Geographically Dispersed Wind Turbines on the West-estonian Coast

Estonian farms are connected to the common grid practically for 100%. Therefore efforts to improve the share of renewable energy resources in the agriculture must consider the impact on the common grid. Estonia is rich of wind energy, but its random character and rapid changes in velocity (causing high wind power increments) create problems for the wind turbines to be matched with the existing power supply. The geographical dispersion of wind turbines will help to reduce their total wind power increment and impact on the common gird. This effect has been studied by two different approaches at four separated sites on the Estonian western coast. Both methods show that the resulting power increment can be suppressed up to 3 – 5 times if the number of sites exceeds 3 – 5.
