LP-based capacity optimization
Define your energy requirements and the optimizer designs the optimal system. Quick Design mode asks minimal questions and produces results in seconds. Full auto-design uses Linear Programming (LP) to minimize LCOE while meeting renewable targets.
- Quick Design: minimal inputs, results in seconds
- LP optimizer: minimum-cost PV + Battery + Wind sizing
- 5 backup strategies for constrained projects
- Outputs: LCOE, IRR, Payback, Renewable Fraction
Real-time dispatch optimization
Go beyond static simulation with Model Predictive Control. The MPC controller continuously re-optimizes dispatch decisions using actual system state — battery SOC, degradation, and real generation data. Adaptive horizons expand or contract based on forecast confidence.
- Adaptive horizon: 12-96 hours based on conditions
- State feedback with SOC/SOH correction
- Degradation-aware constraint tightening
- 12 tracking metrics per timestep
