In the end, a control framework for large-scale battery energy storage systems jointly with thermal power units to participate in system frequency regulation is constructed, and the proposed frequency regulation strategy is studied and analyzed in the EPRI-36 node model.
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.
At present, there have been many research results on hybrid energy storage participating in the primary frequency regulation control strategy of the power grid both domestically and internationally. Yang Ruohuan built a new superconducting magnetic energy storage and battery energy storage topology.
With the gradual increase of energy storage equipment in the power grid, the situation of system frequency drop will become more and more serious. In this case, energy storage equipment integrated into the grid also needs to play the role of assisting conventional thermal power units to participate in the system frequency regulation.
In terms of power grid assessment, hybrid energy storage can effectively improve the frequency modulation capability of the unit, improve the frequency modulation performance, and reduce the frequency modulation assessment of the power grid.
