19 Test Case #3 Hard Trigger Islanding (1 sec Early Warning) 12. November 2008, 10:55 11:19 At time of island, cell generation (which includes over 1 MW of wind power) exceeds load by 470 kw. Frequency increases immediately, but SLC and CHP governors react to compensate. During island, cell frequency fluctuates as wind generation varies from 800 to 1350 kw. Cell Controller reacts and maintains cell within all grid code given boundaries. Cell reconnected to grid. 18

20 Test Case #3 Hard Trigger Islanding (1 sec Early Warning) 12. November 2008, 10:55 11:19 Once a reconnection to the grid is requested, the Cell Controller brings cell frequency and voltage phase within range of grid values. The Master Synchronizer reconnects only when cell frequency and voltage phase are sufficiently close to the grid values. 19

21 Achieved test results from Area 1 Grid connected import/export control (virtual generator operation) Emergency transfer to sustained hybrid island operation Islanded wind only operation with SC and SLC In conclusion: We believe we have successfully demonstrated the first utility scale SmartGrid concept worldwide 20
