    Design Considerations for Campus Micro-Grid: MCAST Case Study
    (Institute of Electrical and Electronics Engineers Inc., 2018-06) Azzopardi, Brian; Azzopardi, Stefan; Mikalauskienė, Renata; Salem, Al Agtash; Hadjidemetriou, Lenos; Tzovaras, Dimitrios K.; Borg, Nicholas Paul; Camilleri, Tim
    This paper aims to propose design considerations to transform the Malta College of Arts, Science and Technology (MCAST) current and future planned electrical network system into an efficient micro-grid. MCAST is a young higher education and research institution with its campus developing to a state-ofthe-art campus with a vision to establish a living laboratory for training and research. During this study, consumption of electrical loads and photovoltaic (PV) generation have been monitored in real-time to define the micro-grid concept. These measurements provide the values to integrate a combined 63kWp PV system together with intelligent loads such as heating, ventilation and airconditioning systems, and lighting, highlighting the integration capabilities. In addition, the future enlargement of the MCAST micro-grid is considered and recommendations are given on the infrastructure to complete an integral campus wide transformation. Eventually the 3DMgrid would be a blueprint for future micro-grids for training and research purposes. © 2019 Elsevier B.V., All rights reserved.

    A Hybrid Agent-Based Secondary Control for Microgrids With Increased Fault-Tolerance Needs
    (Institution of Engineering and Technology, 2018) Bintoudi, Angelina D.; Zyglakis, Lampros; Apostolos, C. Tsolakis; Ioannidis, Dimosthenis K.; Al-Agtash, Salem Y.; Martinez-Ramos, J. L.; Martensen, Nis; Tzovaras, Dimitrios; Tsolakis, Apostolos C.
    This paper proposes a hybrid secondary control architecture for microgrids with AC-coupled droop-controlled units, based on both centralised and distributed control principles. The proposed secondary control is based on a multi-agent system (MAS), complemented by a microgrid centralised controller (MGCC). The system is able to adjust the droop curves dynamically in order to achieve voltage/frequency restoration as well as active/reactive power optimal allocation, based on the actual status of the controllable units, in particular, the state-of-charge of batteries and maximum power point of photovoltaics. The distributed nature of the agents is also fully exploited because the proposed framework retains operability even under fault on secondary MGCC. To evaluate the proposed framework, a scenario-based performance analysis has been tested over a simulated AC islanded microgrid, where communication from the MGCC is suddenly interrupted and the MAS is required to reconfigure in order to maintain the same control objectives. MATLAB/Simulink simulations have been realised using detailed physical form models for a small-scale microgrid, while the implementation of the MGCC and MAS is accomplished through Java Agent Development (JADE) framework. © 2021 Elsevier B.V., All rights reserved.
