Abstract The liberalisation of electricity markets and increasing penetration of renewable generation are encouraging trading opportunities to be identified and developed. In Europe, the importance of interconnection is well recognised. Interconnections are particularly important for islanded nations, like Great Britain, which provides access to generation and demand across the national boundaries via sub-sea HVDC cables while providing means to share reserves enhancing the security of supply and reducing overall costs. There are plans in place to significantly increase the current 5 GW of interconnection capacity between GB and neighbouring European countries. The paper investigates the expected impacts that a large increase in interconnection capacity could have on key electricity market parameters such as marginal prices, carbon emissions and the nature of utilisation of existing and future GB interconnections. Several scenarios have been considered to model future uncertainty for the years 2020 and 2025.

评估增加 GB 互连的价值

摘要 电力市场的自由化和可再生能源发电的日益普及正在鼓励确定和开发交易机会。在欧洲，互连的重要性已得到广泛认可。互连对于岛国尤其重要，例如英国，它通过海底高压直流电缆提供跨越国界的发电和需求接入，同时提供共享储备的手段，以提高供应安全并降低总体成本。有计划显着增加 GB 与欧洲邻国之间目前 5 吉瓦的互连容量。该论文调查了互连容量的大幅增加可能对关键电力市场参数（例如边际价格、碳排放以及利用现有和未来 GB 互连的性质。已经考虑了几种情景来模拟 2020 年和 2025 年的未来不确定性。
