Distributed coordinated operation method of plug-in electric vehicles in micro grid considering fluctuation of wind power

With the development of wind power generation, the problem of power fluctuation is increasingly prominent. The real-time reasonable controlling of plug-in electric vehicles (PEVs) can provide valuable ancillary service for balancing the active power and regulating the frequency of power systems. This paper proposed a coordinated PEV operation model based on the willingness to participation (WTP) parameter of charging patterns and maxima total utility’ of PEVs, in order to economically aiocate PEVs’power for alleviating wind power fluctuations in a micro-grid. Furthermore, to solve this model, a consensus theory based center-free scheme is designed to control PEVs’ charging/discharging power in real-time. The proposed scheme could flexibly satisfy PEV various charging scenarios including random arrival and departure time as well as the initial and desired State of Charge (SOC). Findly, the simulation is carried out in a micro-grid with 5 wind farms and 2 000 PEVs, and the simulation results show that the proposed coordinated operation model and distributed control method of PEVs can flexibly meet the daily flexible charging requirements of large-scale PEVs, and also effectively improve the frequency of micro-grids.
