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 %.

Why should thermal power units carry out deep peak shaving?

However, when thermal power units carry out deep peak shaving, their economy will be considerably reduced , and the thermal power units face many problems under low load conditions . Only by changing this situation can we achieve deep integration of thermal power generation and renewable energy development.

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.

How to achieve a 'zero output' peak shaving?

If combined with the technology of "extraction steam energy storage energy storage + electric heating + molten salt energy storage", the "thermoelectric decoupling" and the "zero output" peak shaving of the unit can be achieved throughout the year.

What is peak shaving?

In many countries, electricity prices for large-scale consumers are set with reference to their maximum peak load. Many enterprises with high energy consumption began to reduce the power grid consumption by installing photovoltaic systems and battery energy storage, that is peak shaving.

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.
