quency regulation services. However, modern power systems with high penetration levels of generation. Therefore, de-loading of renewable energy generations to provide frequency reg- ulation is not technically and economically viable. As such, energy storage systems, which support are the most suitable candidate to address these problems.
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.
During the extra power supply, the energy storage system actions as a load and gets itself charged whereas during the power shortage the energy storage system supplies power to keep the balance in demand and supply, and hence it lessens the frequency fluctuation.
Energy storage systems give power to the different loads when there is a shortage of power supply from the grid so that the stability of the power system is maintained due to its fast response. If the frequency severely deviates from the standard frequency, then many of the instruments connected to the power system can be damaged.
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.
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.
