In this paper we investigate the possibility of soft-islanding (near-autonomous operation) a group of houses from the electric power grid in the Netherlands. Energy balancing is possible through applying multi-mode smart grid scheduling for controllable energy generation, storage and consumption devices. The modeled neighborhood consists of modern, well-insulated terraced houses in a typical Dutch...
In this work, we generalize our previous results concerning the impact of material recycling and energy recovery on plant dynamics and control. We define a generic class of integrated process systems, in which an extensive quantity that obeys conservation laws is recovered from the process output and recycled to the process feed; the operation of the system is assumed to be subject to time‐varying,...
Autothermal reactors, coupling endothermic and exothermic reactions in parallel channels, represent one of the most promising technologies for hydrogen production. Building our our prior results, the present work focuses on hydrogen generation in counter-current autothermal reactors. Using a first-principles model, we demonstrate that simply reversing the flow in a reactor designed for co-current...
In this paper, we analyze the energy dynamics of process networks comprising of a chemical reactor and a feed effluent heat exchanger (FEHE). Using singular perturbation analysis, we show that, in the case of tight energy integration, the energy dynamics of the network evolves over two time scales, with the enthalpy of individual units evolving in the fast time scale and the overall network enthalpy...
The present paper analyzes the energy dynamics of networked process units. In such systems, the material recycle streams interconnecting the units take on the additional role of energy carriers. In the presence of large energy input and output flows, the process networks considered are shown to exhibit a dynamic behavior with multiple time scales, with the variables in the energy balance evolving...
