Symbiotic coupling of wind power and nuclear power generation

The coupling of wind power production as an intermittent supply to nuclear power generation as a base load supply is discussed. Wind turbines on a standby operational mode are net importers of power for their control and yaw mechanisms. They need a supply of about 5 kW of power from an existing grid. They also require the vicinity of a power grid with excess capacity to export their generated power. A choice is the construction of wind farms in the immediate vicinity low population density population zones around nuclear power plants. An example is the Grand Ridge wind farm adjacent to the LaSalle nuclear power plant near Versailles, Illinois. Since the best wind resources in the USA are located far from the industrial and population centers there is a need for connection to the grid trough High Voltage Direct Current (HVDC). Due to ramping considerations, the planned introduction of 20 percent of electrical wind production in the USA by 2020 would pose challenging grid stability issues. Energy storage alternatives such as hydrogen production, compressed air, flywheels, superconducting magnets and pumped storage, need serious consideration.
