| description | The invention provides a distributed power supply sensing method based on state estimation. The method comprises the following steps: establishing a distributed photovoltaic power supply database in a sensing area based on an SCADA (Supervisory Control and Data Acquisition) distribution system; extracting real-time data of a centralized grid-connected photovoltaic power supply in an SCADA platform database, calculating real-time output of a regional distributed power supply S, and drawing a sensing curve; and step 2, evaluating the obtained regional distributed photovoltaic real-time output value, comparing the integral electric quantity with the meter electric quantity data, if the error requirement is met, outputting a distributed photovoltaic output data sensing curve, and if the error requirement is not met, carrying out error correction, and carrying out the step 2 again until the error requirement is met. According to the distributed photovoltaic real-time output curve output by the method, the regional |
