Abstract

Complex water networks, which have been structurally organized into Regional Supply and Urban Delivery networks from a functional perspective, are facing more challenges in their real-time control because of the reduced water resources, intensive energy requirements and increased attention towards the environmental impact of water use. Optimal management of complex water networks involves more difficulties because of different dynamics and control requirements in the specific parts. This chapter proposes a multi-layer model predictive control (MPC) with temporal multi-level coordination for regional supply and urban delivery networks. Inside each network, an MPC based controller is used. Between the regional supply and urban delivery networks, a temporal multi-level coordination mechanism is used to generate control strategies which consider objectives and time scales in different networks. According to the real practices, regional supply network works in a daily scale in order to achieve the global management policies for the different reservoirs, while the urban delivery network works in a hourly scale and is in charge of manipulating the actuators (pumps and valves) set-point to satisfy the local objectives. Real-life pilot demonstration in Catalunya (Spain) will be used to prove the general applicability of the proposed solution and its effectiveness for improving efficiency of water use, energy consumption and reducing computing load for complex water systems.
