In this paper, we study the problem of phase balancing with energy storage in the presence of system uncertainty. . Asahigh-qualityregulationresourceinthenewpowersystem,pumped storage units play a significant role in enhancing the reactive power regulation capacity of the power grid and increasing the system's rotational inertia. The proposed algorithm does not require any system statistics and asymptotically achieves the minimum system cost. . Therefore, to reduce frequency deviations caused by comprehensive disturbances and improve system frequency stability, this paper proposes an integrated strategy for hybrid energy storage systems (HESSs) to participate in primary frequency regulation (PFR) of the regional power grid. In intelligent grid, energy. . ation of key performance indicators. Capacity,voltage,C-rate,DOD,SOC,SOH,energy density,power density,and cycle life collectively impact efficienc ility has become a research hots construction of future power system.
