METHOD FOR CALCULATING DAILY LOAD CURVE OF ELECTRIC VEHICLE CONNECTED TO DISTRIBUTION SYSTEM BUS

摘要

The present invention relates to a method for calculating daily load curve of electric vehicle connected to distribution system bus to yield daily load for each bus considering the case for many electric vehicles to be connected to each bus of a distribution system for charging. The invention includes (a) a step to measure the number of framed structures connected to a bus out of many buses comprising distribution systems; (b) a step to measure the number of electric vehicles connected to one of the buses using the number of framed structures connected to one of the buses; (c) a step to yield a probability density function for charging start time of electric vehicles connected to one of the buses; and (d) a step to yield a charging daily load curve of an electric vehicle connected to one of the buses using the probability density function for the charging start time of an electric vehicle connected to one of the buses. The present invention has the effect to provide the base to design a plan to manage an electric vehicle charging load in the way to inhibit an extension of a distribution system maximally while meeting the over load restriction condition for each bus of distribution systems as accurately recognizing daily load by charging load of an electric vehicle connected to each bus of distribution systems.
