How can peak load regulation flexibility be transformed?

The demonstration project for the transformation of peak load regulation flexibility through extracting steam and molten salt heat storage at the Hebei Longshan Power Plant of CHN Energy Investment Group (CHN Energy) started construction recently.

Why do power generation units need peak load regulation?

This allows the units to meet the needs of grid load regulation and make room for new energy power generation. When the power grid is at peak load, the heat stored in the heat storage system during the load regulation can be released to increase the peak load capacity of the power generation units.

How long will the peak load regulation capacity increase?

Upon completion, the plant's unit peak load regulation capacity will increase by 100 MW, for up to four hours; the peak load capacity will be increased by 47 MW, and the heat release time will be no less than six hours.

How can energy storage systems meet the demands of large-scale energy storage?

To meet the demands for large-scale, long-duration, high-efficiency, and rapid-response energy storage systems, this study integrates physical and chemical energy storage technologies to develop a coupled energy storage system incorporating PEMEC, SOFC and CB.

What is China's first large-scale chemical energy storage demonstration project?

The project is the first national large-scale chemical energy storage demonstration project approved by the National Energy Administration of China, with a total construction scale of 200MW/800MWh. The grid connection is the first phase project of the power station, with a scale of 100MW/400MWh.

What is the power and capacity of Es peaking demand?

Taking the 49.5% RE penetration system as an example, the power and capacity of the ES peaking demand at a 90% confidence level are 1358 MW and 4122 MWh, respectively, while the power and capacity of the ES frequency regulation demand are 478 MW and 47 MWh, respectively.
