欧盟单一电力市场（ESEM）的既定目标是将欧盟电力市场联系起来，并在整个欧盟范围内获得独特的电价。这一目标将通过促进价格区之间的有效交易来实现。欧盟与ESEM共同制定了温室气体排放和可再生能源使用的宏伟目标：到2020年，减排目标比1990年降低20%，到2030年减排40%，到2050年减排85%，这将直接或间接促进对可再生能源的投资。到2030年，欧盟电力市场将发生巨大变化。对可再生能源的高投资与高效交易的必要性相关，可能会导致网络拥堵，从而提高欧盟电力系统的成本。在这项工作中，我们使用PLEXOS模型来验证2030年的网络拥塞水平，并根据10年网络发展计划（TYNDP）假设互联。我们确定在哪些方面进一步投资于互联可以有助于降低欧盟层面的系统成本。最优投资的选择在模型中是内生的。首先我们验证了欧盟国家的批发电价是如何变化的。其次，我们检查利润如何受到新投资的影响。最后，我们进行了福利分析，包括新的输电网投资所实现的排放节约。我们的研究结果表明，单个互联升级降低了系统总成本，从而增加了欧盟层面的净福利。此外，由于互联程度的提高，可以观察到从生产者剩余到消费者剩余的转变。
The stated aim of the EU Single Electricity Market (ESEM) is to link together EU electricity markets and get a unique electricity price across the EU. This target will be met by promoting efficient trading between price zones. Jointly with the ESEM, the EU has set separate ambitious targets for greenhouse gas emissions and renewable energy use: for emissions reduction these are stated as 20% lower than 1990 levels by 2020, rising to 40% lower by 2030 and 85% lower by 2050 that will directly and indirectly promote the investment in renewables. By 2030, massive changes in EU electricity markets will take place. High investments in renewables associated with the necessity of efficient trades may result in network congestion, which rises the costs of the EU electricity system. In this work we use a PLEXOS model to verify the level of network congestion in 2030 and assuming interconnection according to the 10 year network development plan (TYNDP). We determine where further investment in interconnection can contribute to decreasing system costs at the EU level. The choice of the optimal investment is endogenised in the model. First we verify how the wholesale electricity prices change in EU countries. Second we check how profits are affected by the new investments. Finally we perform a welfare analysis including the emission savings achieved with the new investments in transmission networks. Our results indicate that individual interconnection upgrades reduce total system costs and therefore increase net welfare at the EU level. In addition, a shift from producer surplus to consumer surplus can be observed as a result of a higher level of interconnection.
