6 FAQs about [Microgrid off-grid shutdown steps]

How do I transition from on-grid to off-grid mode?

3.4.2. Transition from on-grid to off-grid mode The on-grid to off-grid operation transition of a microgrid can be performed following a contingency (Emergency Islanding) or by a planned operation. In this case, the EMS must be capable to manage the microgrid in order to ensure a seamless islanding transition.

How to resynchronize a microgrid to the main grid?

Two different control loops have been implemented to resynchronize the microgrid to the main grid. The first one is based on an active method which forces the master unit to adjust its active and reactive power outputs to rapidly adapt the overall system frequency and voltage magnitude to the reference signal.

Should a microgrid be operated in off-grid mode?

If technical or economic reasons suggest operating the microgrid in off-grid mode, a planned islanding can be considered as in the case of the NTUA, the Hydro Quebec and the BC hydro master-slave controlled microgrids.

How does a microgrid work?

All these components are connected to a common AC busbar that is in turn connected to the main grid through a circuit breaker which can be opened in order to isolate the microgrid. This device is also equipped with a Synchrocheck Relay enabling the microgrid to be reconnected to the main grid, if adequate conditions occur.

How to prevent microgrid instability?

The voltage and frequency stability during the system operation in the off-grid mode constitutes another difficult task to deal with. To mitigate the risk of microgrid instability, the electric energy balance needs to be ensured in the on-line environment.
