Abstract:

To address the problems of multi-media iron and steel energy planning model with more variables, complex constraints and high difficulty in model solving, an improved MOEA/D (decomposition-based multi-objective evolutionary algorithm) based on adaptive neighborhood is proposed to realize multi-media energy planning optimization. Considering the characteristics of TOU price and the buffer effect of gas holder, the objective function to minimize operation cost and total energy consumption is constructed. And the model constraints are designed such as energy supply and demand balance. The decoding method based on energy production and consumption rules is designed to determine the target value. The normalized Chebyshev aggregation function and the adaptive neighborhood update of population evolution degree are used to improve the design of MOEA/D energy planning optimization algorithm. Through simulation and comparison experiments, it is verified that the improved MOEA/D can effectively realize energy planning optimization and improve the convergence of the solution. The optimized scheme reduces the operation cost by 1.3% and energy consumption by 1.2%.
