🎯 Mission: Creating the world’s first comprehensive, open-source benchmarking platform for Home Energy Management Systems (HEMS), enabling transparent comparison and optimization of distributed energy resources across global markets.
🌍 Market Context & Opportunity
The distributed energy resources market is experiencing unprecedented growth, creating urgent need for standardized evaluation frameworks.
📈 Explosive Market Growth
Key Market Drivers:
- Solar PV: Projected to be the largest renewable source by 2030 (~80% of capacity growth) [IEA]
- Residential BESS: Growing from 3 GWh (2020) to 122 GWh (2030) in Europe alone [McKinsey & Company]
- Investment Surge: Falling costs + rising electricity prices + government incentives
🔄 The Three Challenge
Current HEMS evaluation suffers from fragmentation across three distinct domains:
🏗️ Framework Architecture
🔄 Complete Lifecycle Optimization
Our platform addresses the entire DER lifecycle through three integrated optimization phases:
| Phase | Time Horizon | Key Decisions | Optimization Focus |
|---|---|---|---|
| 📍 Location & Sizing | 1-15 years | Installation location, capacity | Cost reduction, backup power |
| 🏠 HEMS Evaluation | 1 day | Charging/discharging behavior | Self-consumption, comfort |
| ⚡ Grid Support | 1 year | VPP capacity allocation | Additional revenue streams |
🤖 Systematic Modeling Framework
Advanced Capabilities:
- 🎯 Uncertainty Quantification: PV generation, load forecasting, price volatility
- 🧠 AI Integration: Machine learning-based optimization algorithms
- 📊 Multi-Objective: Cost, reliability, comfort, environmental impact
- ⚡ Real-Time Control: Adaptive strategies for dynamic conditions
