LoadΒΆ
The Load components attach to a single bus and represent a demand for the
Bus carrier they are connected to. With inverted sign, they can also be used
to model an exogenous supply. For "AC" buses, they act as a PQ load. If \(p>0\)
the load is consuming active power from the bus and if \(q>0\) it is consuming
reactive power (i.e. behaving like an inductor).
When to use Generator instead?
Use the Generator component with a negative sign and negative marginal_cost to model elastic demands following a linear demand curve or to represent a consumption at a given price like shown in the example about demand and supply bids.
