Research And Design Of Energy Dynamic Balance And Optimal Schedule System In Iron And Steel Enterprise

Steel industry is high energy consumed. Energy management in iron and steel enterprise is of great significance dealing with energy dynamic balance, saving energy, and optimal utilization of energy. There are categories of energy in iron and steel company, forming complicated energy network. To solve the energy schedule problem, we model the energy system, make and optimize the energy scheduling plan from the whole view.Aiming at the problem of energy dynamic balance and optimal schedule, this thesis advanced a solution which represents the problem as a mathematical programming problem based on the mathematical model of the energy system. The solution is designed into a software system. We also depicted the software framework and detailed the design and implementation specifics here. The main contributions of this thesis are as follows:1. Classify energy related scheduling units in iron and steel plant, and model every class of unit uniformly. According to the relationship with energy, we classify all the scheduling units into four classes. Considering immeasurable factors, we introduced dummy variables. Accuracy estimation and parameter modification strategy are also available.2. Based on models of the energy network and scheduling units, represent the schedule problem as a mathematical programming problem in which client requirements appear in the form of target function and energy balance equations and all kinds of inequalities are considered as constraints.3. Solve the mathematical programming problem. By converting the target function, we converted the problem to a linear mathematical programming problem. We solve it with primal-dual interior-point method and introduced a dynamic optimizing strategy that can dealing with sudden abnormal outbursts.4. Design and implement the energy dynamic balance and optimal schedule software system. System framework, outbound interface, database, UI, performance, security, and operability were all paid sufficientattention. Inner representations of the system together with implement details are also depicted here.
