Analysis of Power Transmission Line Loss Evaluation Model for Renewable Energy Sources

For the renewable energy source, the power supply load is affected by time due to the long line and many branches, and the power transmission line loss cannot be evaluated by the independent component loss method. The power transmission line loss evaluation model of the renewable energy source is studied. Define the renewable energy grid through the imbalance, determine the renewable energy grid range, pass the power line method based transmission line loss assessment method, the line equivalent resistance, line rms load current, line active power supply, line reactive power supply The average operating voltage of the quantity and line is used as the model input sample, and the power transmission line loss is used as the model output sample. After the input and output samples are standardized, the processed data is set by the kernel function to set the feature vector space, and the regenerative regression algorithm is used to establish the regenerative The energy transmission line loss assessment model of the energy source is used to implement the power transmission line loss assessment of the renewable energy source in the feature vector space. The experimental results show that the model evaluates the loss of power transmission line loss of renewable energy sources within 1%, and the adaptability is strong.
