Abstract
A method of controlling a wind power plant is disclosed. The wind power plant includes an energy storage device and is connected to a power grid. The wind power plant also includes one or more wind turbine generators that produce electrical power for delivery to the power grid. The method includes: processing input data related to one or more inputs to the wind power plant to determine a probability forecast for each input; and controlling charging and discharging of the energy storage device in accordance with each probability forecast and a prescribed probability of violating one or more grid requirements.

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 input data related to one or more inputs to the wind power plant to determine a probability forecast for each of the one or more inputs;
- determining a set of chance-constraints relating to operation of the wind power plant;
- determining respective limits for each chance-constraint of the set, the limits being determined in accordance with a prescribed probability of violating one or more grid requirements;
- determining, based on each chance-constraint limit and each probability forecast, a set of device constraints relating to charging and/or discharging of the energy storage device;
- and
- controlling charging and discharging of the energy storage device in accordance with each probability forecast and the prescribed probability of violating the one or more grid requirements and to avoid violating the device constraints.
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:
- a processing module configured to:
- process input data related to one or more inputs to the wind power plant so as to determine a probability forecast for each of the one or more inputs;
- generate a control signal arranged to control charging and discharging of the energy storage device in accordance with each probability forecast;
- determine a set of chance-constraints relating to operation of the wind power plant;
- determine respective limits for each chance-constraint of the set, the limits being determined in accordance with a prescribed probability of violating one or more grid requirements;
- determine, based on each chance-constraint limit and each probability forecast, a set of device constraints relating to charging and/or discharging of the energy storage device;
- and
- control charging and discharging of the energy storage device in accordance with each probability forecast and the prescribed probability of violating the one or more grid requirements and to avoid violating the device constraints, by outputting the control signal.

- generate a control signal arranged to control charging and discharging of the energy storage device in accordance with each probability forecast;
- determine a set of chance-constraints relating to operation of the wind power plant;
- determine respective limits for each chance-constraint of the set, the limits being determined in accordance with a prescribed probability of violating one or more grid requirements;
- determine, based on each chance-constraint limit and each probability forecast, a set of device constraints relating to charging and/or discharging of the energy storage device;
- and
- control charging and discharging of the energy storage device in accordance with each probability forecast and the prescribed probability of violating the one or more grid requirements and to avoid violating the device constraints, by outputting the control signal.
