If users want to simulate an increase on the downstream load of a device, select the item with a _Load suffix in the Change Variables option to open the window on the next figure.

Window to change loading

Changing the loading of a device allows the Power Flow Module to calculate the resulting currents of increasing or decreasing a load. If users increase the value of active power of RL1_Load, it also increases the block load delimited by devices RL1 and RL2. As a result of this increase, the Power Flow Module recalculates the currents for device RL1 itself and for device SUB01.5201. Currents on all other devices remain unchanged.
