NammaGrid: Community-level AI Power Optimization System Bringing Smart Grids to Neighborhoods

NammaGrid is a Streamlit-based community power optimization intelligent agent system. It provides safe and sustainable energy management solutions for the Malleshwaram community in Bangalore, India, using synthetic demand modeling, peak risk prediction, rule-based reasoning, and explainable AI technologies. The project’s core philosophy is "Optimize, don't cut off", aiming to intelligently balance community power loads and avoid the drawbacks of traditional load shedding.

Peak power demand in modern cities often occurs during overlapping periods of residential evening use, commercial activities, cooling equipment operation, street lighting, and public facility needs. Traditional management methods mostly rely on load shedding, which disrupts residents’ lives and business operations. NammaGrid proposes a hyper-local power optimization agent solution to balance loads without interrupting power supply.

Synthetic Demand Model

Simulates real community power consumption patterns, considering dimensions such as residential evening peaks, commercial activity patterns, mixed area overlaps, street lighting loads, public infrastructure, flexible and critical loads, and transformer pressure proxies.

Demand Estimation Engine

Estimates hourly power demand based on time factors, seasonal changes, user count, and regional characteristics.

Rule-based Expert Layer

Detects scenarios like evening peaks, commercial/mixed area demand, street lighting loads, transformer pressure warnings, high critical load situations, and low-risk conditions.

Utility-based Intelligent Agent

Ranks action plans by scoring dimensions including peak reduction, cost savings, infrastructure relief, carbon emission reduction, comfort disruption penalties, and safety risk penalties.

Constraint Handling Mechanism

Hard constraints: Prohibit complete power outages and prioritize power supply for critical facilities like hospitals.

NammaGrid has a built-in interpretability module. The dashboard displays triggered rules, score meanings, winning actions, trade-off analysis, and reasons for avoiding power outages, ensuring transparent AI decisions and building user trust.

The project aligns with the United Nations Sustainable Development Goals (SDG):

• SDG7: Optimizing power usage supports clean energy access and reduces reliance on high-carbon emission peak power sources;
• SDG11: Improves urban infrastructure resilience and enhances communities’ ability to cope with power fluctuations;
• SDG12: Encourages responsible power consumption through demand-side management;
• SDG13: Reduces peak carbon emission pressure and lowers overall carbon footprint.

Uses a Python tech stack with core components including main.py (Streamlit main application), data_model.py (synthetic data modeling), and agent.py (decision agent). Users can adjust parameters like area type, time period, and season, and the system generates real-time results for synthetic demand patterns, load predictions, rule triggering status, and action ranking.

Current Limitations

It is a student demonstration project using synthetic data and assumptions instead of real-time operational data; results are for explanatory and educational purposes.

Future Expansion

Plans include integrating real-time data, fusing multi-source signals, monitoring equipment health, adding user feedback loops, and exporting planning reports.

NammaGrid demonstrates the value of AI in solving real community problems:

1. Prioritizes interpretability to ensure transparent AI decisions for public services;
2. Ensures reliable solutions through safety constraints;
3. Balances multiple objectives including cost, comfort, safety, and environmental impact;
4. Aligns technical design with SDG goals. It provides a reference architecture for smart city and energy management developers, proving that simple rules plus utility models can produce practical AI solutions.
