specific Embodiment

[0112] This embodiment adopts figure 2 The improved IEEE 33-node power distribution network topology is shown, in which nodes #1-13 and #19-28 form a microgrid①, nodes #14-18 form a microgrid②, and nodes #29-33 form a microgrid③ , the access of diesel engine, wind power, photovoltaic, energy storage power station and mobile energy storage at each node is as follows: figure 2 As shown, the access nodes of mobile energy storage in microgrid ①, microgrid ②, and microgrid ③ are node #28, node #18, and node #33, respectively. The emergency dispatch time period of the distribution network is set to be 4 hours, and the unit dispatch time is 10 minutes. The test scenario indicates that after a power outage accident occurs, the connection between the distribution network and the large power grid is interrupted, and the three microgrids that make up the distribution network enter the isolated grid operation state at the same time. In the embodiment, taking two mobile energy storage ...

Abstract

The invention discloses a power distribution network emergency scheduling settlement method and device considering mobile energy storage and a medium. The method comprises the following steps: constructing a power distribution network emergency scheduling energy model considering mobile energy storage resource participation; determining the shared energy and the microgrid new energy consumption rate of all participants in the scheduling time period according to the optimal energy scheduling scheme; based on the shared energy and the micro-grid new energy consumption rate, determining a bargaining factor of each participant by using a bilateral incentive mechanism; an asymmetric Nash bargaining model is applied to construct a power distribution network emergency scheduling settlement model considering mobile energy storage resource participation; and solving the power distribution network emergency scheduling settlement model by using an optimization solver to obtain an optimal settlement scheme of the power distribution network. Mobile energy storage can be effectively stimulated to participate in emergency scheduling of the power distribution network, and the flexibility, economy and reliability of emergency power supply of the power distribution network are effectively improved.

Description

technical field [0001] The invention relates to the technical field of power system operation and energy planning, in particular to a method, device and medium for emergency dispatch and settlement of a power distribution network that take into account mobile energy storage. Background technique [0002] Affected by the small probability and high risk extreme disaster accidents, the distribution network has the possibility of large-scale and long-term power outages, resulting in the breakdown of each microgrid in the distribution network and entering the isolated network operation state. In this isolated grid operation scenario, considering that the energy storage system and diesel engines in each microgrid have insufficient energy supply, only relying on the energy storage system and diesel engines cannot meet the power supply needs of all loads during the emergency dispatch period. . Therefore, it has become a research topic to design an integrated method of dispatching a...
