1. For a deterministic case, you want to use the default values for contingency constraint parameters in the xGen data, since they are not relevant when there is a single state per period. Technically, in the implementation they are independent, so it is possible to include both, but the contingency constraints make no sense and have no impact on the deterministic case. See the footnote on p. 35 of the MOST User’s Manual <http://www.pserc.cornell.edu/matpower/docs/MOST-manual-1.0.1.pdf>.
2. Yes. See equations (7.2)–(7.5) in the MATPOWER User’s Manual <http://www.pserc.cornell.edu/matpower/docs/MATPOWER-manual-7.0b1.pdf> for the formulation.
