Energy storage system of apartment building, integrated power management system, and method of controlling the system
First Claim
1. An energy storage system of an apartment building,the energy storage system converting power generated by a renewable power generation system so as to supply the converted power to a grid, a load, or a common load or to store the converted power in a battery for each apartment in the apartment building, supplying power supplied from the grid to the load, converting the power supplied from the grid so as to store the converted power in the battery, and converting the power stored in the battery so as to supply the converted power to the grid, the load, or the common load, andthe energy storage system being connected to an integrated power management system of the apartment building via a network so as to transmit power consumption amount data for each apartment regarding a power amount supplied to the grid or the load, and to control a power supply amount to be supplied to the common load from each apartment based on control data of the integrated power management system by reducing the power supply amount from individual apartments to the common load for all apartments in the apartment building or the grid when the power consumption amount data for each apartment is greater than a calculated remaining power amount for each apartment.

1. An energy storage system of an apartment building,
the energy storage system converting power generated by a renewable power generation system so as to supply the converted power to a grid, a load, or a common load or to store the converted power in a battery for each apartment in the apartment building, supplying power supplied from the grid to the load, converting the power supplied from the grid so as to store the converted power in the battery, and converting the power stored in the battery so as to supply the converted power to the grid, the load, or the common load, and the energy storage system being connected to an integrated power management system of the apartment building via a network so as to transmit power consumption amount data for each apartment regarding a power amount supplied to the grid or the load, and to control a power supply amount to be supplied to the common load from each apartment based on control data of the integrated power management system by reducing the power supply amount from individual apartments to the common load for all apartments in the apartment building or the grid when the power consumption amount data for each apartment is greater than a calculated remaining power amount for each apartment.

7. An integrated power management system,
the integrated power management system being connected to an energy storage system of each of a plurality of apartments in an apartment building via a network, the integrated power management system receiving from the energy storage system power consumption amount data regarding a power amount supplied to a grid or a load of each apartment, calculating a remaining power amount of each apartment based on the received power consumption amount data, generating control data regarding a power supply amount to be supplied to a common load for all the plurality of apartments based on the calculated remaining power amount, and transmitting the generated control data to the energy storage system of each apartment reducing the power supply amount from individual apartments to the common load for all apartments of the plurality of apartments or grid when the power consumption amount of the individual apartment is greater than the calculated remaining power amount for said individual apartment.
-
13. A method of controlling an integrated power management system connected to an energy storage system of each of a plurality of apartments in an apartment building via a network, the method comprising:
-
receiving from the energy storage system power consumption amount data regarding power supplied to a grid or a load of each apartment; calculating a remaining power amount of each apartment based on the received power consumption amount data; generating control data regarding a power supply amount to be supplied to a common load based on the calculated remaining power amount; transmitting the generated control data to the energy storage system of each apartment; monitoring an actual power consumption amount of each apartment of the plurality of apartments at a time period; comparing the monitored actual power consumption amount and a calculated remaining power amount for each apartment of the plurality of apartments at the time period and creating a comparison result; and generating the control data regarding the power supply amount to be supplied to a common load for all the plurality of apartments from each apartment based on the comparison result, said control data reducing the power supply amount from individual apartments to the common load for all apartments when the monitored actual power consumption amount of the individual apartment is greater than the calculated remaining power amount for said individual apartment. - View Dependent Claims (14, 15, 16, 17, 18)
