PROJECT TITLE :

An Aggregate Model of Plug-In Electric Vehicles for Primary Frequency Control

ABSTRACT:

The penetration level of plug-in electric vehicles (PEVs) has the potential to be notably increased in the close to future, and as a consequence, power systems face new challenges and opportunities. In particular, PEVs are in a position to supply different varieties of power system ancillary services. The capability of storing energy and therefore the instantaneous active power control of the quick-switching converters of PEVs are two attractive features that enable PEVs to provide numerous ancillary services, e.g., primary frequency control (PFC). But, concurrently, PEVs are obliged to be operated and controlled among limits, that curbs the grid support from PEVs. This paper proposes a new model for PEV employing a participation issue, that facilitates the incorporation of many PEV fleets characteristics like minimum desired state of charge (SOC) of the PEV owners, drive train power limitations, constant current and constant voltage charging modes of PEVs. So as to scale back computational complexity, an combination model of PEVs is provided using statistical data. In the top, the performance of PEVs for the provision of PFC is evaluated during a power system. Results show that PEV fleets will successfully improve frequency response, once all the operating constraints are respected.
