Load Balancing and Load Management

It has been observed in which the load on all three phases of a distribution line and between the feeders is not balanced. This output in increased current in the heavily loaded line along with increased line losses. If the loads on each phase or between feeders are redistributed, the losses will be reduced. Shifting of consumers for the overloaded phase should be completed to decrease the imbalance in the system. The best technique to identify unbalancing is to construct current duration curves for all three phases.

In the scenario of overloaded distribution systems, load management plays an extremely significant role for reduction of technical losses. Load management is significant to ensure supply to feeders feeding critical emergency loads, curtailing supply to other loads and shifting of loads among feeders.To avoid overloading of lines and transformers in real time mode, modern features such as distribution automation might be incorporated. Distribution automation along with SCADA (Supervisory Control and Data Acquisition System) is a significant tool for load management that should be introduced.
