<p>The object of the invention is an elevator system and a method for controlling an elevator group. The elevator system according to the invention comprises an elevator group, which comprises at least two elevator cars (1, 1'), which elevator cars are fitted to be moved in the elevator hoistway (2, 2') according to the calls allocated by the control (3) of the elevator group. The elevator system comprises a power supply arrangement (5, 5'), for adjusting the power needed to move the elevator cars (1, 1'). An energy storage (6, 6') is connected to the power supply arrangement. The energy storage is fitted in the first operating situation to yield energy for use in moving the elevator car, and in the second operating situation to receive energy released by movement of the elevator car. The elevator system comprises a determination of the charging status of the energy storage, and the control (3) of the elevator group is fitted to determine the change in energy that would be caused by the movement according to an allocated call of the elevator cars (1, 1') belonging to the elevator group. The control (3) of the elevator group is fitted to allocate a call by favoring in the allocation an elevator car (1, 1' ), the determined change in energy caused by the movement of which best meets the allocation criterion.</p> |
