Method and Practice of Multi-objective and Real-time Optimal Control in Urban Drainage System

由于极端天气和城市化进程的影响,传统的排水系统运行模式在解决城市内涝、合流制溢流等问题时面临严峻挑战。随着人们对水环境和水安全的日益关注,在安全、生态、效益等方面对城市排水系统运行提出了更高要求。城市排水系统多目标实时优化控制通过对控制仿真模型、多目标管理体系、优化算法等技术的研究,可实现设计优化方案、构建优化系统、制定与分析优化策略等功能,为源-网-厂-河一体化运行提供技术支持。介绍了城市排水系统中多目标实时优化控制的具体方法及其在某市的应用效果,并提出实时控制技术应用中面临的新挑战。

Due to the influence of extreme weather and urbanization process,the traditional operation mode of urban drainage system(UDS) is encountering severe challenges in addressing urban flooding and combined sewer overflow issues.As greater emphasis is placed on water environment and water safety,elevated standards are being set for the operation of UDS with a focus on safety,ecology,and overall benefits.By delving into control-oriented model,multi-objective management system,optimization algorithm and other technologies,it becomes possible to design optimization schemes,establish optimization systems,and determine and analyze optimization strategies for the multi-objective and realtime optimal control in USD.This approach can offer technical support for the integrated operation of UDS including wastewater source,wastewater pipeline network,wastewater treatment plant,and river.This paper introduces the specific method of multi-objective real-time optimization control in UDS,and its application effect in a certain city.The new challenges faced in the application of real-time control(RTC) technology are proposed.
