The utilization of renewable sources brings many benefits to electric power systems, but also some challenges like the impact that renewable power plants employing power electronics have on the grid, which is gaining importance as the penetration of this type of generating stations increases, driven by the construction of large wind or solar photovoltaic power plants. This paper analyses the im...

The European Union aims at largely decarbonizing its energy system by 2050. In this context, this paper reviews the status of the solar electricity technologies that can exploit our largest renewable energy resource. Although substantial progress is being made, the possibility, for instance, to more than double the efficiency of photovoltaic systems underlines the continued need for coordinated...
