完全可再生欧洲电力系统的输电需求

Transmission needs across a fully renewable European power system

Rolando A. Rodriguez, Sarah Becker, Gorm B. Andresen, Dominik Heide, Martin Greiner

摘要:

剩余负荷和过剩发电的27个欧洲国家的可变可再生能源的渗透率为100%,探讨以量化国家之间的电力传输的好处。估计数是基于广泛的天气数据,这使得建模的需求和可再生能源发电从风能和太阳能光伏发电之间的每小时不匹配。对于独立的国家,平衡需要覆盖年能源消耗总量的24%左右。一旦所有国家都通过不受约束的互联网连接在一起,这个数字可以降低到15%。这一减少代表了传输给各国可能带来的最大利益。无约束互连的总净传输容量大约是当前值的十二倍。然而,约束互连能力比目前的值大六倍,发现提供97%的最大可能的合作效益。这促使对几种受限的传输容量布局进行详细调查,以确定参与完全可再生欧洲电力系统的国家的出口和进口能力。

英文摘要:

The residual load and excess power generation of 27 European countries with a 100% penetration of variable renewable energy sources are explored in order to quantify the benefit of power transmission between countries. Estimates are based on extensive weather data, which allows for modelling of hourly mismatches between the demand and renewable generation from wind and solar photovoltaics. For separated countries, balancing is required to cover around 24% of the total annual energy consumption. This number can be reduced down to 15% once all countries are networked together with uncon- strained interconnectors. The reduction represents the maximum possible benefit of transmission for the countries. The total Net Transfer Capacity of the unconstrained interconnectors is roughly twelve times larger than current values. However, constrained interconnector capacities six times larger than the current values are found to provide 97% of the maximum possible benefit of cooperation. This motivates a detailed investigation of several constrained transmission capacity layouts to determine the export and import capabilities of countries participating in a fully renewable European electricity system.
