Experimental Testbed for Hybrid Energy Systems
This project showcases an innovative experimental testbed designed to validate a hybrid topology combining conventional and reverse DC‑coupling. It simulates the dynamic energy flows within a utility‑scale hybrid system, integrating solar PV generation with battery storage.
Our objective is to assess the feasibility and stability of controlled power transfer among solar panels, battery, and the grid via multiple inverters, demonstrating coordinated control in AC‑coupled systems with active DC bus interaction.
Core Features
A Platform Built for Innovation
This testbed isn’t just hardware; it’s a complete ecosystem for validating the next generation of hybrid energy systems.
Conventional DC‑Coupling
PV directly charges the battery via a dedicated DC‑DC converter, ensuring maximum efficiency for energy capture and storage.
Reverse DC‑Coupling
Stored battery energy is fed into the solar inverter’s DC bus, enabling highly flexible and grid‑responsive power dispatch.
Four‑Way Power Flows
Dynamically route energy: PV to Grid, PV to Battery, Battery to Grid, or a coordinated combination of all assets simultaneously.
Advanced SCADA Control
Features SCADA‑controlled dispatch with Python for complex logic and a Node‑RED dashboard for real‑time monitoring and interaction.
Comprehensive Hardware
Equipped with 1 kW inverters, PZEM sensors, and a Victron SmartShunt for precise measurement and robust data logging.
Utility‑Scale Logic
A small‑scale testbed meticulously designed to replicate the complex control logic and behavior of large, MW‑scale power plants.
Case Study
The AC-RES Pilot Project
This is where theory met the grid. Our prototype deployment proved that a smarter hybrid architecture can eliminate compromises and set a new benchmark for performance.
The Mission
From Blueprint to Reality
-
The Challenge: Conventional systems force a choice between DC-coupling's efficiency and AC-coupling's flexibility. Our goal was to deliver both, without compromise.
-
The Solution: We deployed the first full-scale AC-RES prototype, integrating our patented DC-DC converter and advanced control algorithms to capture lost energy and ensure 24/7 asset availability.
-
The Outcome: The pilot successfully validated the AC-RES architecture, showing significant gains in energy capture, superior system uptime, and enhanced grid support capabilities.
