Installation of AC/DC Microgrid System at Birmingham City University

Ecosense supplied and installed an AC/DC Microgrid Training and Research System at Birmingham City University, enabling hands-on experimentation in microgrid operation, renewable energy integration, energy storage, and power electronics through a controlled laboratory-scale platform.

Introduction

Ecosense Sustainable Solutions successfully supplied and commissioned an AC/DC Microgrid Training and Research System with programmable AC and DC loads at Birmingham City University. The installation strengthens the university’s laboratory infrastructure for advanced teaching and applied research in power electronics, renewable energy integration, and microgrid control. The system is designed exclusively for educational and research use in a controlled university laboratory environment and supports both grid-connected and islanded modes of operation.

About the Installation

The AC/DC Microgrid system was installed as a complete, integrated laboratory platform comprising energy source emulators, power electronic converters, programmable loads, sensing and protection hardware, and a PC-based supervisory control environment. The system architecture is centred around a common DC link, enabling controlled power flow between simulated renewable sources, energy storage, AC and DC loads, and the utility grid.

The installation includes full hardware setup, electrical integration, safety interlocks, and software deployment for on-grid and off-grid operation. All modules are physically and electrically accessible, allowing students and researchers to perform repeatable experiments while adhering to laboratory safety regulations.
