For controlling a voltage in a power grid including a PV bus and a PQ bus, a first tolerance range for an active power of the PV bus and a second tolerance range for an active power of the PQ bus are received. A first value for a reactive power of the PQ bus is received. With that, a robust optimization process is run for a set of power flow equations. The first and second tolerance ranges and the first reactive power value are input to the robust optimization process using the first and second tolerance ranges as robust optimization uncertainty. With that, the robust optimization process determines a voltage set point for the PV bus so that the set of power flow equations is fulfilled for the first and second tolerance ranges. According to the determined voltage set point, a voltage at the PV bus is controlled.

After initial clusters having only one component are formed, a conditional probability P(Ci|C′k) is determined for the cluster Ci being included in an order on condition that cluster C′k is included in the order. If P(Ci|C′k) is greater than a first threshold value S1, a new cluster Cn having all the components of clusters Ci, C′k is formed and the operations are repeated until no new clusters are formed.

Methods and apparatuses for pattern recognition involve quantum-mechanical calculations. Pattern recognition can be achieved by considering a quantum system and its Hamiltonian dynamics. The dynamics are calculated on the basis of an initial Hamiltonian indicating an initial quantum state and on the basis of a final Hamiltonian. The final Hamiltonian depends on an input pattern and reference patterns. Transformations according to the Hamiltonian dynamics for the quantum system are applied to generate a final quantum state of said quantum system. Depending on said final quantum state a similarity between said input pattern and said reference patterns is determined.

An aspect of the invention relates to a method for determining positional data of at least one node of a network, said network comprising a number of nodes, whereby the positional data refers to an internal coordinate system. The method comprises the following steps: a) preparation of positional data for a sub-set of nodes, b) determination of separation data for the least one node, c) determination or, on repetition of step c), correction of the positional data for the at least one node, depending on the positional data from step a), the separation data determined in step b) and positional data of the at least one node and d) repetition of steps a) to c), until an interruption condition is fulfilled.
