| Abstract |
The stochastically fluctuating offer of wind energy
limits the supply capacity in electrical grids by means
of technical and economical reasons. To increase the supply,
a concept of dynamic conditioning with the objective to increase
the quality of supply was developed. The concept
envisages supporting and managing of the electrical grid
respectively by compensating active and reactive power with
static converters ("Electronic Synchronous Machine") and
short term storage. Short term fluctuation of the energy
sources and changes of the load can be absorbed or
smoothed directly on location using the four-quadrant operation
of the converters. Stochastically offered primary
energy is intermediately stored by using dynamic storage
systems. This low order energy can thereby be converted
into high order recallable energy, which can even be used to
satisfy peak demands. The local compensation of the fluctuating
energy supply on the one hand and of the changes of
the demand on the other hand, permits a more steady energy
demand from the nation-wide electrical grid. |
