Question
I´m doing a circuit or model with a cell array and a battery in order to simulate the consumption of a home, but I have not get to do it because SPS use only loads RLC and and it works with a RMS voltage and I want to connect it to a DC supply directly, what would you do in order to solve this issue. If we try to connect the software does not allow it, because seems be an incompatibility beetwen both softwares SPS and SCS. I´ve tried to use a R Load from SCS and I have not get solve it yet, I am thinking than it is not good to combine SPS with SIMELECTRONICS because appear more issues, what can I do for modelize a load consumption in DC?

First off, SimPowerSystems Specialized Technology has the blocks (I think) you need:

  1. DC Voltage Source
  2. Series RLC Load or Series RLC Branch -- just set the L and C values (or reactive power Q, depending on which block) to 0 and you have yourself a resistor.

Also, if there are other Simscape/SimElectronics blocks that you absolutely must have, there are interface blocks between Simscape and SimPowerSystems Specialized Technology. I wouldn't recommend using these unless you really have to, as they go through Simulink signals first and therefore affect the "physicality" or numerical stability of the model... but they exist.
