Sharp formulations of nonconvex piecewise linear functions to solve the economic dispatch problem with valve-point effects

•New mathematical programming techniques to solve the nonconvex ED are proposed.•A new breakpoint assignment method for piecewise linear approximations is presented.•CC, DCC, MC, Inc, and Log techniques are used to model the ED with valve effects.•Sharp and locally ideal properties of the mixed-inte...
