A hierarchical power control system associated with a cloud server includes a first microgrid cell, a second microgrid cell, a third microgrid cell, a middleware server, and an integrated control system. The first microgrid cell includes a first energy storage system (ESS) having an uninterruptible power supply (UPS) structure and a first load having a power state managed by the first energy storage system (ESS). The second microgrid cell includes a second load and a second energy storage system (ESS) for managing a power state of the second load. The third microgrid cell includes a third load. The middleware server communicates with the first to third microgrid cells. The integrated control system receives power supply-demand state information of the first to third microgrid cells through the middleware server, and establishes an integrated operation schedule based on the received power supply-demand state information of the first to third microgrid cells.

Hierarchical power control system

The present disclosure relates to a hierarchical type power control system. The hierarchical type power control system connected to a cloud server includes: a first microgrid cell including a first energy storage system (ESS) having an uninterruptible power supply (UPS) structure and a first load that a power state thereof is managed by the first ESS; a second microgrid cell including a second load and a second ESS managing a power state of the second load; a third microgrid cell including a third load; a middleware server communicating with the first to third microgrid servers; and an integrated control system communicating the middleware server and integrally controlling power supply states of the first to third microgrid cells, wherein the first microgrid cell and the second microgrid cell are connected to each other through a converter to interchange power therebetween.

Hierarchical type power control system

Optimal operation and scheduling based on microgrid demand states

The present invention relates to a micro-grid system including a load. The load includes: a distributed power source including one or more elements which generate power; and a controller configured to derive a first load pattern by measuring load data of the load when the load is added to the micro-grid system established in advance, compare the first load pattern with a preset load pattern for each load type, and operate the distributed power source based on a result of the comparison.
