Research on the double-layer intra-day management and control method of ring structure microgrid cluster based on multi-time scale

In general, a tree-like or radial connection structure is adopted by the microgrid cluster (MGC) to connect to the power grid. However, the power interaction is restricted by the bus capacity, and the management and control are complicated in the tree-like or radial connection structure. Therefore,...

Therefore, the ring structure MGC is proposed to solve the above problems. Intra-day rolling correction method based on the ring structure MGC at different time levels is investigated in this paper.
