Abstract: The present invention relates to wind energy park connected to an electrical grid, having airborne wind energy systems (AWES), e.g. with kites. The wind energy park has an electrical DC network connecting the plurality of AWES and a grid converter unit for converting DC to AC, and transmit AC to the electrical grid. The wind energy park control unit controls the AWES to produce electrical power to the electrical grid by alternating between a power production phase, and a recovery phase so to balance the supply of power to the electrical grid according a demanded setpoint. An advantage is that the grid converter may be smaller, as compared to an AC network, because the power is evened out with the negative power from the AWES being in recovery phase. In this way, the invention stabilizes the grid and has a grid forming capability.
