Design and Simulation of a Power System with Multiple Renewable Sources - Engineering Guide
1. Introduction
As global energy demand increases, integrating multiple renewable energy sources (RES) like solar, wind, and hydro into the power grid becomes essential for sustainability. This project focuses on designing and simulating a hybrid power system that combines various renewables to ensure reliable and efficient energy supply.
2. Objectives
- Design a hybrid power system using solar, wind, and other
renewable sources.
- Simulate power generation, load balancing, and energy storage.
- Analyze system performance under variable conditions.
- Evaluate the cost-effectiveness and reliability of the system.
3. Components Required
- Solar panels
- Wind turbine model
- Hydro or other renewable energy models
- Battery storage system
- Inverters and charge controllers
- Load (resistive/AC models)
- MATLAB/Simulink or PSCAD for simulation
- Sensors and microcontroller (if hardware-based prototype is included)
4. System Design
The system architecture includes:
- Renewable sources connected to a common DC bus.
- Energy storage (battery bank) for load leveling.
- Inverter converts DC to AC for grid/load compatibility.
- Load management via intelligent control or programmed scenarios.
- Monitoring and simulation of real-time data using software tools.
5. Simulation Details
