    by Karl Schnelle and Peter Rony

    Welcome to the 14th online issue of CAST Communications. In this issue, we are publishing three articles based on recent AIChE Annual meeting presentations given at the CAST Division Plenary sessions. Also included in this issue are a variety of communications on election results, awards, and the annual banquet.

    CAST Communications performs an important service to our Division members by publishing some of these presentations. Only 10% of our members attend the Annual Meeting; therefore, the Editors believe this publication is an important service to those CAST members who can not attend the talks in person. If you would like to see this service continue or to expand, please let us know [peter or kschnelle]. Having our CAST Division speakers submit their presentations for publication is an important benefit to the entire CAST Division membership. Therefore, it should be a specific responsibility for the area chairman to request that the best presentations be sent to CAST Communications.

    We, as editors of CAST Communications, have many colleagues to thank for the completion of this Winter 2010-2011 issue. We thank Gautam Kumar, Donald Chmielewski, and Sebastian Terrazas-Moreno for their articles, which are based on their presentations given at CAST Plenary Sessions at the 2009 and 2010 Annual Meetings of AIChE. The first presentation, by Gautam Kumar, was given in 2009 in Nashville, while the other two were given in 2010 in Salt Lake City. We thank our 2010 Computing-in-Chemical-Engineering winner, Nick Sahinidis, for sharing his award paper and presentation with the entire CAST division membership. We also thank Martha Grover and Matt Basset for their photos at the CAST banquet.

    In summary, the editors thank all contributors to this newsletter. [COPYRIGHT NOTICE: Contributions to this newsletter are copyrighted ©2011 in the name of the respective authors. All article rights are reserved by the authors or their respective organizations.] Peter Rony would also like to thank Karl Schnelle for his magnificent job at creating this issue of CAST Communications.

    Finally, a significant achievement has just been accomplished! All old issues of CAST Communications from the beginnings of CAST have been scanned into PDF format and loaded into our online archive!

    Broadcast Model Predictive Control of Multi-Cellular Systems
    by Gautam Kumar and Mayuresh V Kothare

    In multi-cellular biological systems, the behavior of skeletal muscle cells and control of these vast numbers of cells through few available actuators are important and challenging problems. Key mechanisms through which a few selected cells activate from vast number of cells to produce the aggregate desired response is still an open question in cellular biology. Besides this, smooth functioning of muscle cells with partial available information to the central nervous system and control architecture for this integrated system is not known completely. To understand this integrated system, one of the approaches among various possibilities is to apply engineering tools in order to develop theoretical models and control architectures. Several models and control architectures have been reported in the literature amongst which the idea of modeling these vast numbers of cells by taking a probabilistic approach and designing a control architecture based on broadcast feedback (Ueda et.al. [1, 2, 3, 4]) appears to be promising. Inspired by this idea, we have developed a probabilistic model for this multi-cellular system and control architecture using broadcast model predictive control. To the best of our knowledge, the idea of integrating broadcast feedback with model predictive control for this multi-cellular integrated system has never been introduced before.

    This presentation introduces this new idea of integrating broadcast feedback with model predictive control applicable to various systems similar to multi-cellular integrated system. We develop a non-homogeneous Markov model to represent multi-cellular systems with the known fact from literature that muscle fibers show only “ON” (excited) and “OFF” (relaxed) states. We consider that muscle cells are identical and behave independently. Based on this assumption, we define a pair of transition probability for switching states of cells and show the existence of such transition probabilities for an ensemble of cells by assigning the same transition probabilities to all cells within the system. These transition probabilities are function of system error defined as the difference of the desired number of “ON” cells and number of “ON” cells at a particular time instant. We further show the stability of this multi-cellular system rigorously using super-martingale theory [5] and robustness against permanently dead cells within the system when the information about number of dead cells is not available to the controller.

    The idea of broadcasting the same information to all the cells present in a multi-cellular system based on model predictive control is partly inspired by the functioning of our central nervous system. Whether the central nervous system makes decisions in a predictive sense is still unclear in the literature but intuitively it appears that our central nervous system may function as model predictive controller. Based on this, we design a model predictive control framework to compute transition probabilities which are then broadcast to all the cells within the multi-cellular system. We derive an expectation based model for the multi-cellular system in a predictive sense. Due to the dependence of transition probabilities on the system error, this model is non-linear. We consider a quadratic cost objective function and optimize it over the predefined prediction horizon with respect to transition probabilities. For this, we implement a strategy based on the sign of the system error. If the system error is positive then we restrict all the transitions from “ON” to “OFF” by setting transition probabilities of “ON” to “OFF” to zero over the prediction horizon. Similarly we put the restriction on transition of “OFF” to “ON” whenever the system error is negative. With this strategy we compute all pairs of transition probabilities over the prediction horizon. Out of all computed transition probabilities, we broadcast the first pair of transition probabilities to the multi-cellular system for the next sample time calculation. We obtain analytical expressions for transition probabilities for one step and two step predictors. Higher order predictor transition probabilities are obtained by solving non-linear coupled algebraic equations numerically. Further we design an observer for obtaining information such as time varying number of “ON” and “OFF” dead cells present within the multi-cellular system for better control strategy. Finally, the overall integrated multi-cellular system including observer is simulated in MatLab and future enhancement are proposed.

    Design of Massive Energy Storage Systems for IGCC Based Electric Power Generation
    by Donald J. Chmielewski, Benjamin P. Omell and Ming-Wei Yang

    The Integrated Gasification Combined Cycle (IGCC) possesses a number of benefits over traditional power generation plants, ranging from increased energy conversion efficiency to flex-fuel and carbon capture opportunities. Unfortunately, the large capital cost associated with an IGCC plant seems to outweigh its efficiency gain, as evidenced by the low interest in IGCC plant construction within the United States. A less known benefit of the IGCC configuration is the ability to load track electricity market demands. The idea being that the hydrogen product of the gasification unit can be stored during periods of low power demand. Then as demand increases along with the value of electric power, the stored hydrogen can be converted in combustion turbines. Exploitation of this load tracking feature will certainly increase profit margins and may push the IGCC process into economic viability. The objective of the current project is to size the hydrogen / energy storage unit as well as the set of combustion turbines used for hydrogen conversion.

    The effort begins with the design of a high level (supervisory) control system that is capable of market responsiveness. That is, design a controller that uses the electricity spot price as a disturbance input to the decision making process. However, in contrast to traditional controller designs, where the objective is to attenuate disturbances, the Market Responsive Controller should judiciously amplify the spot price disturbance. We have found that a Linear Quadratic Gaussian controller can be forced to have such behavior if the cross-term weights of the objective function are utilized. However, it is a non-trivial task to select weights such that profit is maximized (by producing electricity when the price is high and storing when low), while observing the equipment limitations of the storage and conversion units. Thus, a core result of the paper is the development of a profit maximizing scheme for the selection of LQG weights subject to process equipment limitations. The resulting optimization problem will be shown to be convex and thus will yield a globally optimal solution.

    Now turn to the question of sizing the storage and conversion equipment. Intuition suggests the following: Larger storage capacity coupled with larger conversion throughput will enhance the ability of the previous control scheme to exploit price swings. However, at some point the capital cost associated with ever larger equipment will begin to outweigh the increase in operating profit, resulting in a sign change in the levelized profit. Thus, the main result of the paper is the development of a levelized profit maximization scheme for the sizing of storage and conversion equipment. The resulting optimization problem is shown possess a linear objective function and convex constraints along with a small number of scalar reverse-convex constraints. Based on this formulation it will be shown that the optimization problem will yield a globally optimal solution with the aid of a branch and bound algorithm.

    A Decomposition Algorithm for the Optimal Design of Integrated Sites under Uncertainty
    by Sebastian Terrazas-Moreno, Ignacio E. Grossmann (Carnegie Mellon University), John M. Wassick, and Scott J. Bury (The Dow Chemical Company)

    An integrated site is a process network where several manufacturing plants producing different chemicals, final products and intermediates, are closely coupled (Wassick, 2009; Terrazas-Moreno et al., 2010). The objective of this work is to design an integrated site with maximum “effective production capacity”, given a capital investment constraint. A set of failure modes can occur at random times, and with random durations, in any of the plants in the network, decreasing its production capacity. To maximize the effective production capacity (minimize the effect of failures) a superstructure of the integrated site is postulated that includes parallel production units and intermediate storage tanks. The production capacity of the plants is also a degree of freedom, allowing excess capacity for building up inventories in the storage tanks.

    This problem can be modeled as a two-stage mixed-integer stochastic programming problem with endogenous uncertainties. The design variables of the integrated site are first-stage decisions, while the second-stage decisions involve operational variables such as internal flows within the integrated site, and the rates of accumulation or depletion of storage tank levels.

    Since the number of scenarios grows exponentially in the number of failure modes, the solution to large-scale instances of the problem becomes intractable. To overcome this challenge we propose a decomposition technique based on a novel implementation of Benders decomposition. The master problem includes the design variables and the operational variables of some of the scenarios with highest probability. The sub-problem includes the operational variables of the rest of the scenarios. The contribution of our method is that we solve the sub-problem in a reduced space that includes only the scenarios relevant to the flowsheet defined in the master problem. Furthermore, since the structure of the scenario tree in the sub-problem is known, we do not need to enforce non-anticipativity constraints

    The method was tested with the design of an industrial integrated site consisting of nine potential production plants and about one hundred possible failure modes. The Pareto-optimal curve for maximizing the effective production capacity and minimizing the capital investment was obtained using the e-constraint method. Reductions in computational time of up to an order of magnitude were obtained with the proposed Benders decomposition scheme when compared to the full-space solution of this example.
