Taking the annual net energy import volume and annual cost as targets, a two-layer collaborative optimization method considering both system optimal configuration and operation strategy is used. The novel system will be used to supply energy to a nearly zero-energy community.
The two-layer collaborative optimization method is suitable for the collaborative optimization design of complex energy systems with HES and multiple renewable energy utilization technologies. The thermodynamic performance and comprehensive benefits analysis method in this paper are also applicable to other energy systems.
This analysis supplements prior studies and evaluates the extent to which diverse types of emerging long-duration energy storage (LDES) and multi-day energy storage (MDS) technologies could serve as DEFRs and help New York achieve a reliable, affordable, zero-carbon grid.
A two-layer multiple scenario stochastic optimization framework is developed. The improved kernel density estimation is used for probability density estimation. A novel strategy to actively adjust of energy contribution ratio is proposed. The performance of proposed strategy is superior to those of traditional strategies.
New York needs 4.8 GW of multi-day storage by 2030 and 35 GW by 2040 to reliably integrate renewables and achieve decarbonization goals. This study identified a 4.8 GW need for multi-day energy storage in the least-cost 2030 portfolio, which grows to 35 GW by 2040.
The integrated energy system (IES), coupled with renewable and conventional energy, has been recognized as a promising solution to achieve a low-carbon energy supply for buildings due to its high energy efficiency and excellent sustainable performance [ 2 ].
In other engineering areas, a multi-scenario mixed-integer linear program was proposed to solve chemical supply chains with uncertainty, and the two-stage problem was converted to two scenarios [11]. A multi-scenario and multi-objective optimization model was proposed for the operation control of the CO 2 flooding pipeline network system [12].
Therefore, the optimal value of η ERDC has a half drop from Scenario 1 (0.671) to the rivals (Scenario 2: 0.321, Scenario 3: 0.303). 5 Conclusions In this study, an engineering target-oriented multi-scenario retrofit methodology for the optimization of HENs was proposed from the viewpoint of exergoeconomic assessment.

Unfortunately, the performance of existing multi-scenario recommendation approaches is poor since they introduce unnecessary information from other scenarios to target scenario. In this paper, we show it is possible to selectively utilize the information from different scenarios to construct the scenario-aware estimators in a unified model.
