Abstract
The disclosure is related to a method for estimating an operation state of each individual load in a target electric power consumer. The method may include obtaining an operation state table of a target electric power consumer upon generation of a predetermined event, collecting predetermined electricity parameter values in response to a request to estimate an operation state of each individual load, and estimating operation states of individual loads in the target electric power consumer based on the obtained operation state table and the collected predetermined electricity parameter values.
Claims15
A method of managing and distributing electricity, the method comprising:
- receiving an initiation input to generate an estimated operation state of each individual load in a target electric power consumer;
- obtaining an operation state table of the target electric power consumer in response to the generated event, wherein the operation state table includes information on all combinations of operation states of each of the individual load in the target electric power consumer mapped with corresponding electricity parameter values;
- wherein the operation states of individual loads is mapped with first electricity parameter values, wherein the first electricity parameter values are measured from a meter of the target electric power consumer when the individual loads in the target electric power consumer respectively have the operation states mapped to the first electricity parameter values;
- initiating the estimate of the operation state of each individual load in the target electric power consumer by measuring and collecting predetermined electric parameter values from a single measuring source;
- wherein the operation state includes an On-state and an Off-state and an electricity parameter value includes at least one of a voltage, a current, an alternating current frequency, a power factor, an active power, a reactive power, an apparent electric power, and a harmonic wave;
- wherein a predetermined electric parameter value denotes a sum of the electricity parameter value collected from all individual loads considering each individual loads condition of on and off state;
- comparing the measured and collected predetermined electric parameters with the obtained operation state table;
- and
- managing the target electric power consumer based on the estimated operation states of the individual loads in the target electric power consumer to distribute the electricity.
