The significance of microgrid day-ahead optimization

This manuscript proposes a hybrid method for optimizing day-ahead Microgrid (MG) scheduling, incorporating EV and energy sources. The proposed hybrid method is the joint execution of the Sunflower optimization algorithm (SFO) and Contrastive Self-Supervised Graph Neural Network (CSGNN).

The integration of renewable energy resources into the smart grids improves the system resilience, provide sustainable demand-generation balance, and produces clean electricity with minimal .

In the day-ahead scheduling stage, a two-stage distributionally robust optimal scheduling model is established with the objective of minimizing the comprehensive day-ahead scheduling cost of the microgrid, and the optimal day-ahead scheduling solution is found under the probability distribution of the worst scenario.

Day-ahead scheduling and optimization algorithms are essential for effectively planning microgrid operations, ensuring the efficient use of energy resources. These processes involve forecasting energy demand and generation for the upcoming day, allowing microgrids to prepare and allocate resources accordingly [ 68 ].

The presented paper introduces an efficient strategy for energy management and minimize the daily operating cost of a grid-connected MG based on two levels: optimal day-ahead scheduling based on.
