Composite optical storage and charging network integrated system

Abstract

The invention relates to a composite light storage and charging network integrated system. The integrated system is applied to a medium and low voltage power grid and charges and discharges an energy storage battery, a photovoltaic battery and an automobile battery. The integrated system comprises a primary alternating current bus and a plurality of box-type converters, the plurality of box-type converters are connected between a medium and low voltage power grid and the primary alternating current bus, and the integrated system further comprises at least one optical storage and charging grid energy routing module, each optical storage and charging network energy routing module comprises a bidirectional converter AC / DC, a secondary DC bus and a group of devices, and the devices comprise a bidirectional rectifier DC / DC, a first unidirectional rectifier DC / DC and a second unidirectional rectifier DC / DC. According to the invention, the energy routing module is integrated into the power scheduling system, and after the energy routing module integrates the energy of the optical storage and charging network, pooling is carried out through the power flexible scheduling system, so that the hybrid energy of the optical storage and charging network is dynamically distributed on the flexible scheduling system to charge the vehicle.
