With the increase of energy storage, the technology of optical storage system becomes more complex, and the time and power of battery charging and discharging are very critical. It is necessary to ensure the safe and stable operation of photovoltaic, energy storage and power grid, and fully consider the economy, so it is necessary to break through the barriers between hardware, software and system level.

There are many devices in optical storage integration system, which need to solve the interface compatibility problem of hardware and software between different devices. If the devices come from different manufacturers, the difficulty and cost of power station design, equipment procurement, operation and maintenance will increase. The most important thing is that the communication interface schemes between different devices are different, and integrators need to deal with different protocols and interfaces, It's difficult, so try to use the same company's products in the design.

The key of energy storage system integration is the safety management of DC side, that is, the safety management of battery system, which needs a very perfect system protection design. The four levels of cell, module, battery cluster and battery system management are closely linked. A good system protection design can know their operation status in real time, especially the temperature and voltage of the battery, which can be monitored and controlled from time to time. If there is a fault, it can realize step-by-step protection and rapid linkage protection.

Compared with the traditional economic dispatching mode of power station, the effective management of battery and converter in the energy storage power station should be fully considered when dispatching the photovoltaic power generation system, so as to improve the safety and economy of the whole operation of the photovoltaic power station.
