Kind of family power optimization method based on electric vehicle energy storage characteristics

The present invention discloses a storage feature based on forecast price and electric vehicles, according to the discharge revenue loss costs the cost of electricity appliances, charging the cost of batteries for electric vehicles, batteries for electric vehicles as well as batteries for electric vehicles to determine the electricity cost optimization the battery charge state SoC, when its electric car battery SoC returning state that is higher than the cost of electricity to meet the optimization of the battery state of charge SoC, for non-adjustable load power supply, thereby reducing household electricity costs while reducing the power grid at its peak load. Meanwhile, on this basis, can effectively avoid the high-power charging load to a new peak load electricity grid brought and adjust according to the load forecast electricity price will be adjusted to lower peak and trough the use of electricity to maximize the fill low load, effectively resolves the contradiction substantial increase in demand for electricity and household electricity costs between users.
