Consider the Way of Gathering Network Tariff for High Frequency Distributed Electricity Trading in Distribution Networks

With the introduction of the dual carbon target and the step-by-step measures to achieve these two targets, renewable energy generation resources are expanding rapidly, including not only large centralized wind and PV plants, but also a large number of distributed resources concentrated in the distribution grid. Based on the scenario of high-frequency trading of distributed resources in the distribution network, a reasonable charging model is needed to achieve cost recovery and to ensure the safety and reliability of distribution network operation. In this paper, through the comprehensive cost method and the distribution network over-grid fee collection method based on the line utilization rate, different collection methods are adopted at different development stages of different distribution networks, which can effectively recover the distribution network costs and guide the transaction behavior of users through the over-grid fee to ensure the stable operation of the distribution network.
