gtopt::PlanningLP class
#include <gtopt/planning_lp.hpp>

Linear programming model for power system planning.

Encapsulates a linear programming formulation of a power system planning problem, including system configurations, simulation scenarios, and solver options.

Public types

struct SddpSummary
Summary of the last SDDP solve (populated by the SDDP solver).
using phase_systems_t = StrongIndexVector<PhaseIndex, SystemLP>
using scene_phase_systems_t = StrongIndexVector<SceneIndex, phase_systems_t>
