A method for controlling an electricity distribution grid having a nominal grid voltage, in particular in a critical grid situation, wherein a grid control center is provided for controlling the electricity distribution grid and the electricity distribution grid has at least one control region that comprises a plurality of mutually geographically separate wind farms, comprising the steps of: querying power outputs available from the wind farms, in particular on the basis of a weather forecast; defining a control node within the control region, in particular on the basis of the queried available power out-puts, preferably performed by the grid operator; combining a number of wind farms at the calculated control node to form a wind power plant on the basis of the queried available power outputs and/or a probability distribution of the available power output; controlling the wind power plant, in particular through the grid control center, by way of a wind power plant control unit, such that a required voltage quality and/or frequency stability and/or uninterrupted availability is provided in the control region.

Dynamic wind-energy plant

A method for controlling an electrical distribution grid, comprising the following steps: determining at least one variable which describes a state of the electrical distribution grid; combining a plurality of electrical installations, in particular a plurality of regenerative generating units, of the electrical distribution grid to form a virtual power plant, in particular taking into consideration the variable; establishing a control area within the electrical distribution grid for the virtual power plant; establishing a control unit of an electrical installation of the virtual power plant as main control unit; controlling the control area using the main control unit of the virtual power plant.

Method for dynamic clustering of electrical installations, in particular for rendering ancillary services

A method for operating a charging station for charging a plurality of electric vehicles, in particular electric automobiles, wherein the charging station is connected to an electricity supply grid at a grid connection point in order thereby to be supplied with electrical energy from the electricity supply grid, the grid connection point is arranged on a first grid section of the supply grid and at least one further electrical consumer is connected to at least one second grid section of the supply grid, the first and the second grid section are connected to one another, the at least one further consumer and/or the at least one second grid section are able to be influenced by the charging station, the charging station is controlled such that a grid voltage in at least one of the grid sections is controlled, and/or a power flow at least in the at least one second grid section is controlled.

Charging station for charging multiple electric vehicles, in particular electric cars

A method for controlling an electrical distribution network, wherein a network control station is provided to control the electrical distribution network and the electrical distribution network comprises a plurality of balancing areas, wherein each balancing area outputs or receives an exchange power to or from the electrical distribution network, and wherein at least one of the balancing areas has at least one generator, in particular a wind farm, for generating a generator power and additionally at least one consumer for receiving a consumer power, wherein at least one balancing area controller is provided to control the at least one generator or wind farm, and the method comprises the following steps: reception by the balancing area controller from the network control station of a value of an exchange power to be set, wherein the exchange power is defined as a difference between the consumer power and the generator power, drawing up by the balancing area controller of a deployment plan for adherence to or attainment of the exchange power to be set, wherein the deployment plan is provided to control the generators and consumers and is drawn up in such a way that a difference between the attained exchange power and the exchange power to be set is minimal, and generation of electrical power by means of the at least one generator or wind farm depending on the deployment plan.
