The LIINES seeks Quantitatively-Minded Dartmouth Undergrad for Smart Grid Research Competition

The LIINES seeks 1-2 quantitatively-minded Dartmouth undergrads for participation in a smart grid research competition.  This work is a direct extension of our prior work in the smart power grid research theme.   The competition involves multi-agent system negotiation techniques as applied to power system operations and management.  The work can serve as part of a senior thesis or an undergraduate research opportunity.
The successful student(s) will be driven by a sincere interest in the smart grid field and have an affinity to object-oriented programming.   Engineering science or computing science majors are preferred although preparations in heavily computational disciplines such as physics, applied mathematics, and economics are welcome.  A prior portfolio in an object-oriented programming language is required.  C++ is specifically preferred.   More senior undergraduate students are preferred although initiative, interest, and programming fluency will be the determining criteria.

Interested students may contact Prof. Amro M. Farid for further information and an interview.

The LIINES is moving to Dartmouth

After four years at the Masdar Institute of Science and Technology, the Laboratory for Intelligent Integrated Networks of Engineering Systems is moving to the Thayer School of Engineering at Dartmouth!  The move comes as Amro M. Farid assumes his new appointment as an Associate Professor of Engineering at the Thayer School.
As one of the prestigious Ivy League universities, Dartmouth is consistently ranked amongst America’s top dozen universities.  Moreover, the Thayer School of Engineering has several features that when taken together make a well-customized home for the LIINES.   It:
As the LIINES makes its move to Dartmouth, its important to reflect upon some of its achievements in the last four years.  From its initial focus on smart power grids, it’s research program has expanded to address the application of control, automation and information technology to intelligent energy systems.  This has meant the development of three additional research themes namely:
These efforts have lead to several notable outputs.  In research publications, these include 17 journal papers since January 2014 with an average impact factor of 3.874, 2 books, 4 book chapters and 43 conference papers.  In teaching, two new courses were developed ESM 501 System Architecture and ESM 616 Techno-Economic Analysis in Power System Operations.  We are happy that students at the Masdar Institute consistently rated both of these courses highly.  The LIINES has also increasingly taken on an international profile with active leadership in the IEEE Control Systems Society (CSS) Technical Committee on Smart Grids, the IEEE Systems, Man & Cybernetics (SMC) Society Technical Committee on Intelligent Industrial Systems, and the Council of Engineering System Universities (CESUN).
Of course, the LIINES’s productivity is largely due to its students.  And so this is also a moment to recognize their hard work and dedication.  This began with the 2013 cohort  Apoorva Santhosh, Reshma Francy, Reem Al Junaibi, Aramazd Muzhikyan continued to William Lubega in 2014 and more recently Deema Allan, Wester Schoonenberg, and Halima Abdulla.  Thanks to the support of Prof. Kamal Youcef-Toumi, their MIT student colleagues Hussein Abdelhalim, Fang-Yu Liu, and Bo Jiang have also been instrumental in fostering a collaborative international atmosphere despite the time zone hurdles.  Each of these students has made strong research contributions to the growth of the lab and have gone on to successful careers beyond graduation.
Going forward, the LIINES will continue to work in the intelligent energy systems area as part of the Thayer School’s commitment to energy and complex systems.   That said, the LIINES members at Masdar will remain as such and will continue their research in the spirit of international collaboration as their MIT student colleagues have done in the past.  Dr. Toufic Mezher, Professor of Engineering Systems & Management has kindly agreed to coordinate the LIINES student members as they complete their degrees.   Naturally, we will also continue to  collaboration with the MIT Mechanical Engineering Department and more specifically Prof. Kamal Youcef-Toumi, the Mechatronics Research Laboratory and the Center for Clean Water & Energy.
We’re looking forward to an exciting new 2015-16 academic year at the LIINES.  Stay tuned for more!

Journal Paper Accepted at the Journal of Intelligent Manufacturing: Measures of reconfigurability and its key characteristics in intelligent manufacturing systems

The LIINES is pleased to announce that the Journal of Intelligent Manufacturing has accepted our paper entitled: “Measures of reconfigurability and its key characteristics in intelligent manufacturing systems”. The paper is authored by Amro M. Farid and was published in October 2014.

Many manufacturing challenges arise with the global trend of increased competition in the marketplace.  Production processes must deal with shorter product lifecycles and mass-customization. Consequently, production systems need to be quickly and incrementally adjusted to meet the ever-changing products. Reconfigurable manufacturing systems have been proposed as a solution that facilitates changing production processes for highly automated production facilities.

Much research has been done in the field of reconfigurable manufacturing systems. Topics include: modular machine tools and material handlers, distributed automation, artificially intelligent paradigms, and holonic manufacturing systems.  While these technological advances have demonstrated robust operation and been qualitatively successful in achieving reconfigurability, there has been comparatively little attention devoted to quantitative design methodologies of these reconfigurable manufacturing systems and their ultimate industrial adoption remains limited.

Measuring reconfigurability of manufacturing systems quantitatively has been a major challenge in the past, since a quantitative reconfigurability measurement process was non-existent. Earlier work developed a measurement method that extracts measurables from the production shop floor. When this was established, basic measures of reconfiguration potential and reconfiguration ease were developed, based on axiomatic design for large flexible engineering systems and the design structure matrix respectively.

Reconfiguration of a production process can be split up in four steps: Decide which configuration, Decouple, Reorganize, and Recouple. The larger the number of elements in the system, the more configurations are made possible. This is measured using the reconfiguration potential measure, based on axiomatic design for large flexible engineering systems.

Production processes contain multiple interfaces within themselves. Multiple layers of control can be distinguished, that have to work together to coordinate the physical components. These interfaces are the main determinants for the reconfiguration ease measure.

This paper combines these techniques to define a quantitative measure for reconfigurability and its key characteristics of integrability, convertibility and customization.    The intention behind this research contribution is that it may be integrated in the future into quantitative design methodologies for reconfigurable manufacturing systems, which may be easily adopted by industrial automation and production companies.

About the author: Wester Schoonenberg completed his B.Sc. in Systems Engineering and Policy Analysis Management at Delft University of Technology in 2014. After his bachelors’ degree, Wester started his M.Sc. at Masdar Institute of Science & Technology. Currently, Wester is working on the integrated operation of electrical grids and production systems with a special interest in the demand side management of industrial facilities.

Journal Paper Accepted at IEEE Transactions on Industrial Electronics: An Enterprise Control Assessment Method for Variable Energy Resource Induced Power System Imbalances. Part 2: : Parametric Sensitivity Analysis

We are happy to announce that our recent paper entitled: “An Enterprise Control Assessment Method for Variable Energy Resource Induced Power System Imbalances. Part 2: Parametric Sensitivity Analysis”, has been accepted to IEEE Transaction on Industrial Electronics. The paper is authored by Aramazd Muzhikyan, Prof. Amro M. Farid and Prof. Youcef Kamal-Toumi.

The variable and uncertain nature of the variable energy resources (VER) introduces new challenges to the balancing operations, contributing to the power system imbalances. To assess the impact of VER integration on power system operations, similar statistical methods have been used by renewable energy integration studies. The calculations are based on either the net load variability or the forecast error, and use the experience of power system operations. However, variability and forecast error are two distinguishing factors of VER and both should be taken into consideration when making assessments.

This paper uses the methodology from the prequel to systematically study the VER impact on power system load following, ramping and regulation reserve requirements. While often ignored, the available ramping reserve reflects the generation flexibility and is particularly important in the presence of VER variability. This provides a detailed insight into the mechanisms by which the need for additional reserves emerges. The concept of enterprise control allows studying the impact of power system temporal parameters as well as net load variability and forecast error holistically.

The application of an enterprise control assessment framework allows the empirical identification of the most influential parameters different types of resource requirements. The inclusion of the power system temporal parameters, such as day-ahead market (SCUC) and real-time market (SCED) time steps, is a particularly distinguishing feature of the work. Use of the case-independent methodology allows generalization of the results and prediction of how the system resource requirements change when one of the parameters varies. Moreover, the results reveal the degree of importance of each lever for the power system reliable operations which is crucial for the strategic planning of the grid modernization.

Duke Energy on Analytics and the Internet of Things

It’s been a long time since 2003 when the concept of the Internet of Things was first proposed by U. of Cambridge Auto-ID Laboratory.  At the time, Dr. Amro M. Farid, now head of the Laboratory for Intelligent Integrated Networks of Engineering Systems, was a doctoral student investigating how RFID technology enabled intelligent products within reconfigurable manufacturing systems.  The Internet of Things was being applied primarily in the manufacturing and supply chain domain.

Since then, the Internet of Things concept has taken hold not just in manufacturing systems and supply chains but nearly every industrial system domain including energy.    Every “thing” or “device” has the potential to be connected via an intelligent sensor so as to make decisions — be they centralized within an operations control center — or distributed amongst artificially intelligent multi-agent systems.   The Internet of Things concept has the potential to fundamentally transform industrial systems.

Have a look at Duke Energy’s take on the Internet of Things:

The LIINES is proud to have been working in this area since its inception and continue to do so.  More information on our research can be found on the LIINES website.

Engineering systems as the continued evolution of engineering to real world problems

In a recent blog post entitled:  “Systems Engineering is just plain old Engineering — not more and certainly not less“, the author questions and discusses systems engineering, engineering systems as part of engineering.

Deeper insight is gained by looking at the definition of engineering itself.  One good definition of engineering is:  “Engineering is the professional art of applying science to the optimum conversion of the resources of nature to benefit man.”  In the same book, we find: “Engineering is an art requiring the judgement necessary to adapt knowledge to practical purposes, the imagination to conceive original solutions to problems, and the ability to predict performance and cost of new devices or processes.”  (D. W. Oliver, T. P. Kelliher, and J. G. Keegan, Engineering complex systems with models and objects. New York: McGraw-Hill, 1997, pp. 25.)

The real question is whether engineering — as it stands today — does indeed meet these definitions.  Any discipline when analyzed traditionally is two things:  a core of methodological activities and a set of typical applications.   So the question becomes whether these methodological activities are sufficient for the applications; the practical problems that when solved would benefit man.

One challenge of modern engineering is its division into multiple disciplines.  Mechanical, electrical, civil and chemical are but a common few.  Each of these comes with their own core of methodologies and typical applications.   Therefore, it becomes increasingly difficult even within engineering itself to apply methodologies from one engineering discipline into another.  It is equally difficult to apply core methodologies in atypical applications.

Coming back to the definition of engineering, some practical problems are simply so big that they require methodological activities from multiple engineering disciplines and in of themselves are the union of multiple typical domains of application.  Here, it is important to recognize the common adage:  “The whole is greater than the sum of its parts“.

And so traditional systems engineering was born shortly after World War II.  Defense applications like jet fighters and satellites clearly draw from mechanical, electrical, and computer engineering.   Astronautical and Aeronautical engineering departments naturally recognize the need for cross-disciplinary activity and have often included the Systems Engineering Handbook within their curricula. Similar trends emerged in nuclear power plants and even highly automated production facilities.

The four research themes at the Laboratory for Intelligent Integrated Networks of Engineering Systems are further examples of this continuing trend.  The energy-water nexus draws heavily from electric power engineering and water resources management.  The electrification of transportation draws heavily from transportation engineering, electric power engineering, and the mechanical engineering of cars and trains.  Smart (power) grids — as cyber-physical systems — recognize that electric power engineering must expand to include new developments from control systems, optimization, signal processing, communications and information technology.  Similarly, reconfigurable manufacturing systems are cyber-physical and integrate similar subjects.

While integrating knowledge from multiple engineering disciplines is helpful, it is insufficient to meet the original definition of engineering as above.  What if the engineering application requires natural resources that are deemed too large by society?  Till today, people ask this of the Big Dig project in Boston.  Another question.  Does the engineering application truly benefit mankind?  We ask this today in the context of nuclear disarmament.  These questions draw heavily from economics, management, political science and ethics.  And they are relatively subjective as compared to the typical methodological activities found in the engineering disciplines.  And yet, it is naive to think that their solution does not require engaged participation of engineers and their disciplines.

These types of questions dominate 21st century problems as compared to those of the 20th century.  In the 20th century, traditional engineering disciplines began from a set of requirements and ended with some product or service as a solution.  These requirements represented the economics, regulations, policies and ethics as an operating box for engineers.   This role, however, is changing.  In the 21st century, engineers no longer take these “requirements” as given but instead have an expanding role of influence. Chief technology officers have increasingly important roles in the innovative success of modern companies.  Government regulators often seek engineers within their ranks.  And many nations are finding engineers within their legislative and executive branches of government.  We’ve moved from a decomposed top-down world to one that is innovative and bottom-up.

It is from this lens that the field of engineering systems finds itself.  It’s still the same engineering definition but the nature of the problem has changed.  This is a good sign.  Engineers are increasingly bringing pervasive solutions to benefit mankind.  As they do, they will increasingly interface with the disciplines devoted to people and society:  the humanities and social sciences.  As that happens, adhering to the definition of engineering will require engineers to converse with these disciplines.  Common definitions and methods are likely to develop as all of these disciplines collectively work to solve mankind’s techno-economic-social problems.
