6 FAQs about [Time scale of microgrid]

What is a multi-time scale scheduling strategy for Microgrid?

In , a multi-time scale scheduling strategy was proposed for microgrid, in which the system is able to pre-allocate the capacity of the system before the day and adjust the day-ahead scheduling plan according to the real-time capacity of renewable energy sources during the day.

What is the optimal scheduling strategy for microgrids?

In order to balance the accuracy, economy and robustness of microgrid scheduling better, a multi-time scale optimal scheduling strategy for microgrids considering the uncertainty of source and load is proposed.

How long does a microgrid multi-time scheduling optimization take?

As the last step of the entire microgrid multi-time scheduling optimization, the real-time adjustment stage takes 15 min as the control time domain and 5 min as the index value.

Why is multi-time scale optimization applied in microgrid dispatching?

The accuracy of the prediction value of source and load has the characteristic of improving with the decrease of the time scale, so multi-time scale optimization is applied to the field of microgrid dispatching to maintain the smooth power of contact lines between microgrid and external networks , , .
