1. 1. Impact from flexible operation on High Head Francis turbines

   University essay from KTH/Hållfasthetslära (Avd.)

   Author : Andreas Skorpen; [2018]
   Keywords : ;

   Abstract : Today the European energy grid contains more renewable energy sources than ever before, yet there is little to no research on how the increased amount affects the cost structure of the remaining energy sources of the grid. A consequence of phasing more renewable energy sources into the power grid, is a reduction of the overall balancing capacity of the grid. READ MORE
