Abstract

An intelligent power grid comprehensively utilizing a social energy storage system comprises a load; an uninterruptible power supply which is used for temporarily supplying power to the load when thepower grid is powered off; a standby generator which is used for temporarily supplying power to the load when the power grid is powered off; a charging pile which is used for being connected with theelectric vehicle and supplying power to the electric vehicle or taking power from the electric vehicle; and a local area network intelligent center which is used for controlling the charging pile acquire power from the electric vehicle based on time-of-use electricity price, an electric vehicle reservation plan, electric vehicle remaining capacity, electricity consumption required by a load and power supply and outage conditions of a power grid when the power grid is powered off accidentally and the electric vehicle can discharge outwards, and when the power grid supplies power normally, the electric vehicle is controlled to charge and discharge according to the lowest electricity cost principle. According to the intelligent power grid, the intelligent center is utilized, the social standby power supply is combined, and the electric vehicles with huge ownership are added, so that available electric power can be automatically distributed when the power grid fails, the failure resistanceof the whole power grid is improved, and the operation cost of the power grid can be reduced during normal operation.

Description
