Energy storage thermal power peak regulation

How does peak regulation affect the operating state of thermal power units?

While at the phase of normal peak regulation, the operation cost increases as the power output increases. Therefore, for economic operation, the optimal operating state of thermal power units better be maintained near the lower limit of normal peak regulation. Fig. 3. Deep peak regulation cost of thermal units.

Is there a trade-off between energy storage and peak regulation?

In the meantime, the trade-off between deploying energy storage and leveraging the deep peak regulation capacity of existing thermal generators remains to be explored.

How to optimize energy storage capacity suitable for thermal power units?

To optimize the energy storage capacity suitable for thermal power units and the charging and discharging strategies of energy storage, a robust optimization configuration and economic operation method for energy storage thermal power unit peak regulation system (ESTPPR) is provided.

Can thermal power units meet the increasing demands of regulation?

However, restricted by the motion inertia and friction loss of mechanical equipment, the adjustment speed of thermal power units cannot meet the increasing demands of regulation . Energy storage technology has gained significant attention over the years as a new resource for adjusting and solving the shortage of flexible resources [11, 12].

Why do thermal power plants need energy storage systems?

Thermal power plants are considering configuring energy storage systems to cope with different daily wind power uncertainty, ensure stable operation and power supply reliability of the power system, and alleviate problems such as deep peak regulation and frequent start and stop of thermal power units.

What is the difference between deep peak regulation and normal peak regulation?

It can be seen that at the phase of deep peak regulation, as the output of units decreases, the cost of thermal power unit continues to increase, which is due to the increased cost of oil input and equipment wear cost. While at the phase of normal peak regulation, the operation cost increases as the power output increases.
