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 %.
In this strategy, part of the power commands are assigned to the energy storage system through fuzzy control, so as to establish the primary frequency modulation scheduling module of the thermal power unit coupling energy storage system, which can ensure the power generation revenue of thermal power units.
