In PV analysis what exactly is meant by incremental MW transfer. Is it general load increase in sink through increase in 'lambda' or the equivalent load at every bus considered for monitoring?

In texts we have studied PV curves for a 2 bus system, where the voltage and the P-load at one of the buses is considered for plotting PV curve. But in a meshed system having multiple areas and zones, we select a source and a sink. What exactly does PSSE increase as the x-axis component for PV-curve that is termed as incremental MW transfer. What is that quantity or parameter that is changed to find the voltage at a particular bus?

is the load in the sink. After the sink load is incremented, a load flow solution will set the total output of the generation in the source, while the swing generator would take care of the losses. Now the base case is in a more loaded state. At his point contingencies are applied, load flow solved and monitored buses would have their voltage recorded. The process repeats until the source reached its maximum capacity to export power or the load flow does not solve, signaling that a potential voltage collapse has been uncovered. PSSE migth use linear factors techniques to accelerate computations of each contingency.
