Economic Optimization Scheduling of Distribution Networks - Microgrids Considering Power Interaction between Microgrids

In order to improve the economy of microgrid group operation and increase the scheduling space of microgrids, a two-stage optimal scheduling model considering the power interaction behavior among microgrids is established. In the first stage, the power purchase and sale tariffs from the distribution grid to the microgrid are simulated based on the forecast data; in the second stage, the microgrids are optimally dispatched based on the tariffs passed over in the first stage with the goal of maximizing the revenue of the microgrid cluster, and the optimal scheduling process takes into account the inter-microgrid power interaction behavior. The model is simulated and analyzed on MATLAB platform. The results show that the proposed model not only improves the revenue of the microgrid cluster, but also improves the robustness and independence of the microgrid cluster.
