By configuring energy storage combined thermal power units to participate in the AGC frequency modulation, not only the frequency modulation performance of thermal power units can be effectively improved, but also the adjustment depth of thermal power units can be increased, so as to obtain more compensation benefits.
Based on the above analysis, a control strategy based on cooperative frequency modulation of thermal power units and an energy storage output control system is proposed to improve the frequency stability of the power grid.
According to the above analysis, the energy storage technology can effectively improve the frequency regulation performance by assisting thermal power units to participate in power grid frequency regulation, and the control strategy proposed in this paper can prolong the service life of the energy storage system.
The dynamic frequency modulation model of the whole regional power grid is composed of thermal power units, energy storage systems, nonlinear frequency difference signal decomposition, fire-storage cooperative fuzzy control power distribution, energy storage system output control and other components. Fig. 1.
According to the above information, when the coupled hybrid energy storage of the thermal power unit participates in primary frequency modulation, the output power is significantly reduced, and the safety and stability of the unit are improved to a certain extent.
Under the four control strategies of A, B, C and D, the hybrid energy storage participating in the primary frequency modulation of the unit |Δ fm | is 0.00194 p.u.Hz, excluding the energy storage system when the frequency modulation |Δ fm | is 0.00316 p.u.Hz, compared to a decrease of 37.61 %.
