This paper proposes a coordinated frequency regulation strategy for grid-forming (GFM) type-4 wind turbine (WT) and energy storage system (ESS) controlled by DC voltage synchronous control (DVSC), where the ESS consists of a battery array, enabling the power balance of WT and ESS hybrid system in both grid-connected (GC) and stand-alone (SA) modes.
Frequency control of power grids has become a relevant research topic due to the increasing penetration of renewable energy sources, changing system structure, and the integration of new storage systems, controllable loads and power electronics technologies.
The frequency regulation power optimization framework for multiple resources is proposed. The cost, revenue, and performance indicators of hybrid energy storage during the regulation process are analyzed. The comprehensive efficiency evaluation system of energy storage by evaluating and weighing methods is established.
Due to the fast response of power electronic interfaces, this regulating power can be injected into the grid in a short time [11, 12]. Demand response (DR), i.e. controlling loads and flexible demand-side units, also provides a promising scheme for power grids frequency regulation .
Furthermore, numerous research works have been recently focused on the use of DGs, RESs, MGs, electric vehicles, and storage devices to provide frequency control support in power grids , , , , , , , , .
