METHOD FOR CALCULATING DAILY LOAD CURVE OF DISTRIBUTION SYSTEM BUS BASED ON ELECTRIC VEHICLE CHARGING

摘要

The present invention relates to a method for calculating the daily load curve of a distribution system bus based on electric vehicle charging. More specifically, the present invention is a method for calculating the daily load curve of a distribution system bus based on electric vehicle charging to calculate daily load for each bus in the case in which many electric vehicles are connected to each bus of a distribution system for charging. The present invention includes (a) a step to calculate the number of frame structures connected to one of the buses comprising a distribution system; (b) a step to calculate the number of electric vehicles connected to a bus using the number of framed structures connected to a bus; (c) a step to yield the probability density function for the charging start time of an electric vehicle connected to a bus; (d) a step to yield a charging daily load curve of an electric vehicle connected to a bus using a probability density function of charging start time of an electric vehicle connected to a bus; and (e) a step to yield the daily load curve for the bus by adding the daily load curve for the rest of load calculated in advance except an electric vehicle connected to a bus to the charging daily load curve of an electric vehicle connected to a bus.
