Peak regulation and energy storage at offshore wind power base

What is the difference between wind power and peak regulation?

Wind power is intermittent, random and has the character of anti-peak regulation, while the rapid growth of wind power and other renewable energy lead to the increasing pressure of peak regulation of power grid [1, 2, 3].

How energy storage system works in a wind farm?

The energy storage system acts as an auxiliary peak shaving source supply and coordinates with the thermal power unit to assist peak shaving. When the output of thermal power unit is less than the minimum output allowed by thermal power unit, the energy storage system is charged to absorb the output of wind farm.

Can an energy storage system be integrated with offshore wind farms?

The integration of an energy storage system (ESS) with the offshore wind farms is a convenient and feasible solution to overcome this drawback .

How to optimize a wind farm with energy storage?

Optimization for the whole wind farm with energy storage is developed. Wind turbines power tracking is realized through individual pitch control. Fatigue load is mitigated leading to a 10% service lifespan extension. A multi-scale optimize and control scheme is developed.

Can energy storage control wind power & energy storage?

As of recently, there is not much research done on how to configure energy storage capacity and control wind power and energy storage to help with frequency regulation. Energy storage, like wind turbines, has the potential to regulate system frequency via extra differential droop control.

Can energy storage systems reduce wind power ramp occurrences and frequency deviation?

Rapid response times enable ESS systems to quickly inject huge amounts of power into the network, serving as a kind of virtual inertia [74, 75]. The paper presents a control technique, supported by simulation findings, for energy storage systems to reduce wind power ramp occurrences and frequency deviation .
