# 🇬🇭 PyPSA-Ghana **Open-source power system research model for Ghana — vanilla PyPSA, real data, reproducible science.** --- ## What this is PyPSA-Ghana is a research-grade power system model for Ghana, built on vanilla PyPSA. It uses real hourly demand data constructed from Ghana's Wholesale Electricity Market (WEM) bulletins and a validated generator fleet from the Energy Commission's National Energy Statistical Bulletin. This repository is the **research layer** of a two-repo Ghana modelling framework: | Repo | Purpose | | ----------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------- | | **pypsa-gh** | Ghana configuration for PyPSA-Earth — automated network building, ERA5 renewable potential, infrastructure planning | | **pypsa-ghana** ← you are here | Vanilla PyPSA research analysis — real WEM demand, validated dispatch, contingencies, LEAP integration, paper | --- ## What it does ``` pypsa-gh (PyPSA-Earth) pypsa-ghana (this repo) ────────────────────── ─────────────────────── ERA5 solar/wind profiles ──────► Renewable capacity factors Network topology (6 nodes) ──────► Transmission constraints Real WEM hourly demand (2024) Validated generator fleet Baseline dispatch optimisation SCOPF contingency analysis Emissions tracking LEAP demand scenarios 2030-2070 Least-cost capacity expansion ▼ ──────► Validated results feed back to pypsa-gh ``` --- ## Research programme ### Phase 1 — 2024 Baseline (current) - 8,760-hour demand profile constructed from WEM Bulletins Issues 91–102 - Generator fleet: 20+ plants, real marginal costs from fuel prices and heat rates - Dispatch optimisation validated against Energy Commission Statistical …
