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

A monitoring apparatus in an electric power system includes a communication unit for performing communication with a data server included in the electric power system to receive real-time data, a user input unit for receiving user input for creating a monitoring screen with the real-time data by using a tabular function, and a display unit for displaying the monitoring screen. The apparatus further includes a control unit for creating the monitoring screen in response to the user input to display it in the display unit, to decide at least one or more tasks taking time more than a given time in processing them among a plurality of tasks for performing the tabular function, and to process the at least one or more task and the other remaining tasks than the at least one or more task among the plurality of tasks simultaneously in parallel.

Monitoring apparatus in electric power system

Disclosed embodiments relate to data management apparatuses and methods of an energy management system. In some embodiments, the data management apparatus includes: a control unit configured to process data collected from a power system; and a real-time database composed of the processed data. The control unit may receive an input for entry selection for data inquiry on the real-time database irrespective of a hierarchy of a data entry and inquire data from the real-time database based on the received input.

Energy management system

Disclosed embodiments relate to a synchronizing method of a client device in an energy management system. In some embodiments, the method includes: deciding a synchronization object server for downloading synchronization data; downloading the synchronization data from the decided synchronization object server; determining whether or not the status of operation of the client device is synchronizable, based on the downloaded synchronization data; and performing a synchronization operation for the downloaded synchronization data based on a result of the determination.

Apparatus and method for data synchronizing of energy management system

Disclosed herein is a method of controlling data display device. The method includes: loading a monitoring view to initialize it; determining whether to display a tabular view; setting a tabular module if it is determined that the tabular view is to be displayed; displaying the tabular view according to set conditions; and checking whether to perform a view update mode during the displaying the tabular view.

Method of  controlling data display device

Embodiments of a display apparatus of an energy management system are presented. The display apparatus may include: a first screen updating unit including a drawing unit configured to determine a screen to be output based on a screen operation input and update data and an object included in the determined screen to configure an output-scheduled screen and a first temporary storage unit configured to store the configured output-scheduled screen; and a second screen updating unit configured to receive the stored output-scheduled screen and output the received output-scheduled screen through a screen output unit.

Apparatus and method for displaying in energy management system
