  "textContent": "Provided is a method for operating a wind power installation or a wind farm with a number of wind power installations for exchanging electrical power between the wind farm and an electrical supply grid. Each wind power installation has one or more feeding-in devices. The wind power installation or the wind farm is connected to the electrical supply grid by a grid connection point. The power is exchanged by way of the grid connection point. One or more of the feeding-in devices operate as voltage-impressing units and one or more of the feeding-in devices operate as current-impressing units. The voltage-impressing units and the current-impressing units also operate in a voltage-impressing and current-impressing manner during undisturbed operation of the electrical supply grid.",
