Frequency control ancillary services, particularly for secondary (minute to minute) control, are also identified to be of key significance and should be set dynamically to minimize integration costs.
A promising solution to this problem is to use the batteries contained within electric vehicles (EVs) equipped with bi-directional charging systems to facilitate ancillary services such as frequency regulation and load balancing through vehicle to grid (V2G) technologies.
We consider the problem of designing distributed generation and demand control schemes that provide ancillary service in primary frequency regulation in power networks such that stability and fairness in the power allocation can be guaranteed.
ESS can also provide ancillary services for example frequency control.
In addition to this, EVs have been used to provide ancillary services, such as frequency control [43, 44].
