Abstract
A method of controlling a wind power plant including an energy storage device, the wind power plant being connected to a power grid and comprising one or more wind turbine generators that produce electrical power for delivery to the power grid, the method comprising: processing grid data related to the power grid to determine a probability forecast for a future state of the grid; and controlling charging and discharging of the energy storage device in accordance with the probability forecast.

A method of controlling a wind power plant including an energy storage device, the wind power plant being connected to a power grid and comprising one or more wind turbine generators that produce electrical power for delivery to the power grid, the method comprising:
- processing grid data related to the power grid to determine a probability forecast for a future state of the power grid, wherein the probability forecast for the future state of the power grid provides an indication of relative probabilities of a range of future grid events possibly occurring on the power grid over a time window, wherein the range of future grid events includes:
- i) fault events resulting from under voltage or frequency on the power grid;
- and ii) at least one of the following grid events:
- changes in power consumption by loads connected to the power grid;
- adding new loads to the power grid;
- and real-time electricity price fluctuations associated with the power grid;
- and
- controlling charging and discharging of the energy storage device in accordance with the probability forecast.
A control system for a wind power plant including an energy storage device, the wind power plant being connected to a power grid and comprising one or more wind turbine generators that produce electrical power for delivery to the power grid, the control system comprising:
- an input configured to receive grid data related to the power grid;
- a processing module configured to:
- process the grid data to determine a probability forecast for a future state of the grid, wherein the probability forecast for the future state of the power grid provides an indication of relative probabilities of a range of future grid events possibly occurring on the power grid over a time window, wherein the range of future grid events includes:
- i) fault events resulting from under voltage or frequency on the power grid;
- and ii) at least one of the following grid events:
- changes in power consumption by loads connected to the power grid;
- adding new loads to the power grid;
- and real-time electricity price fluctuations associated with the power grid;
- and
- generate a control signal arranged to control charging and discharging of the energy storage device in accordance with the probability forecast;
- and
- an output configured to output the control signal.
A wind power plant connected to a power grid, comprising:
- an energy storage device;
- at least one wind turbine, comprising:
- a tower;
- a nacelle disposed on the tower;
- a generator disposed in the nacelle and configured to produce electrical power for delivery to the power grid;
- a rotor coupled to the generator;
- and
- a plurality of blades disposed at a distal end of the rotor;
- and
- a control system, comprising:
- an input configured to receive grid data related to the power grid;
- a processing module configured to:
- process the grid data to determine a probability forecast for a future state of the grid, wherein the probability forecast for the future state of the power grid provides an indication of relative probabilities of a range of future grid events possibly occurring on the power grid over a time window, wherein the range of future grid events includes:
- i) fault events resulting from under voltage or frequency on the power grid;
- and ii) at least one of the following grid events:
- changes in power consumption by loads connected to the power grid;
- adding new loads to the power grid;
- and real-time electricity price fluctuations associated with the power grid;
- and
- generate a control signal arranged to control charging and discharging of the energy storage device in accordance with the probability forecast;
- and
- an output configured to output the control signal.
