1 INTRODUCTION. Virtual synchronous generator technology simulates the external characteristics of traditional synchronous generators, which not only makes the microgrid inverter have the steady-state characteristics of
The inverter is a key link in the power electronic converter, which affects the power quality of entire microgrid 3. However, conventional inverter control methods can easily lead to poor control performance in complex engineering conditions, which can have adverse effects on the power quality of microgrids.
In view of this, research will introduce ACS based on the integration of Narendra, hoping to improve microgrid inverters’ control stability. Microgrid 16, 17, 18, 19, 20 inverter ACSY is an intelligent control system that can automatically adjust control strategies based on changes in network parameters.
Vemula NK and Parida SK have studied the control of microgrids in China. In order to improve the stability of the system and the small signal stability and transient response of inverters under different operating conditions, a droop control scheme based on optimal internal model control is proposed.
Frequency control and regulation in a microgrid can be realized by a distributed power supply, energy storage device, etc. EVs can also participate in microgrid frequency regulation as a part of the controllable load.
The second part first introduces the adaptive control system (ACSY) for microgrid inverters that integrate Narendra model, and then makes improvements based on this. Next, the performance of Narendra based microgrid inverter ACS was verified, and performance testing and comparative analysis experiments were conducted.
In recent years, microgrid technology has been widely studied and applied. However, with times developing, the installed capacity of distributed power generation devices has been improved, and work is being carried out in increasingly complex situations, resulting in a decline in the control performance of microgrids.
