Wind turbine management system for controlled energy storage
| DWPI Title: Wind turbine management system for being connected to electrical grid to control e.g. torque modulation, of electrical output of wind turbine, has processor for inputting characteristics into controller to regulate operation of turbines |
| Abstract: A system and method of managing a wind turbine, by receiving one or more characteristics from a first grid node from one or more grid sensors at a first time and receiving one or more characteristics from a second grid node from one or more grid sensors at a second time. The system and method also determine a power output requirement based on the one or more characteristics from the first grid node and the second grid node and regulate the operation of the wind turbine, based on the power output requirement by causing the blade rotational speed of the wind turbine to oscillate. |
| Use: Wind turbine management system for being connected to an electrical grid to control operations e.g. torque modulation, blade pitch modulation and power modulation, of an electrical output of a wind turbine. |
| Advantage: The system modulates wind power output around an optimal set point by using torque control to provide balancing, frequency and stability services to the grid or a microgrid without a reduction in energy production. The system allows a wind turbine management or a control system to control wind turbine's operations, so that inertial energy stored within wind turbine blades can be increased or decreased, thus actuating a variety of local and wide-area control functions. The system manages system stability and balance by storing and release of rotational kinetic energy in the wind turbines so as to provide grid services, thus increasing grid flexibility and resilience. The system modulates power output to the grid for performing ancillary grid services such as grid stability and managing system balance and transmission and generation system stability when the wind turbine is utilized to provide transmission system balancing services, thus modulating the wind turbine power output, hence increasing system frequency. The system optimally combines the blade pitch modulation with the torque modulation so as to increase modulation capacity, thus minimizing combined modulation losses. |
| Novelty: The system (170) has a processor for receiving multiple characteristics from a first grid node (120) from multiple sensors at first time. The processor receives multiple characteristics from a second grid node (195) from the sensors at a second time. The processor inputs the characteristics into a controller (260) to regulate operation of multiple wind turbines (220) by modulating wind power output of the wind turbines without reduction in the wind power output using torque control, where speed of rotation of the wind turbines oscillates between first and second blade rotational speed, and the first blade rotational speed is less than the second blade rotational speed, and the first time and the second time are same. |
