A Two-Level Clustering Strategy For Energy Performance Evaluation Of University Buildings, Kehua Li, Zhenjun Ma, Duane A. Robinson, Jun Ma
A Two-Level Clustering Strategy For Energy Performance Evaluation Of University Buildings, Kehua Li, Zhenjun Ma, Duane A. Robinson, Jun Ma
Faculty of Engineering and Information Sciences - Papers: Part B
This paper presents a clustering strategy to evaluate the energy performance and identify typical daily load profiles of buildings. The cluster analysis included intra-building clustering and inter-building clustering. The intra-building clustering used Gaussian mixture model clustering to identify the typical daily load profiles of each individual building. The inter-building clustering used hierarchical clustering to further identify the typical daily load profiles of a stock of buildings based on the typical daily load profiles identified for each individual building. The performance of this strategy was tested and evaluated using the two-year hourly electricity consumption data collected from 40 buildings on a …

The increasing trend of connecting local distributed generation units to the grid has unlocked new economic opportunities for owners. This is supported by the ongoing development of energy storage technologies, especially battery based systems. In practice, battery storage systems typically operate based on control algorithms where tariff structures and future generation and load profiles are not taken into account. This paper investigates the results of a case study for a microgrid using a proposed optimization model which minimizes cost by considering an import/export tariff structure. The effect of changing time resolution related to variations in demand and generation is examined, …

In the last few years, the application of Model Predictive Control (MPC) for energy management in buildings has received significant attention from the research community. MPC is becoming more and more viable because of the increase in computational power of building automation systems and the availability of a significant amount of monitored building data. MPC has found successful implementation in building thermal regulation, fully exploiting the potential of building thermal mass. Moreover, MPC has been positively applied to active energy storage systems, as well as to the optimal management of on-site renewable energy sources. MPC also opens up several opportunities …
Performance Evaluation Of Full-Duplex Energy Harvesting Relaying Networks Using Pdc Self-Interference Cancellation, Jiaman Li, Le Chung Tran, Farzad Safaei
Performance Evaluation Of Full-Duplex Energy Harvesting Relaying Networks Using Pdc Self-Interference Cancellation, Jiaman Li, Le Chung Tran, Farzad Safaei
Faculty of Engineering and Information Sciences - Papers: Part B
In this paper, throughput and bit error performance of an in-band full duplex (IBFD) relaying system assisted by the radio frequency energy harvesting technique and the polarization-enabled digital self-interference cancellation (PDC) scheme are investigated. In particular, the relay node harvests power from the wireless radio frequency signal transmitted from the source node and uses this power to amplify and forward signals to the destination. Meanwhile, the PDC scheme is used at the relay node to cancel the self-interference signal in order to facilitate the concurrent in-band transmission and reception. The impact of both energy harvesting and self-interference cancellation on the …
