System-Level Power Simulation Diagrams

I have to complete a power-system simulation task and need a partner to build it from scratch. The work must stay at the system level and include both a Causal Loop Diagram (CLD) and a Stock-and-Flow Diagram (SFD). Once the base model is ready, the assignment continues into model validation, scenario-based intervention, and optimisation, so the files you hand over should already be set up for those steps.

Buatlah story model sederhana (agar tidak menggunakan model template yang diajarkan), CLD, dan SFD, lakukan validasi visual dan statistik, serta
lakukan prediksi dengan tata waktu yang ditetapkan pemodel, serta lakukan optimasi model (boleh dengan data dan threshold dummy yang rasional).
Model memuat fungsi sesuai dengan sistem yang ditirukan.

Deliverables
• System-level CLD (editable source + image)
• System-level SFD linked to the CLD
• Brief validation write-up showing consistency with real-world data or literature benchmarks
• Two intervention scenarios with outcome discussion
• An optimisation run that demonstrates measurable improvement and explains the chosen objective function
• Short report (max. 5 pages) tying everything together

Native model files must open without issues in the software you choose (Vensim, Stella, PowerSim, or an equivalent system-dynamics tool).
