Energy storage peak regulation direction of thermal power units

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.

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%.

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 is the load mode of peak regulation?

In the load mode of peak regulation, EH needs to meet operational constraints. The energy storage of TES should be within a reasonable range.

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.
