Abstract: At present, microgrid scheduling mainly adopts static scheduling model, which ignores the dynamic characteristics of
micro gas turbine even when the scheduling time scale is very short. Based on the islanded microgrid, an intraday rolling dynamic
scheduling method of the islanded microgrid was proposed under the framework of model predictive control method, and the
dynamic characteristics of the micro gas turbine were considered under the condition of very short scheduling time scale.
Simulation results verified the effectiveness of the proposed intraday rolling dynamic scheduling method. Compared with the static
scheduling strategy, the dynamic scheduling strategy takes into account the dynamic characteristics of the micro gas turbine in the
scheduling model, and can combine more operation information to develop a more reasonable and effective scheduling scheme,
which can effectively reduce the deviation between the actual output power of the micro gas turbine and its output power set, and
better meet the load demand.
