AC microgrid networking system suitable for offshore wind power consumption

Abstract

The invention discloses an AC microgrid networking system suitable for offshore wind power consumption. The AC microgrid networking system comprises an AC microgrid networking system body, at least one offshore wind farm, at least one high-capacity power converter, at least one boosting transformer, an AC bus I and a special wind power transmission line, wherein the AC microgrid networking systembody comprises at least two AC microgrid units and a system-level scheduling center; the offshore wind farm is connected with the boosting transformer through the high-capacity power converter; the boosting transformer is connected with the AC bus I; the AC bus I is connected with the special wind power transmission line; the special wind power transmission line is connected with the AC microgridunits of the AC microgrid networking system body; and the system-level scheduling center is connected with the AC microgrid units. According to the AC microgrid networking system suitable for the offshore wind power consumption, the problem that high-power wind power is difficult to consume and the problem of impact influence caused by large-scale network access of electric vehicles are solved.

Description

technical field [0001] The invention belongs to the technical field of micro-grids, and in particular relates to an AC micro-grid networking system suitable for offshore wind power consumption. Background technique [0002] In the process of exploring and developing clean energy that can replace petroleum, wind power is recognized globally as an effective solution that can effectively mitigate climate change, improve energy security, and promote low-carbon economic growth. of high attention. As far as China is concerned, in the "Guiding Opinions on Establishing a Guidance System for Renewable Energy Development and Utilization Targets" issued by the Energy Administration, it is clarified that the proportion of non-hydropower renewable energy in the electricity consumption of the whole society will reach 9% by 2020, and wind power will reach 9%. The proportion of consumption must reach more than 6%, and the proportion of coal-fired power generation enterprises to undertake n...
