I have installed R2013b along with Simscape version 3.10. I need to simulate power electronic circuits. I typedpowerlib in command window to open the simpowersystems library, but got the following error: Undefined function or variable 'powerlib'.

You can check the SimElectronics library, that comes with basic Simscape (use thesimscape command in the MATLAB console), and see if the included blocks will be sufficient for your modelling goals. Here are some relevant links to SimElectronics blocks in Simscape:
