How to improve the frequency regulation capacity of thermal power units?
In order to enhance the frequency regulation capacity of thermal power units and reduce the associated costs, multi-constrained optimal control of energy storage combined thermal power participating in frequency regulation based on life loss model of energy storage has been proposed. The conclusions are as follows:
Can energy storage support the frequency regulation of thermal power units?
Comprehensive evaluation index performance table. Therefore, in the current rapidly developing new energy landscape where conventional frequency regulation resources are insufficient, the proposed strategy allows for more economical and efficient utilization of energy storage to support the frequency regulation of thermal power units.
Should thermal power units meet the SOC state limit?
In the past power grid dispatching, for the frequency regulation constraint of the combined system of thermal and energy storage, the thermal power units should meet its climbing ability and the energy storage should meet the SOC state limit, as described below.
Why is energy storage output used in esctpfr?
The energy storage output is utilized to compensate for the insufficient frequency regulation capacity of thermal power, thereby reducing their wear. The power of energy storage is constrained by the SOC to minimize the number of energy storage cycles and improve its overall life. 3. Loss model of ESCTPFR
What is the difference between auxiliary regulation and energy storage system?
The output fluctuation of the thermal power unit is the biggest when the auxiliary regulation is only from the load side, and is relatively small when the frequency change rate is fast. The output of the energy storage system is small while the SOC consumption is small, and the frequency stability is not affected.
How does frequency regulation affect energy storage?
When the energy storage system must be charged under the condition of frequency regulation, the charge power absorbed by the energy storage system steadily decreases when the SOC is at a high boundary value, and it eventually cannot absorb the charge power when the SOC hits the critical value.
