China Southern Power Grid Energiespeicher Deep Peak Shaving
Compared with Scenario 2, the final peak shaving demands of seven areas in China are simultaneously reduced in Scenario 3. The largest reduction rate is 14% from East
Will China's thermal power units be able to shave deep peak?
It will continue to force China’s thermal power units, especially coal-fired thermal power units, to carry out the flexibility transformation and upgrading of deep peak shaving ability.
What is the winning capacity of thermal power unit deep peak-shaving?
The winning capacity of thermal power unit deep peak-shaving not only depends on its technical output limit but also is affected by the unit quotation. In this example, the thermal power unit second grade deep peak-shaving quotation is 550 yuan/MWh, while the abandonment cost of renewable energy is 500 yuan/MWh.
Why is deep peak shaving a trend in China?
With the gradual deepening of the reform on both sides of energy supply and demand in China, it is an inevitable trend for thermal power units to carry out the flexibility transformation of deep peak shaving. Under the requirements of energy saving and emission reduction of China, backward coal-fired thermal power units will be further reduced .
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.
How to improve peak-shaving capacity of Ningxia power system?
Utilizing the deep regulation capability of thermal power units and energy storage for peak-shaving and valley filling is an important means to enhance the peak-shaving capacity of the Ningxia power system. There are existing references on the economic optimization of operation using energy storage and thermal power units.
Can new energy consumption alleviate the deep peak-shaving pressure of thermal power units?
In order to explore whether new energy consumption can alleviate the deep peak-shaving pressure of thermal power units, this paper establishes the relationship between the unit's deep peak-shaving operation index and the new energy consumption based on the unit's deep peak-shaving capacity index and new energy consumption-related indicators.
