The control strategy research of wind power and storage based on the black start

This paper first introduces the control model of energy storage system, using double closed-loop voltage current control and sine pulse width modulation technology, to control the charging and discharging process of energy storage system. At the same time introduces the model of the doubly-fed type winding, winding rotor side and network side respectively using CRPWM and SPWM technology, so that the winding can to stabilize the value output. Finally using PSCAD simulation software of doubly-fed winding and energy storage combined modelling unit model, and the energy storage battery to start the winding, and simulate the process of winding to charge energy storage battery, analyse the wind storage unit system stability.
