-
(Elsevier, 2019-02)A multi-objective optimization model is developed for a multi-microgrid system, which not only minimizes its operational cost but also the emissions. The performance of the proposed model is evaluated by comparing its ...
-
(Elsevier, 2019-02)The increased penetration of renewables has prompted the integration of battery energy storage systems (BESSs) in active distribution networks. The BESS not only act as backup power supply but also provides various ancillary ...
-
(Elsevier, 2019-02)On-load tap changer (OLTC) plays a significant role to regulate the voltage of the power system. Although some time, secondary voltage of an OLTC is pulled down when tappings are raised to restore the voltage level. This ...
-
(Hindawi, 2019-10-13)hybrid energy system is investigated. It incorporates the appliance time scheduling with appliance-specific power dispatch. The optimization is aimed at minimizing energy cost, maximizing renewable energy penetration, and ...
-
(Springer, 2019-01)An improved topology with a fault ride through (FRT) capability when subjected to a DC-link fault-based wind power plant (WPP) employing a Vienna active rectifier-I is proposed in this paper. The proposed system is capable ...
-
(International Federation of Automatic Control, 2019)The control goals for a froth flotation cell are to maintain a stable pulp level and maximise the separation between valuable minerals to the concentrate and gangue to the tailings. Only a limited set of manipulated variables ...
-
(International Federation of Automatic Control, 2019)The inverse relationship between grade and recovery in flotation circuits is well accepted, and forms the basis of control strategies used to maxisise recovery subject to grade specifications. The concept of peak air ...
-
(International Federation of Automatic Control, 2019)This paper proposes a method to measure and reject disturbances caused by changes in the ore distribution of the feed to a grinding mill circuit. A computer vision system is presented to measure the fraction of rocks in ...
-
(MDPI Publishing, 2019-08-05)This work aims to measure the thermodynamics of a main cabin ventilation system in a JU-2000E jack-up offshore platform. A three-dimensional (3D) physical model of the ventilation system was established, and the computational ...
-
(Hindawi Publishing, 2019-01)Sensing is a fundamental aspect in cognitive radio networks and one of the most complex issues. In the design of sensing strategies, a number of tradeoffs arise between throughput, interference to primary users, and ...
-
(MDPI, 2019-02)In practice, maritime monitoring systems rely on manual work to identify the authenticities, risks, behaviours and importance of moving objects, which cannot be obtained directly through sensors, especially from marine ...
-
(Wiley, 2020-03)Cognitive radio networks have achieved higher efficiency in terms of spectrum usage; however they do not readily solve any competition for access among secondary users. Optimisation is applied to an underlay network to ...
-
(Institute of Electrical and Electronics Engineers, 2020-01-16)Internet of Things (IoT) deployments are on the rise globally with Low Power Wide Area Networks (LPWAN) providing the wireless networks needed for this expansion. One of these technologies namely Long Range Wide Area ...
-
(Elsevier, 2020-04)A Hybrid Nonlinear Model Predictive Control (HNMPC) strategy is developed for temperature control and power consumption minimisation of a cooling water network. The HNMPC uses a gradient descent optimisation algorithm for ...
-
(Wiley, 2020-05)We present, experimental broadband propagation characterization of a planar groove gap waveguide (PGGWG) from 29 to 40 GHz. The transmission line Q‐factor is found to vary from 110 to 130 over the band, which is shown by ...
-
(Energy Research Centre, University of Cape Town, 2019-11)The optimised placement of reclosers on a distribution network is known to improve the reliability of a power system. Furthermore, the protection settings on distribution systems rely heavily on the number and placement ...
-
(Institute of Electrical and Electronics Engineers, 2019)Traction power systems are susceptible to service affecting electrical faults or disturbances. These may cause interruptions of the power supply to the trains, affecting systems operations and causing major delays. ...
-
(Elsevier, 2020-02)The selection of an appropriate descriptive system and modeling framework to capture system dynamics and support process control applications is a fundamental problem in the operation of industrial processes. In this study, ...
-
(Elsevier, 2020-03)Existing studies have shown the benefits of battery energy storage systems (BESS) inclusion, but do not consider optimal BESS sizing and operation in a peer-to-peer (P2P) energy sharing network under different BESS ownership ...
-
(Wiley, 2020-04)Some low power wide area network (LPWAN) developers such as Sigfox, Weightless, and Nwave, have recently commenced the integration of cognitive radio (CR) techniques in their respective LPWAN technologies, generally termed ...
