In recent years, the total capacity of wind power plants connected to power grid has increased drasticaly. However, intermittent output of wind power affect the frequency of the power system. In the night-time the capacity of Load Frequency Control (LFC) tends to be insufficient. On the other hand, Plug-in Hybrid Electric Vehicles (PHEV) are being developed as environment-friendly vehicles. PHEV is a kind of hybrid electric vehicles that can be charged from power grid. The batteries of PHEVs are charged mainly in night-time.In this paper, the authors proposed the charge control of batteries for PHEVs that compensate the capacity of LFC in the night-time and evaluated the allowable capacity of wind power generations in the penetration scenarios of PHEVs in three areas in Japan. The charge of the batteries was based on driving patterns of passenger vehicles and charging patterns in the night-time that the authors analyzed in this paper. Thereafter, charge control for PHEVs was simulated using transfer fanction models. The authors conducted the simulations and obtained the following results. (1) Charge control for PHEVs can suppress the frequency deviation caused by short period fluctuation of wind power. (2) Charge control for PHEVs including optimal scheduling of charging electric energy with centralized control would suppress the frequency deviation more efficiently than charge control without optimal scheduling.
