Day-ahead dispatch of multi-energy system considering operating conditions of multi-energy coupling equipment

A Comprehensive Review of the Design and Operation Optimization of Energy Hubs and Their Interaction with the Markets and External Networks

“…Different energy carrier conversion technologies are considered in the literature. Regarding heating and cooling carriers, the most considered technologies are CHPs [14,19,[21][22][23][24][25][26][27][28][29][30][31][32] and gas-fired boilers [14,[19][20][21][23][24][25]27,29,31,32]. As far as hydrogen technology is concerned, most papers consider hydrogen production through electrolysis [18,20].…”

“…For example, hydrogen produced by electrolysis can be used to produce methane via a methanation process, which can then be injected into the natural gas network [28]. Other thermal generation technologies considered are HPs [21,22,27,29,32] and chillers [21,26,29,32]. When it comes to the electricity carrier, both RES and conventional energy technologies may well be considered.…”

Multi-level coordinated energy management for energy hub in hybrid markets with distributionally robust scheduling

“…To deal with operation issues under demand uncertainties, [9] indicates that the energy management can be done more efficiently by a more precise day-ahead dispatch plan based on the probabilistic methods considering predictable information updates. Different from the single optimization in dayahead phase, some studies have also been conducted employing a two-stage probabilistic optimization framework to jointly optimize the day-ahead and real-time energy dispatches with different markets.…”

“…Since our work focuses on the coordinated energy bidding of EH in hybrid trading markets, and robust scheduling strategies hedging against worst-case uncertain distributions in different timescales, the multi-energy management model without considering nonlinear conversion features [11], [30] and startup shutdown costs [10], [31] can also be expressed. Interested readers can refer to [9] and [32] for more information about needed solution methods.…”

“…Note that the following input-output format can be extended to formulate nonlinear power-heat production relationship by including variable energy conversion ratios. However, due to nonlinear operating conditions[9], some piecewise linearization and non-convex model should be coped with, which will complicate problem formulations and may require some meta-heuristic optimization methods. This direction will not be elaborated on here.…”
