“…Since the buildings such as commercial buildings or shopping malls contain coincidence of onsite cooling, heating, and electrical loads, CHP is suitable for the building supply. In research report [6], implementation of integrated model of cogeneration, solar, and conventional energy source is applied to energy demand in commercial building. The problem aims to minimize cost of life-cycle and earn profit from exporting onsite-generated electrical energy to grid based on national policy.…”

This paper presents optimal dispatch strategy of cogeneration with thermal energy storage (TES) for building energy management system (BEMS). In previous research related to cogeneration as a supply system, it is observed that there is some excessive heat from cogeneration operation released to the atmosphere. In order to improve energy efficiency, we therefore incorporate TES to utilize the excessive heat from cogeneration into two objective functions, i.e., total operating cost (TOC) and total carbon dioxide emission (TCOE). In particular, we aim to minimize TOC which is referred to economic optimal operation and to minimize TCOE which is referred to environmental optimal operation. Both optimal operations are subjected to energy dispatch strategy which TES constraint is taken into account. We demonstrate the dispatch strategy with a load profile of a large shopping mall as a test system and compare the results to that of previous dispatch of cogeneration without TES. The proposed strategy of cogeneration with TES can reduce TOC of the test system up to 4.15% and 1.85% for economic and environmental optimal operations, respectively. Furthermore, TCOE can be reduced up to 5.25% and 6.25% for economic and environmental optimal operations, respectively.

“…The devices with the GaSb/GaAs quantum dots (QDs) have been demonstrated to have some unique properties on different devices, such as widetuneable wavelength for light-emitting diode (LED), higher operation temperature for infrared photodetectors and long storage time for memory devices [3][4][5][6]. For this material system, the interface treatment between the QD and barrier layers is a critical issue due to the intense Sb-for-As exchange and Sb atom out-diffusion [7,8].…”

In this paper, GaSb nanostructures prepared under different Sb/background As ratios are investigated. With decreasing Sb/background As ratios, the morphologies of GaSb nanostructure changing from quantum dots (QDs) to quantum rings (QRs) are observed. The higher optical recombination probabilities of GaSb QRs are attributed to enhanced electron‐hole wave function overlapping and more surrounding electrons around the GaSb QR core shell. With well‐control Sb/background As ratios, the high‐temperature operation GaSb quantum‐dot infrared photodetector (QDIP) with simple stacked structure has been demonstrated.
