Bug Fixes and Minor Updates

The following are the modifications: 1- W0 is now a parameter at the top layer of Renewables.PSSE.Wind model. This fixes the "circular equalities detected" error. 2- Added a Machine Base M_b parameter to the Wind, PV, and BESS models. This modification was the one previously displayed in Pull Request OpenIPSL#341.
