6 FAQs about [Steam energy storage peak load regulation]
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.
What is a single steam source heating storage strategy?
In the single steam source heating storage strategy, a portion of the live steam enters the preheater and heat exchanger, facilitating sensible heat exchange with cold molten salt. This process converts the cold molten salt into hot molten salt, which exhibits improved liquidity following heat exchange.
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.
What is the maximum thermal load under minimum steam admission?
Under conditions of minimum steam admission, the maximum thermal load reduces to 102.92 MW, with the corresponding generation load at 153.53 MW.
What is a multi-steam source energy storage mode?
The multi-steam source energy storage mode is proposed based on the heat transfer characteristics of molten salt. Compared to the single steam source storage mode, the multi-steam source configuration demonstrates higher heat storage and thermal efficiency while maintaining the same peak shaving capacity during the storage phase.
