What is it about?

A bi-level stochastic programming-based microgrid scheduling model is formulated. A hybrid analytic-heuristic solution algorithm, called Jaya-IPM, is developed.

Why is it important?

Demand response and uncertain renewable generations can be coordinated. The validity and superiority of the proposal are verified by a microgrid test system.

Perspectives

The test results show that the proposed method can coordinate the uncertainty of renewable generations with demand response strategies, thereby achieving a balance between the interests of microgrid and users; and that by leveraging demand response, the flexibility of the load side can be fully exploited to achieve peak load shaving while maintaining the balance of supply and demand. In addition, the Jaya-IPM algorithm is proven to be superior to the traditional hybrid intelligent algorithm (HIA) and the CPLEX solver in terms of optimization results and calculation efficiency. Compared with the HIA and CPLEX, the proposed method improves the MG net revenue by 10.9% and 11.9%, and reduces the user cost by 6.1% and 7.7%; our approach decreases the calculation time by about 90% and 60%.
