Influencing Factors and Construction Principles of Topology Selection for Large-Scale Offshore Wind Power HVDC Direct Transmission to Load Centers
摘要
Abstract
The large-scale development of offshore wind power is one of the key measures to achieve the"dual carbon"goals.To ad-dress the future demand for centralized offshore wind power development and transmission,an analysis of influencing factors and construction principles is conducted for the topology selection of offshore wind power direct current(DC)transmission to load centers.Firstly,against the backdrop of expanding offshore wind power transmission scale,the necessity of transmitting offshore wind power via overhead DC lines directly to load centers after onshore connection is discussed.Then,from five perspectives which are offshore wind power aggregation schemes,multi-terminal DC network topologies,DC fault isolation,offshore converter station topologies,and flexible DC system receiving-end connection methods,the influencing factors for topology selection in large-scale offshore wind power DC grid integration are analyzed.Correspondingly,construction principles for offshore wind power DC transmission to load centers are proposed.Finally,a multi-terminal DC system for offshore wind power is constructed in a specific regional power grid demonstrating the feasibility of the proposed construction principles.关键词
