Electricity self-consumption consists in consumers installing their own small generators, solar photovoltaics mainly. They attempt to save money in the electric bill by producing part of their electrical energy, consequently reducing dependency on the distribution grid. Consumers that simultaneously become producers are usually known as prosumers. This work shows the techno-economical implications, in terms of electric energy, cost savings and grid voltage impact, if self-consumption is deployed in a European low voltage feeder. In the case study, the IEEE European LV test feeder was used. Real data for solar irradiance from 1985 to 2017 were considered for Gijón, a city in the North of Spain. Conclusions may be extrapolated to different locations.

电力自耗包括消费者安装自己的小型发电机，主要是太阳能光伏发电。他们试图通过产生一部分电能来节省电费，从而减少对配电网的依赖。能同时成为生产者通常被称为消费者个人用户。这项工作表明，如果在欧洲低压馈线上部署自耗技术，则在电能，成本节省和电网电压影响方面将产生技术经济意义。在案例研究中，使用了IEEE欧洲LV测试馈线。考虑了西班牙北部城市希洪（Gijón）1985年至2017年太阳辐射的真实数据。结论可能外推到不同的位置。
