Short-term PVery Short-term Photovoltaic Power Forecasting Based on Cloud Tracking
The integration of PV power brings great economic and environmental benefits. However, the high penetration of PV power may challenge the planning and operation of the existing power system owing to the intermittence and randomicity of PV power generation. Achieving accurate forecasting for PV power generation is important for providing high quality electric energy for end-consumers and for enhancing the reliability of power system operation. Motivated by recent advancements in deep learning methods and their satisfactory performance in the energy sector, a hybrid deep learning model combining wavelet packet decomposition (WPD) and long short-term memory (LSTM) networks is proposed in this study. The hybrid deep learning model is utilized for one-hour-ahead PV power forecasting with five-minute intervals. WPD is first used to decompose the original PV power series into sub-series. Next, four independent LSTM networks are developed for these sub-series. Finally, the results predicted by each LSTM network are reconstructed and a linear weighting method is employed to obtain the final forecasting results. The performance of the proposed method is demonstrated with a case study using an actual dataset collected from Alice Springs, Australia. Comparisons with individual LSTM, recurrent neural network (RNN), gated recurrent (GRU), and multi-layer perceptron (MLP) models are also presented. The values of three performance evaluation indicators, MBE, MAPE, and RMSE, show that the proposed hybrid deep learning model exhibits superior performance in both forecasting accuracy and stability.
Machine Learning Based Adaptive Fault Prediction Data Analytics System for Lift Monitoring
Facility managers usually conduct reactive maintenance or preventive maintenance strategies in building maintenance management. However, there are some limitations that reactive maintenance cannot prevent failure, and preventive maintenance cannot predict the future condition of MEP components and repair in advance to extend the lifetime of facilities. Therefore, this study aims to apply a predictive maintenance strategy with advanced technologies to overcome these limitations. Building information modeling (BIM) and Internet of Things (IoT) have the potential to improve the efficiency of facility maintenance management (FMM). Despite the significant efforts that have been made to apply BIM and IoT to the architecture, engineering, construction, and facility management (AEC/FM) industry, BIM and IoT integration for FMM is still at an initial stage. In order to provide a better maintenance strategy for building facilities, a data-driven predictive maintenance planning framework based on BIM and IoT technologies for FMM was developed, consisting of an information layer and an application layer. Data collection and data integration among the BIM models, FM system, and IoT network are undertaken in the information layer, while the application layer contains four modules to achieve predictive maintenance, namely: (1) condition monitoring and fault alarming module, (2) condition assessment module, (3) condition prediction module, and (4) maintenance planning module. Machine learning algorithms, ANN and SVM, are used to predict the future condition of MEP components. Furthermore, the developed framework was applied in an illustrative example to validate the feasibility of the approach. The results show that the constantly updated data obtained from the information layer together with the machine learning algorithms in the application layer can efficiently predict the future condition of MEP components for maintenance planning.
The project aims to adopt latest research results in artificial intelligence (AI), data science (DS) and robotic technologies to create an environment where human beings can interact naturally with their electronic appliances such as coffee machines, washing machines and multimedia players etc. as similar to interact with another human.
High Fidelity Solar Irradiance Forecasting for Solar Power Integration
Solar energy is an abundant and renewable alternative to fossil fuels with essential implication of carbon neutrality. If utilized efficiently, it has the potential to supply the energy demand of the entire globe. However, there are two major obstacles that hinder the rapid deployment of solar power systems: (1) high temporal and spatial variability of solar irradiance that would cause instability and failure of power girds; and (2) low power production density per unit land area that would cause land competitions with existing infrastructures. To achieve the net-zero emission goal by 2050 set by several countries, innovate designs for solar power systems are essential to overcome the abovementioned obstacles. Large-scale energy storage (e.g. batteries) could stabilize fluctuate solar power to the grid, but grid wide battery systems are still not economically viable. A low-cost alternative to decrease the uncertainty in the solar power output is forecasting the solar power production to help with real-time dispatch and grid balancing. Accurate forecasting will also benefit the real-time control of the storage system.

Cyber-Physical Asset Management System
There is an increasing trend to adopt indoor location asset tracking in enterprises to enable better supply chain visibility and more efficient operations. In the past, Radio Frequency IDentification technology (RFID), Bluetooth Low Energy (BLE) and Wifi are commonly used in indoor positioning systems. Recently, Ultra-wideband (UWB) is considered as the new ideal solution for asset management for complex environments. Comparing to other similar technologies, UWB performs better in different aspects including accuracy, cost efficiency, reliability, scalability and safety. In the future research direction, the UWB-based Cyber-Physical Asset Management System can locate and monitor the factory assets, equipment, workers and products in real time. It can also progressively conduct workflow and resources utilization analysis, and carry out predictive maintenance so as to optimize the operations and minimize the cost as well as the energy consumption
Intelligent workload balance control of the assembly process considering condition-based maintenancee
A fuzzy control system is developed to make real-time decisions to balance the workloads based on the processing abilities of workstations, given the policy of condition-based maintenance. Fuzzy controllers are used to decide whether to re-balance the assembly line and how to adjust the production rate of each workstation. It is showed that the buffer level of the assembly line with our fuzzy control system is lower than that of the assembly line without any control system and the buffer level of the assembly line with another control system is the lowest. The intelligent automation can improve the performance of the assembly process by the fuzzy control system since real-time information of the assembly line can be used for adaptive decision-making
