Dr. Nauman Zaffar Butt in the Electrical Engineering department leads our efforts on photovoltaics which has now crossed over into the realm of agriculture, to produce the budding field of agrivoltaics. Powering agricultural farms through solar energy requires creative designs in both the solar cells as well as how solar cells will be integrated into a solar system that can power agri-farms.
Dr. Butt's PhD student Hassan Imran has now produced an amazing body of work that helps achieve both of these tasks. Novel materials, novel designs of the heterofacial structure of solar cells and employing two-dimensional layers of graphene or carbon nano-tubes can boost the performance of solar cells, achieving almost thermodynamically maximum efficiencies. Creative ways to interface silicon based and organic-inorganic solar cell technologies helps achieve the best of both worlds.
Finally, Hassan has mathematically modeled the role of soil and orientation of solar panels, in achieving high efficiency crop yield from solar enhanced farmlands. This work has immense implications for the country which calls for innovative solutions to address critical problems at the food-energy-water confluence.
The quality of his work is evidenced by the four articles published in the world's leading journal on this topic:
- The IEEE Transactions on Electron Devices [here, here, here and here],
- The IEEE Journal of Photovoltaics [here],
- Solar Energy [here] and
- Renewable Energy [here],
- along with several conference proceedings.
The Water-Food-Energy nexus remains one of the six forefront areas being pursued at the Syed Babar Ali School of Science and Engineering.

In a world increasingly reliant on electricity, power outages can bring daily life to a grinding halt. However, an innovative research by Chaudhry Talha Hassan and Dr Tariq Mahmood Jadoon from the Department of Electrical Engineering significantly accelerated the restoration of electric power after a major blackout by improving the resilience of smart grids. These grids integrate many distributed energy resources (DERs) such as solar panels, wind turbines and energy storage systems.
Shortly, after the study's publication in IEEE Xplore in August 2023, Sir Ganga Ram Hospital in Lahore experienced a power outage due to alleged mismanagement, forcing doctors to use torchlight to complete their procedures. A similar incident had occurred at Services Hospital Lahore less than a month earlier, impeding patient care. More recently, during the Sindh flash floods, the preservation of the Guddu power station played a crucial role in preventing a blackout that could have impacted 25% of Pakistan's population. These recurrent incidents underscore the timeliness of this research, where critical loads in a distribution feeder can be restored by harnessing power from neighboring DERs considering the power network as a cyber-physical power system.
When an entire city or neighborhood experiences an abrupt power loss, the urgency to restore electricity to critical facilities such as hospitals and emergency services is paramount. Bulk power distribution networks typically have a limited number of switchable lines and loads. This limitation can make it challenging to restore power, particularly in situations where many inductive loads are switched on simultaneously.
This is where the innovative concept of "microgrids" comes into play. The researchers have proposed the creation of these smaller, self-sustaining power networks that can swiftly bring power back to affected areas. Unlike the conventional top-to-bottom approach, the research emphasizes harnessing smart grids, using communication tech, reconfiguring networks, and integrating DERs. This ensures the rapid restoration of power to critical loads while addressing challenges like frequency control and practical factors such as switch types and communication constraints.
Inverter-dominated smart grids face unique challenges related to dynamic stability and lower inertia. The research introduces a multi-layered framework that integrates cyber-networks into the restoration process. It also emphasises the importance of monitoring the health of energy storage systems, ensuring safe charging and discharging strategies, and imposing constraints on frequency and voltage to maintain grid stability.
Moreover, the act of restoring power can sometimes introduce problems like system overload. To mitigate these potential issues, the study incorporates dynamic stability constraints into the restoration process, ensuring that the system remains stable even during the reconnection of numerous power sources.
To validate their concepts, the researchers employed computer simulations. These simulations create a virtual representation of the power system, allowing the team to experiment with different strategies without affecting the actual electricity supply.
The research sheds light on the crucial role of synchronous generators as black-start distributed generators (DGs) for service restoration. Unlike renewable energy sources, high-inertia diesel generators can provide reliable power during emergencies. By including backup generators (BUGs) as dispatchable DGs in microgrids, the research demonstrates an innovative approach to harnessing power from non-dispatchable sources, enhancing microgrid stability, and expanding coverage.
Talha's research promises a more efficient and resilient future for power restoration. By harnessing the power of microgrids and cyber-physical systems, this approach promises to revolutionise how we think about restoring electricity in the face of adversity. As our world increasingly relies on electricity, innovations like these are essential for ensuring that the lights stay on even when the grid faces its darkest hours.
Huzaifa Rauf, a brilliant PhD scholar from the Department of…
Huzaifa Rauf, a brilliant PhD scholar from the Department of Electrical Engineering, has within a year earned two significant accolades - the prestigious “Center for Advanced Life Cycle Engineering (CALCE) at the University of Maryland Awards” for his outstanding performance and lasting contribution on “Safe Energy Storage Research”, and the publication of his research paper in the renowned Elsevier’s “Journal for Energy Storage”.
The rise and widespread adoption of electric vehicles (EVs) in recent decades has been primarily fueled by advancements in battery and power technologies and the urgent need to curb greenhouse gas emissions. However, unlike traditional fuel-driven vehicles, EVs face a significant challenge—the degradation of their batteries—which limits their overall lifespan. This issue is particularly concerning considering the resource-intensive nature of battery production, as short-lived batteries have an unintended adverse effect on the environment. Recognising this critical problem, Huzaifa is actively involved in a research group at SSE, LUMS Energy Institute, dedicated to enhancing the area of renewable energy analytics, smart grids, and energy efficiency.
During Huzaifa’s time as a visiting scholar at the University of Maryland, he worked under the supervision of Prof Michael Pecht (member SBASSE advisory board) and Dr Michael David Osterman at CALCE. His dedication and expertise in applying AI and machine learning for reliability improvement in electric vehicle batteries were instrumental in earning him the CALCE award, making him the first visiting PhD from any country to receive this prestigious honour from the Centre. As part of the award, Huzaifa also received a funding grant of $5,000, acknowledging his exceptional research accomplishments.
“Having worked at the initial phase of the battery degradation, swelling and thermal runaway project, I am confident that this stream is going to make a significant impact in domain of energy storage.” Huzaifa expressed great enthusiasm for having his work recognised.
In addition to the research award, Huzaifa has also published a paper titled "A Novel Smart Feature Selection Strategy of Lithium-ion Battery Degradation Modelling for Electric Vehicles Based on Modern Machine Learning Algorithms", under the supervision of Dr Naveed Arshad, founder LUMS Energy Institute.
The paper highlights the importance of accurately predicting battery capacity loss to ensure the batteries' longevity, safety, and reliable operation. To achieve this, the researchers propose a smart feature selection (SFS) strategy-based machine learning framework. The SFS method selects relevant input parameters from battery data from the current and previous time steps, which are then utilized for model training and testing.
The results demonstrate that the proposed SFS method, in combination with various machine learning algorithms, significantly enhances the prediction accuracy and reduces the mean absolute error for battery capacity loss. The paper also emphasizes the importance of predicting a battery calendar, the degradation of a battery’s life over time whether or not it’s used, and cyclic loss, the gradual decrease in battery capacity caused by repeated charge and discharge cycles. Furthermore, it showcases the improved performance achieved by combining the SFS method with machine learning algorithms such as Gaussian Process Regression (GPR), random forest (RF), and XGBoost. This research presents a novel approach to feature selection-based machine learning for independently predicting battery calendar and cyclic loss, making it a valuable contribution to the field.
The publication highlights Huzaifa’s innovative approach to selecting smart features in modelling lithium-ion battery degradation, which has significant implications for electric vehicle performance and longevity. The research paper stands as a testament to his commitment to advancing the field of safe energy storage.

As summer approaches, high temperatures in Pakistan bring a host of challenges beyond the physical discomfort of the heat. With frequent power outages plaguing the country’s energy grid, keeping cool and comfortable can be a struggle. Pakistan, like many other countries, is turning to renewable energy like rooftop solar panels and net metering to power homes and businesses. However, unlike technologically advanced countries, Pakistan does not have a distribution management system (DMS) to handle the influx of renewable energy from rooftop solar panels.
Dr Raheel Zafar, Assistant Professor from the Department of Electrical Engineering at LUMS, is working on solutions to help manage energy grids more efficiently and reliably, not only for Pakistan but globally. In 2023, he published two papers in IEEE Access, one as the first author of an international collaboration and the other one with his research assistant as the corresponding author. We will take a closer look at another one of Dr Raheel’s recently published papers in the reputed research journal, IEEE Transactions on Sustainable Energy titled Multi-Timescale Coordinated Control with Optimal Network Reconfiguration using Battery Storage Systems in Smart Distribution Grids
The paper proposes a new optimization framework to improve the performance of power distribution networks, which are responsible for bringing electricity from the transmission system to consumers. While the framework was developed by Dr Raheel, the co-author Dr Hemanshu R. Pota, Associate Professor at the University of New South Wales Canberra in Australia, provided valuable input during the structuring and revision stages of the article.
The paper deals with feeder reconfiguration, which involves changing the network’s topology by opening and closing switches to modify the connections between parts of the network. Dr Raheel proposes the co-optimization of feeder reconfiguration, creating a plan to schedule the use of (1) traditional voltage regulating devices, such as the on-load tap changer (OLTCs), to regulate the voltage of the traditional power grid, and (2) utility-scale distributed energy resources like battery energy storage systems and photovoltaic (solar energy) inverter.
To determine the optimal coordination between these different sources of power, Dr Raheel used a mathematical model called “mixed-integer second-order cone program”. This was solved using the GAMS software, an abbreviation for General Algebraic Modeling System, to find the best solution for the power grid, or “global optimum”, by exploring possible solutions and identifying the combinations that produce the best outcomes. Furthermore, the feasibility of the solution was tested using the Distribution System Simulator (OpenDSS) software. The model calculated an optimal switching plan on a daily basis, using 20-minute intervals for batteries and photovoltaic inverters, and hourly intervals for OLTCs.
Through this model, Dr Raheel was able to reduce energy losses by a staggering 24,1% and improve load balancing by 25%, compared to the current fixed topology system. The model could be used for day-ahead scheduling, making it a promising solution for optimizing power distribution.
