The employment of High-Voltage Direct Current (HVDC) transmission in modern power systems is mainly driven by requirements of increasing power transfer over high distances in a cost-efficient and controllable way. HVDC control can ensure fast and accurate power flow control to improve the whole system performance as well as increased flexibility to manage power flows from remote renewable generation to load centers, especially in a zonal market configuration. However, in the network planning phase the implications of a new HVDC connection, both on the steady-state and on the dynamic operation of a power system, must be carefully evaluated with particular reference to possible outage events, depending on the operating conditions and on the exploited control schemes. In this paper, a real HVDC project within the Italian transmission network is considered in both the Voltage Source Converter (VSC) and Line Commutated Converter (LCC) technologies. The study implies a methodology to analyze the impact on steady-state and dynamic performances in the presence of faults, with a focus on grid security and market efficiency aspects. The behavior of the interconnected Italian power system is simulated in a development planning viewpoint by means of software tools exploited by the System Operator.

实际 HVDC 链路项目不同架构的静态和动态评估

高压直流 (HVDC) 传输在现代电力系统中的应用主要是由以经济高效和可控的方式增加远距离电力传输的要求驱动的。HVDC 控制可以确保快速准确的潮流控制，以提高整个系统的性能，并提高管理从远程可再生能源发电到负荷中心的潮流的灵活性，尤其是在区域市场配置中。然而，在网络规划阶段，必须仔细评估新的 HVDC 连接对电力系统稳态和动态运行的影响，特别是参考可能的停电事件，具体取决于运行条件和被利用的控制方案。在本文中，电压源换流器 (VSC) 和线路换向换流器 (LCC) 技术都考虑了意大利输电网络内的一个真正的 HVDC 项目。该研究暗示了一种方法来分析存在故障时对稳态和动态性能的影响，重点是电网安全和市场效率方面。互连的意大利电力系统的行为通过系统运营商开发的软件工具在开发规划的角度进行模拟。
