Industrial, Residential, and Commercial Demands Relationship With Load Components in Reconfigurable Distribution Grids

Power system optimization may involve reducing network losses, minimizing voltage deviations, decreasing line failures, and lowering maintenance costs. Achieving these objectives is possible through the optimal reconfiguration of distribution networks. Line switching is a key method for modifying the distribution network configuration, aiming to minimize losses, improve voltage stability, reduce fault currents, and implement cost-effective maintenance procedures. The power of load, a crucial factor in this process, requires more accurate modeling of the demand side to depict the behavior of electricity consumers. However, load fluctuates with changes in voltage magnitude, and this fluctuation is influenced by the type of consumer. Additionally, load is characterized by its impedance, current, and power. Consequently, identifying the relationship between these elements and the type of load is pivotal, especially when specific load components are accessible. This critical aspect has largely been unexplored in related studies on reconfiguration. Therefore, this article addresses this gap by mathematically formulating the correlation between demand components and load categories. The formulations proposed in this article contribute to more efficient and flexible reconfiguration frameworks, enhancing our understanding about the intricate dynamics of distribution system reconfiguration.
