1. A wind energy system, comprising:
a plurality of wind turbines connected to at least one cable network,
wherein the at least one cable network is configured to transmit electrical power fed-in by the connected plurality of wind turbines,
at least one control apparatus configured to control the electrical power fed into the at least one cable network by at least one of the plurality of wind turbines by providing at least one power set point,
at least one temperature detecting device configured to detect a temperature of the at least one cable network,
at least one condition detecting device configured to detect a condition of the wind energy system,
wherein the at least one control apparatus comprises at least one control device configured to determine the at least one power set point based on the detected temperature and the detected condition,
wherein the at least one condition detecting device comprises at least one switching condition evaluating module configured to determine electrical topology of the wind energy system based on switching states of a plurality of electrical switching devices of the wind energy system, and
wherein the at least one control device is further configured at least to determine the at least one power set point based on the determined electrical topology of the wind energy system.
