Grid stability with renewables? Yes, Wind can!

A primary advantage that synchronous generators deliver is mechanical inertia which instantly resists speed changes in a grid shock, such as the failure of a large power plant or a transmission line. Generator speed determines grid frequency. The larger the shock or the lower the inertia, the faster the rate of change of frequency. Therefore grids need inertia for stability. Most wind turbine systems provide asynchronously generated energy which contribute no inertia because their spinning masses are decoupled electronically from the grid, although it is suggested this may be overcome via untested synthetic inertia (also known as Fast Frequency Response "FFR") to respond to grid shocks via their power electronics. Solar panels can not provide this due to the lack of a spinning mass.
WTL's drive-train enables its synchronous generator to be directly connected to the grid, providing inertia for instantaneous grid stability the same as traditional power generators, without power electronics. This delivers direct resistance to frequency change as opposed to only providing the proposed response of FFR that most existing wind turbine systems expect to offer. WTL's system has been IEC certified by
- Voltage support through a full range of reactive power capabilities;
- System strength by providing huge "fault currents" (5-10 times rated) to rectify voltage faults;
- Synchronous condenser mode even with no wind; and
- Controllable power level and ramp rates.
WTL welcomes the release last Friday by the Australian Chief Scientist,
WTL's system has recently been extended with a new patented system to enable broad-band variable-speed operation which wind turbines require in lower wind climates. WTL CEO
As the world moves to renewable energy, it will become an issue for all nations as the 21st century progresses.
WTL is actively seeking partnerships with wind turbine manufacturers who are at the forefront of wind energy and interested to license WTL's proven drive-train technology.
WTL is also pleased to communicate directly with grid operators, consultants, academics, journalists and other parties interested in issues in grid stability. For further information, please contact email@example.com or call +64-3-365-8960.
