NETWORKING METHOD FOR HIERARCHICAL CONTROL MICRO-GRIDS

摘要

A networking method for hierarchical control micro-grids is used for the development and utilization of renewable energy. The method includes: dividing a micro-grid into multiple multilevel micro-grids according to the distribution of distributed energy and loads (9), allowing or forbidding subordinate micro-grids (8) to transmit power to the bus (7) of current grid, and controlling the amount of the transmitted power. Each grid has an independent storage device (10) to ensure the stable power supply in current grid. The method can improve the security and stability of the power system during the grid-connecting of distributed energy.
