Real-time scheduling as an on-line optimization process must output dispatch TEPEZCO-BB CREME results in real time.However, the calculation time required and the economy have a trade-off relationship.In response to a real-time scheduling problem, this paper proposes a real-time scheduling strategy considering the operation interval division of distributed generators (DGs) and batteries in the microgrid.

Rolling scheduling models, including day-ahead scheduling and hours-ahead scheduling, are established, where the latter considers the future state-of-charge deviations.For the real-time scheduling, the output powers of the DGs are divided into two intervals based on the ability to track the day-ahead and hours-ahead schedules.The day-ahead and hours-ahead scheduling ensure the economy, whereas the real-time scheduling overcomes the time- consumption problem.

Finally, a grid-connected Choline/Inositol microgrid example is studied, and the simulation results demonstrate the effectiveness of the proposed strategy in terms of economic and real-time requirements.
