A new multilayer controllable colored Petri net model applying to unit commitment problem

摘要

We present a new multilayer controllable colored Petri net (MCCP) architecture applied in unit commitment (UC) problem, which comprises three layers: physical, communication and supervisory layer. Each layer contains one or more sub controllable colored Petri nets (CCPs). Physical layer represents transition of states in a generation unit, which is helpful to solve the complex constraints in UC. Supervisory layer is designed for the purpose to evaluate different possible control policies, to choose the optimal one and then to get the final optimal generation schedule. Communication layer, a construction between physical and communication layers, is programmed to help physical layer and supervisory layer to communicate with each other. After modeling and analyzing, we find that this new MCCP not only can help us clearly program the algorithm without making trivial calculation errors, but also improve the calculation efficiency to a certain extend.
