Evaluation of the System-Aggregated Potentials of Inertial Support Capabilities from Wind Turbines
Paper in proceeding, 2019

The increasing shift from synchronous towards converter interfaced generation and consumption changes the mechanical inertia in power systems. Thus it is of great importance for system operators to estimate the potentials of inertial support from the wind turbines connected to their systems. This paper utilizes metereological re-analysis data in conjunction with a wind turbine database in a novel way to estimate the inertial support capabilities of all wind turbines in Sweden. Using the wind speed profile across the country for the years 2010 - 2015, a linear relation between energy production and inertial support capability of 1.3 W s / W is shown for the investigated inertial support approach. Furthermore, the results show that the 7.48 GW installed converter-interfaced wind turbines in Sweden can provide, on average, kinetic energy of 2.72 GWs and inertial support power of 0.27 GW, which is equivalent to 19.3% of the Nordic system dimensioning fault.
