Title: Power electronic converters that take part in the grid regulation without affecting the DC-port operation
Inventor: QINGCHANG ZHONG
IPC: H02M7/797
Filed: 2017-10-26
Abstract: A DC/AC power electronic converter comprises a DC port, an AC port and a storage port for the connection of storage units. A PWM block generates pulses to operate the converter. A subtraction block subtracts a first voltage signal from a second voltage signal to generate an input for the PWM block, where the first signal is generated by an inner loop controller according to grid voltage and current, and the second signal is generated by a power controller that regulates the real and reactive power exchanged with the grid. A storage voltage controller regulates the voltage of the storage port to generate a real power set point for the power controller while taking into account the DC port power. The DC/AC power electronic converter system can be used to support the grid without affecting the normal operation of the DC port. The DC port may be either connected to a load when operated as a rectifier or to a DC source when operated as an inverter. The arrangement enables rectifier-fed loads to provide continuous demand response and inverter-fed sources to provide continuous frequency response.
