Abstract

A supercapacitor‐based coordinated synthetic inertia (SCSI) scheme for a voltage source converter‐based HVDC (VSC‐HVDC)‐integrated offshore wind farm (OWF) is proposed. The proposed SCSI allows the OWF to provide a designated inertial response to an onshore grid. Under the SCSI scheme, a supercapacitor is added to the DC side of each wind turbine generator via a bidirectional DC/DC converter, varying its voltage along with the offshore frequency to synthesise the desired inertial response. The HVDC grid side VSC employs a DC voltage/frequency droop control to convey the onshore frequency information to DC voltage without communication. Meanwhile, the wind farm side VSC regulates the offshore frequency to couple with the conveyed onshore frequency, considering voltage drop across the DC cables. An offshore frequency switching algorithm is incorporated to avoid undesired SCSI maloperation under offshore faults. The key parameters of the proposed SCSI are optimised through a small signal stability analysis. The effectiveness of the SCSI scheme is evaluated using a modified IEEE 39‐bus test system. The results show that the proposed SCSI scheme can provide required inertial support from WTG‐installed supercapacitors to the onshore grid through the VSC‐HVDC link, significantly improving the onshore frequency stability.

基于超级电容器的协调合成惯性方案，用于基于电压源变流器的 HVDC 集成海上风电场

针对基于电压源变流器的高压直流（VSC-HVDC）集成海上风电场（OWF），提出了一种基于超级电容器的协调合成惯性（SCSI）方案。拟议的 SCSI 允许海上风电场向陆上电网提供指定的惯性响应。在 SCSI 方案中，超级电容器通过双向 DC/DC 转换器被添加到每个风力涡轮发电机的直流侧，其电压随离岸频率变化，以合成所需的惯性响应。HVDC 电网侧 VSC 采用直流电压/频率下降控制，无需通信即可将陆上频率信息转换为直流电压。同时，考虑到直流电缆上的电压降，风电场侧可变电源调节器调节离岸频率，使其与传输的陆上频率耦合。此外，还采用了离岸频率切换算法，以避免在离岸故障情况下出现意外的 SCSI 误操作。通过小信号稳定性分析，对拟议 SCSI 的关键参数进行了优化。利用改进的 IEEE 39 总线测试系统对 SCSI 方案的有效性进行了评估。结果表明，建议的 SCSI 方案可通过 VSC-HVDC 链路从风电机组安装的超级电容器向陆上电网提供所需的惯性支持，从而显著改善陆上频率稳定性。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
