Resumen
The behavior of DC load flow formulations when they are used in economic
dispatch and nodal pricing models is discussed. It is demonstrated that nonnegative
prices in these models are sufficient to guarantee global optimality of any
local optimum, even if the feasible region is not convex, and so a negative nodal price
is an indicator of a possible loss in optimality.We also discuss the possible effect that
negative prices might have on algorithms that assume this convexity.
