Microgrids – the building block of a smart grid
The deployment of Smart Grid (SG) implies major changes in the operation and planning of distribution systems, particularly in the Low Voltage (LV) networks. The majority of small scale Distributed Energy Resources (DER) – Electric Vehicles (EV), microgeneration, storage units and flexible loads – are connected to LV networks, requiring local control solutions to mitigate technical problems resulting from its integration. Simultaneously, LV DER can be aggregated in small cells in order to globally provide new functionalities to system operators. Microgrids enable the optimal integration of consumers and the grid through the integration of variable renewable energy resources with dynamic demand strategies from demand response and electric vehicle recharging services, while reducing peak demand and stabilizing the electricity system. The coordination of MG local resources, through an appropriated network of controllers and communication system, endows the LV system with sufficient autonomy to operate interconnected to the upstream network or autonomously – emergency operation. Autonomous operation became a matter of utmost interest since in this way an increase on the resilience of the electric grid can be obtained, allowing self-healing following disturbances on the grid and capacity to feed consumers following natural disasters.
