How can I obtain accurate load data to use for load flow analysis?
Accurate modeling of load data is the most difficult part of creating a model of a distribution system. DESS provides extensive tools for modeling load variation over time (using Load Categories). For most large distribution systems (e.g. municipal and rural systems), the best data to use is the monthly kWh billing data, which can usually be exported from the billing system. It is accurate, and by combining this data with the profiling data in a Load Category, it is possible to create a model of the distribution system which accurately represents the variation of load from hour to hour, day to day, and season to season.
