Aiming at the over-charge/discharge, an adaptive multi-energy storage coordinated optimization method is proposed. The power allocation is based on the chargeable/dischargeable capacity and limit power. A black-start model of multiple wind power and energy storage system model is established.
Coordinated control strategy of multiple energy storage power stations supporting black-start based on dynamic allocation in this paper can realize power balance and stable voltage frequency in black-start of the power grid.
According to the above literature, most of the existing control strategy of energy storage power stations adopt to improve the droop control strategy, which has a great influence on the system stability and cannot be controlled again in case of blackout.
In addition, the main energy storage functionalities such as energy time-shift, quick energy injection and quick energy extraction are expected to make a large contribution to security of power supplies, power quality and minimization of direct costs and environmental costs ( Zakeri and Syri 2015 ).
Aiming at the problem that wind power and energy storage systems with decentralized and independent control cannot guarantee the stable operation of the black-start and making the best of power relaxation of ESSs, a coordinated control strategy of multi-energy storage supporting black-start based on dynamic power distribution is proposed.
