Energy Management Controller of a Resilient Micro-Grid for Critical Buildings

The continuous growth of electricity demand and ever increasing society awareness of climate change issues directly affect the development of the electrical power systems. The adaptation of Renewable Energy Systems (RES) offers reduction to the gas emissions produced by the electricity production from fossil-fuel power generation but also causes vulnerability to the power system. Recent technologies can be embraced to enhance the robustness of electricity supply in critical buildings. This paper proposes a method which uses an advanced control scheme for enhancing the operation of the critical building micro-grid during power-cut by utilizing the RES production. The method offers two different power management strategies (depending on the expected power system recovery time) for a resilient hospital micro-grid that includes RES; achieving longest autonomy of the micro-grid in island mode, or maximizing the load served within the micro-grid. The proposed method will be verified by simulation and selected results will be presented.2017 ESReDA copyright. https://www.esreda.org/ L. Hadjidemetriou, N. Flourentzou, E.
