A Multi-type Energy Storage Control Strategy for Promoting Renewable Energy Consumption and Active-Support Ability

The development of a new type of power system based on renewable energy will seriously degrade the system frequency characteristics and the level of safety and stability, which needs to be solved urgently. In order to promoting new energy consumption and active-support ability, this paper proposes a multi-type energy storage system(MTESS) control strategy based on frequency domain decomposition algorithm on the side of renewable energy power station (REPS), which can realize the multi-type energy storage system to efficiently meet the requirements of reducing the curtailment rate and compensating for the power prediction error, energy storage demand in the complex process of primary frequency modulation demand in random high frequency. Finally, the feasibility and superiority of this control method are proved by the analysis of practical examples.
