摘要

作为提高城市垃圾处理利用率和综合能源供给效率的有效手段，垃圾能源供给与城市多能源系统协同运行模式需要深入研究。然而，现有的运行优化理论忽略了废物能源供应、储能系统和城市能源系统之间的相互作用，这将难以实现废物能源供应和可再生能源利用的最大化。本文提出了一个包含废弃物资源化利用系统（UWRUS）和多能源存储系统（MESS）的城市多能源系统框架。首先，根据废物产量、最大废物存储量与相应的能源供应特性之间的关系，建立了UWRUS模型；在此基础上，提出了一种混沌模型，以提高多能系统的运行灵活性。在此基础上，建立了基于废弃物资源化和多储能协同的城市多能系统优化模型。最后，通过仿真对比分析对所提方法进行了验证。实例研究的结果和经验表明，所提出的协调模型可以提高能源效率和运行经济性。与现有方法相比，能源利用效率提高7.8%，总运行成本降低18.4%。

Optimal operation of urban multi-energy system via coordination of waste resourceful utilization and multi-energy storage

As promising means to improve urban waste disposal utilization and the comprehensive energy supply efficiency, the coordinated operation mode of waste energy supply and urban multi-energy system needs to make a profound study. However, the existing operation optimization theory ignores the interaction between waste energy supply, energy storage system and urban energy system, which will make it difficult to maximize waste energy supply and renewable energy utilization. In this study, an urban multi-energy system framework with waste resourceful utilization system (UWRUS) and multi-energy storage system (MESS) is proposed. Firstly, an UWRUS model is established by the relationship between the waste output, the maximum waste stockpile and the corresponding energy supply characteristics. Then, a MESS model is proposed to improve the multi-energy system operation flexibility. On this basis, an urban multi energy system optimal model based on waste resourceful and multi-energy storage collaborative is established. Finally, the proposed method is tested and verified by simulation comparison analysis. The results and experiences of the case studies show that the proposed coordinated model can improve the energy efficiency and operation economy. The energy utilization efficiency is 7.8 % more and total operation cost is 18.4 % less compared with existing methods.
