Smarter Energy Recovery: How Fractional Order Controllers Are Changing the Game

"Unlock new levels of efficiency in renewable energy systems with fractional order proportional-integral (FOPI) controllers. Learn how this advanced technology is revolutionizing back-to-back power converters."


The relentless demand for electrical energy, coupled with growing environmental concerns, has spurred significant innovation in alternative and sustainable energy sources. Industries are increasingly exploring methods to recover energy from existing processes, turning potential waste into valuable resources.

One promising area lies in energy recovery from industrial pipelines, particularly those used in mining operations. These pipelines, which transport fluids over long distances and significant height differences, possess untapped energy potential. For example, studies of the Los Bronces - Las Tórtolas pipeline in Chile have revealed recoverable energy ranging from 22.03 kW to 34.35 kW.

This article delves into the application of fractional order controllers (FOCs) in energy recovery systems that use power converters. Moving beyond traditional PID controllers, we'll focus on the benefits of fractional order proportional-integral (FOPI) controllers in optimizing the performance of back-to-back (BTB) power converters. We'll explore how these advanced controllers can improve energy recovery from mining pipelines, offering a more efficient and adaptable solution compared to conventional methods.

Fractional Order Control: A New Era for Power Converters

Futuristic industrial landscape with glowing energy pipelines and a subtle grid overlay representing renewable energy innovation.

Fractional calculus and fractional control have emerged as dynamic fields of research, impacting various disciplines. Unlike traditional integer order controllers, fractional order controllers (FOCs) offer enhanced flexibility and precision in system control. This is particularly relevant for energy recovery systems, where fluctuating conditions and complex dynamics demand sophisticated control strategies.

The core of this advancement lies in the fractional order proportional-integral (FOPI) controller. To understand its significance, it's helpful to break down the key components:

  • Fractional Order Integration: Traditional integration is extended to non-integer orders, allowing for finer adjustments and responsiveness in control systems.
  • Flexibility and Tuning: FOPI controllers offer more tuning parameters than standard PI controllers, providing greater control over system behavior.
  • Adaptability: FOPI controllers can better handle non-linearities and uncertainties in the system, making them ideal for fluctuating energy sources.
The diagram of the machine side controller (MSC) shows the traditional PI controllers replaced by FOPI controllers. The grid side controller (GSC) control strategy is based on the coordinate transformation abc-dq. FOPI controllers guarantee a rapid transient response and a high static performance. The results obtained were similar to those of more complex controllers.

The Future is Fractional: Embracing Advanced Control for Sustainable Energy

The adoption of fractional order control schemes represents a significant step forward in optimizing energy recovery from sources like industrial pipelines. By utilizing FOPI controllers in back-to-back power converters, we can achieve greater efficiency and stability compared to traditional methods.

The enhanced performance of FOPI controllers stems from their additional degrees of freedom, allowing for finer adjustments and better adaptation to fluctuating energy sources. This translates to improved energy recovery and a more reliable integration of renewable sources into the grid.

As the demand for sustainable energy solutions continues to grow, fractional order control is poised to play a crucial role in maximizing the potential of renewable energy systems. Further research and development in this area will undoubtedly pave the way for even more innovative and efficient energy recovery technologies.
