As the energy landscape evolves, the integration of renewable energy resources (RES) and electric vehicles (EVs) presents both opportunities and challenges for power networks. A recent study led by Dharmesh Kumar from the Department of Electrical Engineering at Integral University Lucknow has introduced an innovative approach to frequency control in interconnected microgrid systems. Published in ‘Electrica’, the research highlights the potential of a fractional-order controller that could significantly enhance the stability and efficiency of modern power grids.
With the increasing penetration of RES, such as photovoltaic (PV) panels and wind turbines, traditional power systems are grappling with low inertia issues that can lead to unreliable frequency regulation. Kumar’s research addresses this pressing concern by employing a sophisticated control mechanism that combines tilt-integral-derivative with filter and hybrid fractional-order controllers. This unified approach not only manages disturbances effectively but also optimizes the frequency control in microgrid systems, which are increasingly reliant on renewable resources, energy storage units, and synchronous generators.
“The proposed controller demonstrates a remarkable ability to adapt to various disturbances, ensuring a stable and reliable grid operation,” Kumar stated. This capability is particularly crucial as the proliferation of EVs introduces additional complexities to grid dynamics. By leveraging the particle swarm optimization algorithm, the research fine-tunes controller settings, enhancing the overall performance of interconnected microgrid systems.
A case study conducted by the research team showcased the effectiveness of this fractional-order controller within a multi-area interconnected microgrid, integrating installed PV panels, wind turbines, and distributed EVs. The simulation results were telling; they underscored the superiority of the proposed controller over existing alternatives, marking a significant advancement in the field of energy management.
The implications of this research are profound for the energy sector. As the world transitions toward a greener future, efficient frequency control becomes paramount. This innovative controller not only promises to improve system dynamic performance but also paves the way for more resilient microgrid systems capable of accommodating the growing influx of renewable energy sources and electric vehicles.
As the energy industry grapples with the challenges posed by climate change and the need for sustainable solutions, Kumar’s research offers a glimpse into a future where interconnected microgrids can operate seamlessly, ensuring reliable power supply and enhancing grid stability.
