Hi everybody I´m trying to emulate the behavior of home energy consumption but I do not know how to make that variation of power comsumption with SPS, until now I have just emulate a comsumption with a steady power with a Series RLC Load monophase, but as I wrote you in the firsts lines of this paragraph I need to represent a real behavior of the use of the energy at a typical spanish home. That´s why I need to make than the power comsumption will goes up, down and in some moments o time it be steady. Does anyone has the answer to solve this trouble?. Take in count that I only use DC voltaje monophase to supply energy to the house.

Yes -- there is a Three-Phase Dynamic Load block in which you can specify your own active power (P) and reactive power (Q) time series data.

Notice that the help page for the block mentions:

"If External control of PQ is selected, a Simulink input, labeled PQ, appears. This input is used to control the active and reactive powers of the load from a vector of two signals [P, Q]."

For some reason there doesn't seem to be a single-phase load block in the SimPowerSystems library itself, though there is the shipping example power_1phdynamicload. I'd use the block in this example.

@Sebastian Castro i need to import P and Q data in the simulation to simulate a consumption of a house. I just dont't know how to use the Externa control of PQ in this model power_1phdynamicload. Could you please explai it to me?
