An electrical energy distribution grid is controlled by a control center. Power target values for the real power and reactive power at a transfer point between the energy distribution grid and an electrical energy transport grid are prescribed by a target value device. The target values are to avoid backward feed into the energy transport grid that could lead to malfunctions. The real and reactive power target values are compared with current values at the transfer point. When a deviation of the actual values is determined, an optimization calculation is effected for the real power value and the reactive power value in the energy distribution grid to reduce or remove the deviation. The optimization generates switching commands for controllable operating devices, and a control device transmits the switching commands to the operating devices. There is also described a control center arrangement and a corresponding computer program product.
