Multiple-criteria evaluation of centralized chilled water hub powered by industrial waste heat and renewable energy

Multi-criteria dispatch optimization of a community energy network with desalination: Insights for trading off cost and security of supply

“…Within this framework, the comprehensive operational costs of the system and the quantity of water extracted from groundwater reservoirs are simultaneously optimized, yielding a collection of solutions that adhere to Pareto optimality. Furthermore, an integrated energy and cold water hub is proposed in [ 26 ], where the absorption chillers are driven by electricity generated from solar and biomass resources in normal operating conditions, and by fossil fuel-fired generators in shortages of renewable resources. Moreover, the most widely used technologies for seawater desalination, namely multi-effect desalination and reserve osmosis, are comparatively analyzed in [ 27 ] in the context of a community energy network given their different constraints in terms of continuous operation.…”

“… •No provisions are procured for measuring the security of supply. [ 26 ] •Deterministic optimization •Optimization-based TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) approach •Single-objective optimization •The thermal storage is optimally dispatched in an intelligent, look-ahead manner. •A centralized cold-water center is optimally operated, which integrates an electric chiller, a multi-effect absorption chiller, and absorption chillers for the use of different fuels.…”
