Research on Multi-objective Optimal Allocation of Multi-energy Carbon Reduction Devices in Regional Integrated Energy System
摘要
Abstract
In the face of the increasingly prominent energy crisis and global warming,building a low-carbon,clean,safe and efficient energy supply system is one of the important ways to improve environmental pollution and achieve the goal of"carbon peak,carbon neutrality".This paper proposes a multi-objective optimization model for the optimal allocation of multi-energy carbon reduction devices for integrated energy systems.Firstly,the carbon reduction characteristics of multi-energy carbon reduction devices are modeled,and the concept of system weighted average carbon potential is proposed.Using the proportion of branch carbon flow rate as the average carbon potential weight of each subsystem,the system's weighted average carbon potential overcomes the defect of unequal number and magnitude of load nodes among subsystems,and can reasonably characterize the overall carbon emission level of the system,avoiding the extreme situation of selecting only a single subsystem in the optimization process.Then,taking the lowest economic cost and the lowest weighted average carbon potential of the system as the objective function,a multi-objective optimal configuration model is established,and NSGA-Ⅱ algorithm is used to solve the construction scheme and cost of the optimal multi-energy carbon reduction device.Finally,a comprehensive energy system test example was used for verification.The example obtained the optimal configuration and cost of multi-energy carbon reduction devices under different carbon reduction effects according to the change of weighted average carbon potential,and the carbon reduction amount of each device and the total carbon reduction amount in the whole region,verifying the rationality of the proposed carbon reduction method.The verification results show that the concept of the system weighted average carbon potential proposed in this paper can be used as a carbon reduction sensitivity index to guide each energy subsystem to participate in the carbon reduction optimization process fairly and reasonably.关键词
