It is well known that solar photovoltaic (PV) power generation is an important part of the strategy to realize sustainable development of energy and electricity. However, PV output power has strong volatility and randomness, and the instability of PV power seriously restricts the access and delivery of PV power.

 

And PV energy storage technology can realize peak shaving, load tracking, frequency and voltage regulation, power quality management and other functions.

 

PV energy storage system can also be in the PV power station encountered abandoned light limit power generation will be excess power into the storage battery. PV power generation is lower than the limit value or the evening peak power consumption through the storage inverter will battery power into the grid, energy storage system to participate in the grid peak shaving and valley filling.

 

The energy storage system can also utilize the peak and valley electricity price difference to create greater economic benefits, improve the system's own regulation ability, as a solution to large-scale renewable energy power generation access to the grid as an effective support technology.

 

1. The power supply DC side of the energy storage system. Mainly installed in DC systems such as photovoltaic power generation, this design can be combined with the battery photovoltaic power generation array in the DC section of the inverter for mating regulation.

 

2. The AC side of the power supply energy storage system, can also be called configured in the AC side of the energy storage system.

 

3. Load side energy storage system. Mainly refers to the emergency power supply and mobile electric equipment, such as rechargeable electric vehicles, power tools and cell phones.
