Abstract

This paper tackles the complexities of benefit allocation among diverse stakeholders and layered uncertainties in collaborative operations, by proposing a dynamic pricing based bilevel distributionally robust scheduling approach for enhanced control over energy in multi-microgrid active distribution networks. At the outset, it addresses the challenge of equitable benefit allocation between active distribution network and multiple microgrids through a dynamic pricing mechanism sensitive to branch losses and energy-load distribution patterns. A structured bilevel model emerges, where the active distribution network determines transaction prices for microgrids through this pricing mechanism, while microgrids respond by adjusting their load schedules according to their demand requirements. Moreover, the influence of main grid price fluctuations and renewable energy production variability is encapsulated within a resilient bilevel distributed model. Through the application of mathematical deduction and duality theory, the original problem is reformulated into a mixed-integer second-order bi-level cone bilevel model, solved iteratively using a bisection method combined with the GUROBI solver. The practical efficacy of the proposed framework is demonstrated through the adaptation of the modified IEEE 33-node system.
