Abstract
Disclosed embodiments relate to a power monitoring system that may include an external power supply source, an energy storage system and a distribution board. In some embodiments, the power monitoring system includes the external power supply source, the distribution board, the energy storage system, a first power metering device, a second power metering device, a third power metering device and a server.
Claims13
A power monitoring system comprising:
- an external power supply source configured to apply power;
- a distribution board configured to distribute power applied from the external power supply source to a first load;
- an energy storage system (ESS) configured to store the power applied from the external power supply source and to discharge the stored power to the distribution board, wherein the ESS is further configured to operate in one of a charge mode, a mode in which AC current is passed (AC PASS mode), a charge and AC PASS mode, or a discharge mode, and wherein a second load is connected to the ESS for receiving power from the ESS;
- a first power metering device connected to an output of the external power supply source and configured to determine first power data applied from the external power supply source;
- a second power metering device connected to an input of the distribution board and configured to determine second power data distributed from the distribution board to the first load;
- a third power metering device connected to an input of the ESS and configured to determine third power data applied to the ESS;
- and
- a server configured to monitor power based on at least one of the first power data, the second power data, or the third power data when the ESS operates in one of the charge mode, the AC PASS mode, the charge and AC PASS mode, or the discharge mode,
- wherein, the power from the external power supply source is applied to the second load connected to the ESS via the distribution board and the ESS,
- wherein, if the ESS is being charged and the second load is consuming power, the server is configured to determine that an operational status of the ESS is the charge and AC PASS mode, using a power consumption pattern of the ESS and a power consumption pattern of the second load contained in one of the first power data or the third power data.
