Market-1ike Distributed Coordination of Individually Constrained and Coupled Production Plants with Quadratic Approximation

摘要

The optimal operation of large chemical or petrochemical production sites is challenging,because streams of shared resources such as steam or intermediates physically couple the individual production plants.For a feasible operation,it is essential to coordinate the production of the plants to balance the networks for the shared resources.Often,finding a central solution to this site-wide optimization problem is not possible due to various barriers such as the lack of models,too large complexity,or the management structure that hinders the exchange of relevant information.Market-1ike distributed optimization tackles some of these barriers,especially if only limited data exchange is possible between the constituent production plants.However,distributed optimization algorithms typically need many iterations,which hinders their practical application.In this contribution,we compare an algorithm for distributed market-1ike coordination that we formulated in previous work for individually constrained coupled systems with ADMM for a novel case study.
