Abstract

With the successive proposal of carbon reduction goals in various countries, offshore wind power has gradually become one of the important forms of energy in some countries. The contradiction between the consumption of large-scale offshore wind power and the shortage of flexibility resources of the receiving-end grid has become increasingly prominent. It is urgent to improve the flexibility of large-scale offshore wind power. Based on the advantages of VSCHVDC in the long-distance transmission of offshore wind power, this paper proposes a planning method for VSC-MTDC systems of offshore wind power integration considering flexible operation characteristics. A flexibility model of VSC-MTDC systems for offshore wind power integration is built. Incorporating the flexible operation requirements of offshore wind power integration into the planning of electrical systems, a bilevel optimization model is proposed. The upper layer plans the electrical system under steady-state scenarios, and the lower layer performs the operation verification under wind speed fluctuation scenarios. The case study based on MATLAB R2020a shows that the proposed method can provide flexible and adjustable wind power for the onshore grid as much as possible while saving investment costs, which can provide a reference for the engineering design of offshore wind power integration systems based on MTDC.

期刊介绍： Electric Power Systems Research is an international medium for the publication of original papers concerned with the generation, transmission, distribution and utilization of electrical energy. The journal aims at presenting important results of work in this field, whether in the form of applied research, development of new procedures or components, orginal application of existing knowledge or new designapproaches. The scope of Electric Power Systems Research is broad, encompassing all aspects of electric power systems. The following list of topics is not intended to be exhaustive, but rather to indicate topics that fall within the journal purview. • Generation techniques ranging from advances in conventional electromechanical methods, through nuclear power generation, to renewable energy generation. • Transmission, spanning the broad area from UHV (ac and dc) to network operation and protection, line routing and design. • Substation work: equipment design, protection and control systems. • Distribution techniques, equipment development, and smart grids. • The utilization area from energy efficiency to distributed load levelling techniques. • Systems studies including control techniques, planning, optimization methods, stability, security assessment and insulation coordination.
