system. Background technique [0002] At present, the existing electricity for houses, scenic spots, and commercial uses are generally drawn from the city power. If the city power fails, it will cause power outages in houses, scenic spots, and shops at the same time, which will affect the lives of residents. At the same time, a large number of electrical equipment starts at the same time during the peak period of electricity consumption, which will bring an excessive burden and impact on the mains, and will directly lead to the paralysis of the mains. [0003] In order to reduce the burden on the city power and integrate the concept of energy saving and emission reduction, an independent power supply system will be used in a certain range of residential areas, shops or scenic spots to supply power to the...
