Breakthroughs have been made in the key technology of stand-alone 10MW energy storage bidirectional inverters

In recent years, with the vigorous development of the new energy industry, large-scale energy storage systems that can support the safe and stable operation of the power grid have attracted more and more attention
.
On May 28, at the 12th International Solar Photovoltaic and Smart Energy (Shanghai) Exhibition, a row of seemingly ordinary black cabinets attracted many visitors at home and abroad, they are the heart of the energy storage system - 10MW energy storage bidirectional inverter
.

According to reports, for the power grid, what is needed is a large-scale energy storage system above the 100 MW level, which means that about 200 sets of 500KW bidirectional inverters are needed to meet the construction requirements
of large-scale energy storage power stations.
However, with the advent of a single-unit 10MW-level energy storage bidirectional inverter, the 100MW-level energy storage system only needs to coordinate 10 inverters to complete the system construction
.

It is understood that at present, pumped storage power stations are widely used in China to cope with power dispatching requirements, although the stability of the power station is high, but the project cycle is as long as 5 to 6 years, the power loss rate is 30%, and it takes a few minutes to respond to dispatching instructions
.
With the breakthrough of the key technology of stand-alone 10MW energy storage bidirectional inverter, the future electrochemical energy storage power station above 100MW can be put into operation in only half a year construction cycle, and the power loss rate will be reduced to about 15%, which can respond to the peak regulation and frequency regulation requirements
of the main power grid in milliseconds.
A new generation of intelligent, controllable, flexible and green power systems will be realized
in China.
