This paper presents a method to estimate the loads on a distribution feeder in real-time with limited real-time customer load data from AMI. The method consists of two modules: a load clustering module and a load modeling module. Load clustering helps to identify customer loads with similar profiles thereby helping to determine the subset of customers that need to be monitored in real-time. The load...
Solid State Transformer (SST) average models are needed to enable system and protection studies. This paper focuses on fine tuning existing average models to replicate their switching counterparts and also discusses and validates control modifications required for successful grid integration. A 3 phase test system comprised of Substation SSTs and load SSTs of different ratings has been developed in...
This paper investigates the metrics for assessing the performance of alternative protection schemes for a distribution feeder. In addition to the main criterion which is the system reliability, the paper considers the other important factors as well which include stress on the substation transformer and the impact of momentary interruptions on customer load. Traditional reliability assessment indices,...
This paper explores a new technique of load modeling and estimation on distribution systems. With the emerging AMI technology real-time data about customer loads will be available and hence an estimate of loads on the distribution feeder can be made for system monitoring and control. With this data, a load model predicting the real-time load variations can be made. This paper elaborates the statistical...
