Micro-grids are used to maximize the usage of local renewable energy sources while improving power quality and ensuring economic feasibility. Micro-grids can run either connected to an upstream grid or in stand-alone islanded mode. Here, the main challenge is the control of the single assets (generators and load) and of the power, which is exchanged with the grid as well as the transition between the two operation modes. This can be enabled with different control principles ranging from fully centralized to fully decentralized concepts.
In the currently running project 3DMicroGrid an “agent based” control scheme, where each asset is equipped with a primary control agent (instant reaction to frequency and voltage deviations) is developed. Additionally, a micro-grid central controller (MGCC) is responsible for secondary control (optimal power flow and adjusting of nominal voltage and frequency after deviations). In the case of a failure of the MGCC, the agents can fulfil primary and secondary control tasks by communicating with each other.
The goal of the project is not only the design and development of the smart micro-grid concept, but also the physical implementation of the micro-grid on the campus of the Malta College of Arts, Science and Technology (MCAST).
Energynautics contributes to the development and testing of the controller concept. Besides, the project largely benefits from Energynautics’ experience in developing microgrids, which was gained during the “Cell Controller” project.
Altogether, a consortium of 10 universities and companies from 8 countries work on the realization of the 3DMicrogrid project.
