UNIQUE VIRTUAL POWER SYSTEM TECHNOLOGY USED IN A LOW POWER NETWORK TO PROVIDE SOLUTION TESTING FOR DISTRIBUTED GENERATION

摘要

To fully test electrical machines, it is desirable to have full control over the network to which they are connected. Control of the networks impedance, voltage, and frequency, and the ability to be able to test machines under network fault conditions are all desirable attributes for a test facility. There is particular interest in testing machines at present, since the machine parameters for generating electricity from intermittent renewable sources are unlike those parameters from gas or steam turbines, and there are concerns relating to grid stability under scenarios with high penetrations of renewable generators.
