-Functions of Storage Power Station
Peak-Shaving Function
In one sense, store electric energy when it is surplus and output stored electric energy after inverting when it is insufficient. This is the basic function of storage system--Peak-shaving function.
Independent inverting function in emergency
When the power grid loses electric energy, storage system will be used as independent inverter power supply and provide AC electric power for important load constantly to ensure user's requirement.
Accepting Debug Command From Power Grid Flexibly
Storage system will exchange information with Remote Terminal Units (RTU) of power grid and Supervisory Control And Data Acquisition (SCADA) flexibly and conveniently, it will accept dispatch from automatic dispatch monitoring system of electric grid, to realize telesignalling, telemeter, remote control and remote transfer. The whole process will abide by MODBUS RTU. The communication media maybe wireless or wired.
Dynamic, static power grid support and reactive power compensation
Storage system will achieve kinds of functions according to power grid dispatch command, which includes items as follows:
- Provide needed active power for power grid;
- Provide needed reactive power for power grid;
- Realize low voltage cross, and enhance the stability of power grid.
