Role of customized Expanded On-grid Photovoltaic Energy Storage System products

(Summary description)Through the analysis of the characteristics of photovoltaic power generation, it can be seen that the impact of the customized Expanded On-grid Photovoltaic Energy Storage System products on the power grid is mainly caused by the instability of photovoltaic power supply. From the perspective of safe, stable and economic operation of the power grid, the grid connected photovoltaic power generation system without energy storage will have an impact on line power flow, system protection, economic operation of the power grid Adverse effects on power quality and operation scheduling. The impact of the customized Expanded On-grid Photovoltaic Energy Storage System products, especially the grid connection of large-scale photovoltaic power stations, on the power grid can not be ignored. At present, the way to solve the impact of photovoltaic power stations on the power grid is to improve the flexibility of the power grid or configure energy storage devices for grid connected photovoltaic power stations.

Through the analysis of the characteristics of photovoltaic power generation, it can be seen that the impact of the customized Expanded On-grid Photovoltaic Energy Storage System products on the power grid is mainly caused by the instability of photovoltaic power supply. From the perspective of safe, stable and economic operation of the power grid, the grid connected photovoltaic power generation system without energy storage will have an impact on line power flow, system protection, economic operation of the power grid Adverse effects on power quality and operation scheduling. The impact of the customized Expanded On-grid Photovoltaic Energy Storage System products, especially the grid connection of large-scale photovoltaic power stations, on the power grid can not be ignored. At present, the way to solve the impact of photovoltaic power stations on the power grid is to improve the flexibility of the power grid or configure energy storage devices for grid connected photovoltaic power stations.

The role of the customized Expanded On-grid Photovoltaic Energy Storage System products is mainly reflected in the following aspects.
(1) The customized Expanded On-grid Photovoltaic Energy Storage System products ensures the stability of the system. In the customized Expanded On-grid Photovoltaic Energy Storage System products, there are great differences between the photovoltaic output power curve and the load curve, and there are unpredictable fluctuation characteristics. Through the energy storage and buffer of the energy storage system, the system can still operate at a stable output level even in the case of rapid load fluctuation.
(2) The energy reserve of the customized Expanded On-grid Photovoltaic Energy Storage System products. The customized Expanded On-grid Photovoltaic Energy Storage System products can play the role of standby and transition when photovoltaic power generation cannot operate normally. For example, when the battery array cannot generate power at night or in cloudy and rainy days, the energy storage system plays the role of standby and transition, and the amount of energy storage capacity depends on the demand of load.
(3) The customized Expanded On-grid Photovoltaic Energy Storage System products improves power quality and reliability. The expanded grid connected photovoltaic energy storage system can also prevent the grid fluctuation caused by voltage spike, voltage drop and other external interference on the load from having a great impact on the system. The use of enough energy storage systems can ensure the quality and reliability of power output.

Typical energy storage mode of customized Expanded On-grid Photovoltaic Energy Storage System products
According to different energy storage principles, it can be divided into electrochemical energy storage (such as sodium sulfur battery, liquid flow battery, lead-acid battery, nickel cadmium battery, supercapacitor, etc.), mechanical energy storage (such as pumped energy storage, compressed air energy storage, flywheel energy storage, etc.) and electromagnetic energy storage (such as superconducting energy storage).
