Termination

Solver: CBC 2.10.3 · Status: Optimal solution found (within gap tolerance) · optimal innerhalb Toleranz — hoechstens 0.55 CHF ueber dem theoretischen Optimum
Abbruch-Schranke 0.42 CHF · relative Rest-Gap 0.0 % — deren Nenner ist der Netto-Zielwert (Bezugskosten minus Einspeiseerloese) und wird bei hohem PV-Anteil klein, was den Prozentwert aufblaeht; massgeblich ist der CHF-Betrag. Die untere Schranke unterstellt zudem stufenlos schaltbare Aktoren (LP-Relaxation der 139 Binaervariablen) und ist mit On/Off-Hardware nicht erreichbar — der reale Abstand zum Optimum ist kleiner.
Runtime: total 1.440 s (Modellbau 0.025 s, Solver-Call 1.407 s, CBC-Wallclock 0.32 s) · Modell: 1902 Variablen (139 binaer), 819 Constraints · untere Schranke 1875.1730 CHF
