摘要
This invention discloses a controller and method for a cyber synchronous machine (CSM, in short, cybersync machine), namely, a power electronic converter that is seamlessly equipped with computational algorithms (i.e., the controller) to represent the intrinsic and fundamental principles of physical synchronous machines. The CSM can be operated in the grid-connected mode or the islanded mode to take part in the regulation of the frequency and the voltage. The controller also includes auxiliary blocks to achieve self-synchronization without measuring or estimating the grid frequency and the regulation of real power and reactive power to the given reference values without static errors. The control signal for the power electronic converter can be the output voltage generated by the engendering block or the sum of the output voltage and the virtual current. A unique feature of the disclosed CSM is that, if the system it is connected to is passive, then the whole system is passive and, hence, is guaranteed to be stable.
