Accuracy Analysis and Verification of Demand Superposition Calculation Method Based on Power Curve

At present, some enterprises use the method of multi-circuit demand superposition to obtain the actual maximum demand for the two-part electricity price settlement. There are two main ways to realize the multi-circuit demand superposition. One is to use the communication means to superimpose the power information of the electric energy metering devices of each circuit in real time to obtain the actual maximum demand. Another method is to collect and superimpose the power curve data of the metering device remotely through the information system. This paper evaluates the uncertainty of the demand superposition calculation method based on different power curves, analyzes and evaluates the accuracy of its calculation, and compares and verifies it with actual case data. The results show that the calculation method of dispatching the power curve combining the second-level curve and the minute-level curve has both economy and accuracy, and has great practical application value.
