by Solomon Nkrumah Adasah | Jul 21, 2025 | Control and Management, Energy Storage, Uncategorized

Battery Energy Storage Systems (BESS) are critical for maintaining the stability and reliability of microgrids. By balancing power supply, smoothing fluctuations, and regulating voltage and frequency, BESS play a key role in modern energy systems. However, safety concerns, such as fire, explosion, and large-scale outages due to battery malfunctions, pose significant risks to both personnel and property.

ADAC’s innovative solution addresses these safety challenges by integrating cutting-edge Battery Digital Twin technology to provide real-time fault detection and diagnosis for BESS. By combining the COMSOL Electrochemical Model with the Physics-Based Equivalent Circuit Model (PECM), our system simulates both the internal processes of the battery and its electrical behavior, ensuring accurate and fast fault tracking.

Key Features:

Integrated Battery Digital Twin: Combines electrochemical and circuit models for real-time, comprehensive battery performance simulation.
Fuzzy Logic Fault Detection: Uses fuzzy logic to estimate changes in battery parameters, detecting faults at their incipient stages for early intervention.
Intelligent Parameter Identification: The system processes fault data to train an intelligent algorithm that monitors battery health in real-time. By mapping changes in battery parameters to emerging faults, the system ensures timely detection.
Real-Time Monitoring: Continuously tracks battery conditions, such as current and temperature, providing ongoing health assessments and immediate identification of potential issues.
Fault Simulation & Prevention: Simulates battery performance under various fault scenarios, improving detection accuracy and preventing failures.

Results:

ADAC Hardware-in-Loop (HIL) Platform

To showcase our work, we have set up a Hardware-in-Loop (HIL) platform to demonstrate the integration of Energy Management Systems (EMS) and Battery Fault Simulation.
Dynamic energy management algorithms run on Raspberry Pi microcontrollers, enabling real-time microgrid scheduling visualized via a microgrid sandbox. The Battery Fault Simulator monitors battery status, while real-time demand and supply data are fed into big data analytics to predict and adjust the system’s next steps.
By combining HIL and Software-in-Loop (SIL) methods, this platform effectively demonstrates the feasibility of our research in dynamic energy management and Battery Fault Detection and Diagnosis (BIF-DD).

Hierarchical Collaborative Distributed Energy Management Systems (H-CoDEMS)

by Solomon Nkrumah Adasah | Jul 19, 2025 | Control and Management, Smart Grid, Uncategorized

In an era where climate-driven disasters and energy disruptions are becoming more frequent and severe, building a power grid that is intelligent, resilient, and adaptive is no longer a luxury—it’s a necessity. Conventional, centrally controlled energy systems often fall short in times of crisis, struggling with rigidity, bottlenecks, and single points of failure.

At ADAC Lab, we are pioneering the Hierarchical Collaborative Distributed Energy Management System (H-CoDEMS)—a cutting-edge framework designed to revolutionize how microgrids operate and coordinate. H-CoDEMS adopts a self-organizing, hierarchical architecture that enables scalable, fast, and resilient energy management across distributed energy resources. By leveraging situational awareness and a distributed consensus-based control strategy, H-CoDEMS allows microgrids to make intelligent, cooperative decisions in real time. This makes it exceptionally effective in a range of critical applications:

Disaster Relief: Rapidly restores power to essential services such as hospitals, emergency operations centers, and communication networks, even when centralized infrastructure is compromised.
Networked Microgrids: Enables seamless coordination and reconfiguration across interconnected microgrids, enhancing resilience and operational efficiency.
Virtual Power Plants (VPPs): Coordinates distributed energy resources to act as a unified, flexible grid asset, improving reliability and grid balance.

Dynamic Energy Management System (D-EMS)

by Solomon Nkrumah Adasah | Jul 19, 2025 | Uncategorized

The electric power system is vital to national infrastructure, yet vulnerable to natural disasters. Traditional centralized control strategies are prone to single points of failure and high computational costs. In contrast, distributed energy management systems (EMS) offer improved resilience by reducing failure risks and easing communication bottlenecks—crucial for emergency response.

During disasters, when grid infrastructure is damaged or destroyed, distributed EMS-enabled microgrids can restore power to critical facilities like hospitals and emergency centers. However, these systems face challenges in scalability, convergence speed, and real-time reconfigurability—especially in large-scale, time-sensitive scenarios.

To overcome the state of the art challenges, our research lab (ADAC) has proposed a novel Dynamic Energy Management System (D-EMS) framework for microgrids to perform self-reorganization for the Hierarchical Collaborative Distributed Energy Management Systems (H-CoDEMS) automatically and in a hierarchical structure to achieve log-scale scalability, fast convergence and reconfigurability. Leveraging situational awareness and intelligent management, the system adopts a hierarchical distributed consensus framework to enable fast and collaborative decision-making. This ensures efficient power system scheduling operations, allowing for rapid power restoration and ultimately saving lives.
