The proposed control approach is compared to the operating conditions of single thermal power unit regulation, thermal power energy storage combined regulation, and thermal power flexible load combined regulation using the model developed in this article. The system's primary source of power is a thermal power unit.
the integrated regulation strategy proposed in this paper determines the switching time and operating depth of the energy storage system and the flexible load, and makes rational and effective use of the frequency modulation resources to regulate, giving full play to their respective advantages.
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.
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.
In the power supply side, the energy storage system has the characteristics of accurate tracking [ 11 ], rapid response [ 12 ], bidirectional regulation [ 13 ], and good frequency response characteristics, is an effective means to maintain frequency stability [ 14 ].
The system performs less well in terms of stability the higher the average value of frequency change rate. The operation analysis indicators of energy storage system mainly include two aspects: one is the contribution of energy storage system to secondary frequency modulation Gbess, and the other is the operation status of SOC.
