Instructions of technological principle & features and commonly used power station storage methods

The power storage device composed of power storage elements and the grid access device composed of power electronic devices become the two major parts of the power storage system. The power storage device mainly realizes the storage, release or fast power exchange of power. The power grid access device realizes the bidirectional transfer and conversion of power between the power storage device and the power grid, It also realizes functions such as power peak regulation, energy optimization, improving power supply reliability and power system stability.
