Safty and Robustness


By adding the energy storage system in the power grid, it can realize peak load shifting, frequency and peak adjustment,

smooth the power generation and user side's energy as well as improve the quality of the power grid.

Specifically including:

1. Realize primary frequency modulation and secondary frequency modulation control, monitor load fluctuations in real time,

respond quickly to grid dispatching, improve grid frequency stability, and improve grid quality.

2. Improve the instability of the output power of wind power/photovoltaic power stations, especially the impact of transient

power on the power grid, thereby improving the power quality of new energy power stations and power grids.

3. Reduce the fluctuation instability of the user side power, smooth the power, improve the efficiency of user side energy, and

reduce the transformer capacity and the basic electricity cost of the user side.

4. According to the difference between the peak and lowest electricity prices, the PCS charges when the electricity price is low,

and discharges when the electricity price is high to obtain certain economic benefits.

>> Overview of Energy Storage System Application

Grid side, Generator side, User Side

The energy storage system includes an energy storage battery, a power conversion system (PCS), an energy management

system (EMS), and a battery management system (BMS).

Energy Storage System Block Diagram

The energy storage system can be combined with new energy power generation system (such as wind power and photovoltaic

power) and diesel generator system to form an off-grid or micro-grid system to solve the electricity demand of users in islands or

remote areas of power grids with unstable power supply. In the micro-grid system, the PCS needs to operate off-grid. For some

special load, the STS devices are required, which can realize automatic switching during the power failure and power restoration.

Off-grid/Micro-grid Application

In the above micro-grid system,

1. Select the capacity of the PCS according to the required power of the load. If the power of the load is large and multiple PCSs are

needed for expansion, the parallel control cabinet is required.

2. The isolation transformer can be placed independently on the outside or built in the PCS.

3. The off-grid PCS is used as a voltage source, and the constant AC output voltage is applied to the load PCS to absorbs energy from

the PV, and the excess is charged into the energy storage battery.

(1) When the power of the PV input port of the PCS is less than the AC output power, the energy storage battery begins to discharge;

(2) When the energy storage battery is discharged to a certain extent and may be difficult to support the load, the diesel is turned on,

and the PCS is switched from the off-grid operation to the simultaneous connection with the generator;

(3) When the power of the PV input is increased to above the load power, the diesel is turned off, and the PCS is automatically

switched to the off-grid operation.

>> Multi-machine Parallel Control Cabinet

When more than 3 PCSs are operating in parallel in the same system, it is necessary to add the multi-machine parallel control

cabinet for unified coordination. A grid-connected control cabinet is designed to support up to 20 PCSs in parallel.

If the PCSs need to realize automatic on-grid/off-grid seamless switch at the same time, the STS control cabinet must be added,

and the parallel control cabinet and the STS cabinet can be integrated.

Synchronization with PCS, free from external interference, high signal stability.

Each PCS is independent, and one or more of them are accidental shutdown or power failure

maintenance, which does not affect the normal operation of other PCSs.
