Active power control system of energy storage power station

What is active power control?

The active power control performs a peak shaving logic that has been already tested and explained by the authors in Sbordone et al. (2015). The monitoring and control system read the active and the reactive power in the measurement point.

Does reactive power control affect a distribution feeder?

One way to mitigate such effects is using battery energy storage systems (BESSs), whose technology is experiencing rapid development. In this context, this work studies the influence that the reactive power control dispatched from BESS can have on a real distribution feeder considering its original configuration as well as a load transfer scenario.

What is adaptive multi-energy storage coordinated optimization?

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.

Can multi-energy storage support black-start based on dynamic power distribution?

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.

What is the control model of energy storage VSC?

The control model of energy storage VSC In order to ensure the smooth implementation of black-start, as the ESSs used in this paper is the auxiliary black-start power supply. One of the ESSs is controlled by V/f, which can keep the stable frequency and voltage.

How is energy storage power station distributed?

The energy storage power station is dynamically distributed according to the chargeable/dischargeable capacity, the critical over-charging ES 1# reversely discharges 0.1 MW, and the ES 2# multi-absorption power is 1.1 MW. The system has rich power of 0.7MW in 1.5–2.5 s.
