Flexible manufacturing workshop demand response scheduling method based on hierarchical game

Abstract

The invention relates to a flexible manufacturing workshop demand response scheduling method based on a hierarchical game, which belongs to the technical field of production scheduling, and comprises the following steps: firstly, constructing a flexible manufacturing workshop production scheduling management and control model based on time-of-use electricity price, and then aiming at the convergence and diversity problems of an algorithm on the basis of an NSGA-II algorithm, establishing a flexible manufacturing workshop production scheduling management and control model; introducing an opposite learning strategy and a self-adaptive crossover and mutation probability strategy; for the problem of machine load balancing, a machine load balancing strategy is adopted. According to the invention, flexible manufacturing workshop production scheduling based on time-of-use electricity price and demand response plays an important role in adjusting the load of a power grid and improving the load rate and operation stability of a power system; and the energy consumption cost of flexible manufacturing production is effectively reduced through production scheduling.

Description

technical field [0001] The invention relates to a demand response scheduling method for flexible manufacturing workshops based on layered games, and belongs to the technical field of production scheduling. Background technique [0002] In recent years, most research work on demand response has focused on residential and commercial users. However, currently 42.6% of global electricity consumption is caused by industrial production, so demand response from the industrial sector is particularly important to reduce peak demand on the grid. At present, most researches are focused on the continuous production process, and there is a lack of a general demand response model for discrete manufacturing. The main reason is that the complexity of the discrete model makes it difficult to establish a specific general mathematical model. [0003] Due to the flexibility of flexible manufacturing, consider flexible manufacturing workshops as industrial users to participate in the scheduling...
