6 FAQs about [Analysis of the benefits of thermal power storage peak regulation]
What is the optimal energy storage allocation model in a thermal power plant?
On this basis, an optimal energy storage allocation model in a thermal power plant is proposed, which aims to maximize the total economic profits obtained from peak regulation and renewable energy utilization in the system simultaneously, while considering the operational constraints of energy storage and generation units.
Do I need to charge the energy storage system for peak shaving?
The dispatching department calls it for free. When the output of thermal power unit is between (1 − k) Pthe and 0.5 Pthe, the thermal power unit has the ability for peak shaving. At this time, there is no need to charge the energy storage system for peak shaving. To avoid deep discharge in energy storage system, SOCmin is set to 20%.
What is peak shaving of thermal power units?
Considering the operation status and energy consumption characteristics of thermal power units, peak shaving of thermal power units can be divided into conventional peak shaving, deep peak shaving of stable combustion without oil and deep peak shaving with oil .
How energy storage system works in a wind farm?
The energy storage system acts as an auxiliary peak shaving source supply and coordinates with the thermal power unit to assist peak shaving. When the output of thermal power unit is less than the minimum output allowed by thermal power unit, the energy storage system is charged to absorb the output of wind farm.
What happens if the output of thermal power unit is less?
When the output of thermal power unit is less than the minimum output allowed by thermal power unit, the energy storage system is charged to absorb the output of wind farm. If the output of thermal power is greater than 0.5 Pthe, the thermal power unit should share the responsibility of peak shaving. The dispatching department calls it for free.
