Principle and composition of PV-ESS storage and charging system
Created on 09.05
This project is mainly composed of photovoltaic battery components, photovoltaic carports, grid-connected inverters, energy storage converters (PCS), energy storage batteries, charging pile equipment and billing systems, AC grid-connected cabinets and integrated monitoring systems. 380V low-voltage grid connection is adopted.
The components of the system are introduced as follows:
Solar battery components: Made of crystalline silicon, its function is to convert solar radiation energy into electrical energy, and it has certain rain, hail and wind protection capabilities. According to actual needs, the battery components can be connected in series and in parallel.
Grid-connected inverter: A power conversion device that converts the DC current from the solar cell array into AC current that meets the requirements of the national power grid.
Energy storage battery: used to store electricity. This project adopts a lithium iron phosphate battery solution with good safety.
Energy Storage Converter (PCS): It can control the charging and discharging process of the battery and perform AC and DC conversion. The PCS controller receives background control instructions through communication and controls the converter to charge or discharge the battery according to the sign and size of the power instruction. The PCS controller communicates with the BMS through the CAN interface to obtain the battery pack status information, which can realize the protective charging and discharging of the battery and ensure the safe operation of the battery.
AC distribution cabinet: The AC distribution cabinet mainly provides the inverter/energy storage converter with a grid-connected interface through power distribution. The distribution cabinet contains grid-side circuit breakers, lightning arresters, power generation meters, inverter/energy storage converter grid-connected interfaces, and AC voltage and current meters.
EV Charging system: The charging pile is equivalent to the power load in this system and can be matched according to the actual needs of the project.
Comprehensive monitoring system: The photovoltaic inverter and energy storage system are equipped with data acquisition modules, which can upload the power generation information and operating status to the cloud platform management system in real time. Through this monitoring system, all photovoltaic and energy storage equipment data can be centrally managed.
