I happen to simulate a Hybrid renewable energy system consisting of various converters. I often encounter the problem of very long execution time for running a 5-second simulation. I have installed Matlab in my laptop with Intel i-5 processor and with 4-GB RAM.
I would be grateful to you if any one could suggest me some solution of how do I over come the above problem.
MatLab offers a "toolbox" to let you use parallel processing. Some options are built into the base program.
You can check our eMEGAsim, eDRIVEsim and eFPGAsim real-time simulators capable to simulate any power electronic systems with very small time step (from 200 nanos and up) using Simulink and SimPowerSystems. PC (INTEL with 14 cores to 32 cores) and FPGA-based simulator can be used to accelerate simulation at a speed faster than real-time (if no external equipment is connected with the simulator) or in hard real-time for HIL tests with actual control systems. FPGA can execute models defined with SimPowerSystem, PLECS or PSIM
Try to run your HPS in rapid-accelerator mode, it will sufficiently improve your speed
If your model can be built with Simulink Coder, you can use xMOD software (www.xmodsoftware.com) to execute your model in multicore (subsystem per thread basis).
