409g Implementation of Coordinator Mpc on a Large-Scale Gas Plant
نویسنده
چکیده
In many cases economic optimal operation is the same as maximum plant throughput. This corresponds to maximum flow through the bottleneck(s). This insight may greatly simplify implementation and a real-time optimization (RTO) based on a nonlinear model is not necessary. The key issue is to identify the active "bottleneck" constraint and a coordinator MPC based on a linear model with constraints is proposed (Aske et.al., 2008)

Industrial Implementation of a Coordinator MPC for Maximizing Throughput at a Large-Scale Gas Plant
An industrial implementation of a coordinator MPC to maximize throughput at the large-scale K̊arstø gas plant is described. The “coordinator MPC” coordinates the flows through the network and not the local MPCs. It uses as degrees of freedom (MVs) the flows not used by the local MPCs (feeds, crossovers), and maximizes the throughput subject to the keeping the remaining capacities in all units ze...

In many cases economic optimal operation is the same as maximum plant throughput, which is the same as maximum flow through the bottleneck(s). This insight may greatly simplify implementation. In this paper, we consider the case where the bottlenecks may move, with parallel flows that give rise to multiple bottlenecks and with crossover flows as extra degrees of freedom. With the assumption tha...

متن کاملCoordinator MPC with focus on maximizing throughput
In cases where disturbances of economic importance have a dynamic character and if they occur frequently compared to the controlled plant responses, dynamic optimization is more suitable than traditional RTO. However, in many cases the optimal operation is the same as maximum plant throughput. To realize maximum throughput, the bottleneck(s) must be identified and maximum flow at the bottleneck...
متن کاملDesign and Practical Implementation of a New Markov Model Predictive Controller for Variable Communication Packet Loss in Network Control Systems
The current paper investigates the influence of packet losses in network control systems (NCS’s) using the model predictive control (MPC) strategy. The study focuses on two main network packet losses due to sensor to controller and controller to actuator along the communication paths. A new Markov-based method is employed to recursively estimate the probability of time delay in controller to ac...
