Robust design optimization of a photovoltaic-battery-heat pump system with thermal storage under aleatory and epistemic uncertainty Vrije Universiteit Brussel
Combining photovoltaic arrays with batteries, heat pumps and thermal storage further decarbonizes the heating sector. When evaluating the performance of such systems, the parameters are either fixed, or based on generic ranges, or characterized by precise distributions inferred from limited information. These assumptions result in suboptimal designs, for which the actual performance differs drastically from simulations. To address these ...
The Role of Electrofuels under Uncertainties for the Belgian Energy Transition Vrije Universiteit Brussel
Wind and solar energies present a time and space disparity that generally leads to a mismatch between the demand and the supply. To harvest their maximum potentials, one of the main challenges is the storage and transport of these energies. This challenge can be tackled by electrofuels, such as hydrogen, methane, and methanol. They offer three main advantages: compatibility with existing distribution networks or technologies of conversion, ...
Recuperator performance assessment in humidified micro gas turbine applications using experimental data extended with preliminary support vector regression model analysis Vrije Universiteit Brussel
Cycle humidification applied to micro gas turbines (mGTs) offers a solution to overcome their limited operational flexibility in terms of variable electrical and thermal power production when used in a combined heat and power (CHP) application. Although the positive impact of this cycle humidification on the performance has already been proven numerically and experimentally, very detailed modeling of the system performance remains ...
Analysis of the dynamics of a slider-crank mechanism locally actuated with an act-and-wait controller Vrije Universiteit Brussel
An experimental and modeling study of ammonia with enriched oxygen content and ammonia/hydrogen laminar flame speed at elevated pressure and temperature Vrije Universiteit Brussel
Experimental investigation on ammonia combustion behavior in a spark-ignition engine by means of laminar and turbulent expanding flames Vrije Universiteit Brussel
Control strategy development for optimized operational flexibility from humidified micro gas turbine Vrije Universiteit Brussel
Waste heat recovery through cycle humidification is considered as an effective tool to increase the operational flexibility of micro Gas Turbines (mGTs) in cogeneration in a Decentralized Energy System (DES) context. Indeed, during periods with low heat demand, the excess thermal power can be reintroduced in the cycle under the form of heated water/steam, leading to improved electrical performance. The micro Humid Air Turbine (mHAT) has been ...
Robust design optimization and stochastic performance analysis of a grid-connected photovoltaic system with battery storage and hydrogen storage Vrije Universiteit Brussel
Balancing of intermittent energy such as solar energy can be achieved by batteries and hydrogen-based storage. However, combining these systems received limited attention in a grid-connected framework and its design optimization is often performed assuming fixed parameters. Hence, such optimization induces designs highly sensitive to real-world uncertainties, resulting in a drastic mismatch between simulated and actual performances. To fill ...
