Pull Request: Grid Load Balancing Incentives Smart Contract

---

📌 Description

This PR implements a complete grid load balancing incentives smart contract that incentivizes load balancing on the Stellar network using Soroban, rewarding consumers for adjusting energy usage during peak demand periods. The contract facilitates demand response programs with secure reward distribution, smart meter verification, and comprehensive participation tracking.

closes #62

📌 Type of Change

• Documentation (updates to docs or comments)
• Bug fix (non-breaking change fixing issues)
• New feature (adds grid load balancing incentives functionality)
• Breaking change

🎯 Motivation and Context

This PR addresses the critical need for grid stability through demand response incentive programs that encourage consumers to reduce energy usage during peak demand periods. The implementation provides:

• Grid Load Balancing: Demand response events for managing peak energy demand
• Smart Meter Integration: Load reduction verification with baseline and actual meter readings
• Secure Rewards: Automatic incentive distribution using Stellar tokens
• Regulatory Compliance: Grid management standards compliance with FERC guidelines
• Audit Mechanisms: Complete transparency for reward distribution verification

Key Functions Implemented

• ✅ initialize(): Set up contract with grid operator roles and incentive rules
• ✅ register_consumer(): Register consumers for demand response programs
• ✅ start_event(): Initiate demand response events with target reductions
• ✅ verify_reduction(): Verify consumer load reduction via smart meter data
• ✅ distribute_rewards(): Distribute rewards to participating consumers
• ✅ Role-based Access: Grid operators initiate events, consumers participate
• ✅ Smart Meter Integration: Baseline vs actual usage verification with timestamps
• ✅ Comprehensive Testing: Full test coverage for all functionality and edge cases

🛠️ How to Test the Changes

1. Navigate to contract directory:

   cd soroban/contracts/grid-load-balancing-incentives

2. Run all tests:

   cargo test

3. Build the contract:

   make build
   # or directly with cargo
   cargo build

4. Build with Soroban CLI:

   make soroban-build
   # or stellar contract build
   stellar contract build

5. Run quality checks:

   make check-all

6. For production deployment (requires wasm32 target):

   # First install wasm target: rustup target add wasm32-unknown-unknown
   make optimize
