Technical Field

[0001] The present invention belongs to the field of data transmission, and particularly relates to a method, system, device and medium for equivalent regulation reserve between the load side and the power generation side. Background Art

[0002] Currently, most power markets still mainly rely on traditional power generation sides to participate in regulation. With the development of more load sides, there will be significant differences in the performance of unit regulation reserve. Therefore, in calculating the demand allocation of regulation reserve, existing methods cannot directly measure the performance differences between the power generation side and the load side in terms of regulation reserve.

[0003] With the advancement of power market reform, on the basis of traditional power generation sides participating in regulation, the load side can also participate. The addition of the load side poses some new challenges to the demand allocation of regulation reserve in the entire power market, and these challenges will become more significant in the future.

[0004] Currently, most power markets still mainly rely on traditional power generation sides to participate in regulation. With the development of more load sides, there will be significant differences in the performance of unit regulation reserve. Therefore, in calculating the demand allocation of regulation reserve, existing methods cannot directly measure the performance differences between the power generation side and the load side in terms of regulation reserve.

[0005] Currently, the description of the contribution of regulation reserve to differential targets in the power market is insufficient to evaluate their differences, and it cannot well measure the respective contributions of the power generation side and the load side during the process of joint participation in regulation, thus resulting in unreasonable price costs such as being too high or too low. Summary of the Invention

The SDEI is calculated through the second calculation module. f = 1, SDEI T = 41.44%, SDEI v = 87.23%. When both α and β are taken as 0.5, then SDEI = 64.33%.

[0124] Finally, the actual equivalent regulation reserve is calculated to be 0.1244 p.u. through the regulation reserve module.
