High temperature solar energy storage green peak-shaving power station

Which thermal power plant is best for peak shaving?

Through comparison, it can be found that under 30 % THA working condition, THS-7 has the strongest peak shaving ability, with a carbon reduction of 142.89 tons/h, which has a good environmental benefit for thermal power plants. THS-6 and THS-8 take second place, and other schemes cannot meet the requirement of peak shaving the load to below 20 %.

Can molten salt heat storage be integrated with deep peak shaving?

Due to the substantial capacity and high energy grade of thermal power units, their energy storage requirements encompass large capacity, high grade, and long cycle, the integration of molten salt heat storage with deep peak shaving for thermal power units is still at an early stage of technological development and demonstration application.

Does heat release increase peak shaving capacity?

However, thermal efficiency is higher with the multi-steam source strategy, and peak shaving capacity improves with an increased steam split ratio. During heat release mode, higher peak shaving capacity is achieved when steam is matched with the grade of cold reheat steam.

What is the energy storage scale of high-temperature molten salt storage?

For example, the energy storage scale of the high-temperature molten salt storage green peak-shaving power station in Jinchang City, Gansu Province reaches 600MW/3600MWh; The heat storage time is long and can achieve a heat storage capacity of more than 10 hours in a single day.

How do high-temperature thermal energy storage systems (HTTs) work?

Li et al. proposed three high-temperature thermal energy storage systems (HTTS) that store high-temperature steam heat during the heat storage stage and release it to the water supply during the heat release stage, thereby providing heat to the system.

What is the peak value of heat storage and heat release?

Comparative analysis of combined working conditions Under the combined working condition of heat storage and heat release, the peak value is adjusted downward to 603 MW during heat storage.
