Demand Flexibility Time Intervals for Aggregate Residential Load Patterns

This paper deals with the definition of demand flexibility time intervals. These intervals are extracted from the binomial probability model of load variation patterns with the two possible categories of increase and non-increase in demand. These intervals along with the information on the coefficient of variation of the aggregate demand are used to assess the potential of demand flexibility exhibited by the aggregate residential demand in different periods of the day. The results of the proposed approach are useful for the distribution system operator or an aggregator to effectively set up demand response programmes in suitable time slots of the day.
