Define load center

Short answer

A load center is the point in a supply area where the total load can be considered concentrated, found as the center of gravity of loads using weighted average coordinates. Placing the substation at this point minimizes feeder lengths, voltage drop, and I²R losses.

With respect to a distribution system, define load center.

A load center is the point in a supply area at which the total load can be considered concentrated. It is found as the "centre of gravity" of the loads, with coordinates xˉ=∑Pixi/∑Pi\bar x = \sum P_ix_i / \sum P_i and yˉ=∑Piyi/∑Pi\bar y = \sum P_iy_i / \sum P_i.

The substation or distribution transformer is placed at or near the load center. This keeps the feeder lengths, voltage drop and I2RI^2R losses to a minimum.
