# **Simulation of Hybrid PPO–Q Learning Based MPPT and Grid Voltage–Current Regulation for a 5.3 kW Grid-Connected Photovoltaic System (MATLAB/Simulink)** ## Project Description I am looking for an experienced **MATLAB/Simulink** expert with knowledge of **Power Electronics, Reinforcement Learning (PPO & Q-Learning), MPPT, and Grid-Connected PV Systems** to develop a **simulation-only project**. The objective is to design and simulate a **5.3 kW grid-connected photovoltaic (PV) system** using a **Hybrid PPO–Q Learning-based MPPT controller**. The controller should maximize solar power extraction while regulating grid voltage and current under varying irradiance and temperature conditions. The proposed controller should provide fast dynamic response, high MPPT efficiency, low steady-state oscillation, stable DC-link voltage, and maintain grid current THD within IEEE standards. **Note:** This is strictly a **MATLAB/Simulink simulation project**. No hardware implementation is required. ## Scope of Work Develop a complete MATLAB/Simulink model including: * PV Array (5.3 kW) * Hybrid PPO–Q Learning MPPT * DC–DC Converter * DC-Link * Three-Phase VSI * PLL-Based Grid Synchronization * Grid-Connected System * Reinforcement Learning Training and Testing * Performance comparison with P&O, Incremental Conductance (INC), PPO-only, and Q-Learning-only methods. ## Required Results ### PV & MPPT * PV Voltage, Current, Power * MPPT Efficiency * Tracking Time * Steady-State Oscillation * Duty Cycle ### DC–DC Converter * Input/Output Voltage * Output Current * DC-Link Voltage * Voltage & Current Ripple * Converter Efficiency ### Inverter * Three-Phase Output Voltage * Output Current * PWM Gate Pulses ### Grid Performance * Grid Voltage * Grid Current * Current Tracking Error * Active Power (P) * Reactive Power (Q) * Power Factor * PLL Synchronization ### Power Quality * Grid Current THD (FFT) * Grid Voltage THD (FFT) * Harmonic Spectrum ### Reinforcement Learning * PPO Reward vs Episode * Q-Learning Convergence * Policy/Training Loss * Learning Curve Comparison ### Dynamic Performance * Irradiance Change * Temperature Change * Partial Shading * Load Change * Grid Voltage Sag/Swell * Startup & Shutdown ### Comparative Analysis Compare with: * P&O * Incremental Conductance (INC) * PPO Only * Q-Learning Only Include comparison of: * MPPT Efficiency * Tracking Time * THD * Power Factor * Dynamic Response ### Stability & Efficiency * Rise Time * Settling Time * Overshoot * Steady-State Error * Daily Energy Harvested * Overall System Efficiency ## Deliverables * MATLAB/Simulink (.slx) model * MATLAB (.m) files * RL implementation * Well-commented model * Simulation graphs and waveforms * FFT/THD analysis * Performance comparison tables * Short technical report explaining the methodology and results ## Required Skills * MATLAB/Simulink * Simscape Electrical * Reinforcement Learning (PPO & Q-Learning) * MPPT Algorithms * Grid-Connected PV Systems * Power Electronics * Control Systems * Three-Phase Inverters * Renewable Energy Please apply only if you have prior experience with **MATLAB/Simulink**, **Reinforcement Learning**, and **Grid-Connected PV System simulations**.
