Reasonable calculation of network usage charge is an important prerequisite for promoting the development of distributed energy nearby trading. The existing methods for calculating network usage charge are challenging to balance the needs of grid companies to recover transmission and distribution asset investment and the operational needs to guide distributed energy nearby trading in smoothing the net load curve. The paper proposes a two-stage dynamic network usage charge measurement method based on right-and-responsibility-matching principle: first, a right-and-responsibility-matching static network usage charge measurement method is proposed to ensure the fair and reasonable recovery of network construction costs; then, a time-sharing dynamic adjustment method for network usage charge is proposed to motivate the users of distributed energy nearby trading to smooth the net load curve peak-to-valley difference through price signals. On this basis, a bilevel optimization model is established, with a dynamic adjustment model of network usage charge in the upper level and a distributed energy nearby trading model in the lower level, and the value of the dynamic network usage charge is measured by solving the model. Finally, simulation results show that the proposed method for calculating dynamic network usage charge can effectively ensure the reasonable recovery of transmission and distribution asset investments for grid companies while significantly reducing the peak-to-valley difference rate of the net load curve.
