State Estimation for Load Allocation in Distribution Power Systems

Considering the large number of customers, local online monitoring is not conceivable. Alternatively, customers’ load could be estimated using some measurements in the main station and also on important points of power grid. Therefore, the customers’ load allocation is a consequential part in automated distribution power systems. In this paper, the load allocation is developed using average demand of each customer and also the classification curve of customers. The mentioned approach could yield a reliable estimation for each load. Application of this method to two real power systems, comparing estimations with the real measured values ascertains a satisfactory performance.
