Definition of optical storage and charging
The "photovoltaic storage and charging" integrated power station, in short, is a comprehensive function power station integrating photovoltaic power generation, energy storage and charging. It has three characteristics: 1. It can realize the self-use of photovoltaic power generation; 2. The surplus electricity is stored; 3. It can be combined with the energy storage peak and valley electricity price difference to arbitrage.
Operation mode
1. Grid-connected mode
The integrated light-storage-charge charging station is integrated into the power grid. In addition to receiving energy from photovoltaic solar panels, the energy storage battery is charged when the electricity price is low and discharged when the electricity price is high. Make up for the shortcomings of discontinuous solar power generation. When the power grid is out of power, the optical storage and charging system can use the off-grid operation mode to emergency charge the new energy vehicle.
2. Off-grid mode
In response to the island scene, when there is light, photovoltaic power generation supplies power to the charging pile and the energy storage, and when there is no light, the energy storage supplies power to the charging pile.
main value
1. Photovoltaic carport, spontaneous and self-use, and at the same time shelter the vehicle from wind and rain.
2. Energy storage can not only store photovoltaic energy, but also cut peaks and fill valleys, reducing electricity costs.
3. When the power grid is out of power, use emergency backup power as a backup power source.
4. Reduce the load pressure of the urban power grid without the need for capacity expansion.
