High-Quality Development Method of Distribution Networks Considering the Characteristics of “Source-Grid-Load-Storage”

Considering the characteristics of “one low, two peaks, three high and multiple random factors” of the new power system under the dual-carbon target, the morphological characteristics and framework of high-quality distribution network development are analyzed. By analyzing the composition and layered structure of the new distribution system and the influence of flexible resources on the distribution network, the impact of “source network load and storage” on the high-quality development of the distribution network is obtained. Combined with the basic tasks and advanced goals of the power distribution system, the countermeasures of the power grid company and the specific measures to deal with the safety of the power distribution network under the goal of “dual carbon” are formed. A robust two-stage optimal scheduling method for the virtual power plant has been developed to deal with the uncertainty of new energy generation and load demand. The experimental results prove the safe and stable operation of the distribution network.
