According to an embodiment, energy management system includes client and server. Server includes acquisition unit, estimation unit, calculator and controller. Acquisition unit acquires data concerning electrical equipment in a building including a storage battery from client. Estimation unit estimates energy demand and energy generation amount in building based on the data. Calculator calculates, based on the energy demand and the energy generation amount, operation schedule of the electrical equipment to optimize energy balance in building under a constraint that minimizes dump power to be discarded after storage battery is fully charged. Controller creates control information to control electrical equipment based on operation schedule.

Energy management system, server, energy management method, and storage medium

According to an embodiment, energy management system includes estimating module, preparing module and controller. Estimating module estimates energy demand of a home, and obtains estimated value of energy demand of home. Estimating module estimates energy generation amount and obtains estimated value of the generation amount. Preparing module prepares discharge strategy, based on the estimated energy demand and generation amount. Discharge strategy maximizes balance obtained by subtracting power purchase loss from power selling profit, by using a push-up effect. The controller controls discharge of the energy storage, based on actual values of the energy demand and the generation amount, and the discharge strategy.

Energy management system, energy management method, program, server apparatus, and local server

According to one embodiment, energy manager includes first estimator, second estimator, creator and controller. First estimator estimates power amount of power generator. Second estimator estimates energy demand. Creator creates schedule of devices based on estimated power amount and energy demand. Controller controls the devices based on the schedule. Second estimator includes storage, extractor and calculator. Storage accumulates load data. Extractor extracts load patterns including different load data. Calculator calculates weight for each of extracted patterns. Creator includes simulator and scheduler. Simulator simulates evaluated value of each schedule based on the pattern and weight. Scheduler creates schedule based on evaluated value.

Renewable energy management using weighted load patterns

A radar detection device of an example of the present invention includes a section which increments a value of a counter when a first difference value between a receiving power value in detecting an edge of a received signal of wireless communication and a receiving power value after a first time elapses since the edge detection is more than a first threshold, and a section which determines whether a second difference value between the value of the counter and a value of the counter before a third time is not lower than a second threshold in each of passage of a second time, and determines that radar is detected when the second difference value is not lower than the second threshold.

Radar detection device used in wireless communication device

A wireless communication equipment system which performs wireless communication among one master station and more than one slave station is configured so that each of the slave stations requests the master station to reply acknowledgement frames so as to perform transmission acknowledgement to broadcast frames or multicast frames transmitted from the master station. The master station is configured to decide order of replies of the acknowledgement frames of the slave stations which have requested the replies of the acknowledgement frames and to notify the order of the replies of the acknowledgement frames.

Wireless communication equipment system for wireless local area network communication, and wireless communication sequence for the system

When a communication is performed between an access point and a wireless terminal according to the IEEE 802.11 of a wireless LAN communication, a MAC layer block of a wireless communication apparatus used as the access point adds an identifier showing a support of aggregated transmission of a MAC layer management frame or upper layer several frames to a body of a beacon frame.

Wireless communication apparatus capable of performing aggregated transmission

An access point transmits data frames to a plurality of wireless terminals by MC or BC communication. When the data frames are transmitted, data to identify the presence of the return of an ACK frame as affirmative acknowledgment with respect to transmitted contents is applied to an MAC header. In a case where a Block ACK frame is requested as affirmative acknowledgment with respect to the transmission of a plurality of frames in the MC or BC communication, the plurality of wireless terminals return the Block ACK frame to the access point and the wireless terminals other than the wireless terminal itself by the MC or BC communication.
