In order to enhance the adaptability of grid-connected inverters under these abnormal conditions, this research systematically summarizes and concludes a series of inverter adaptive control strategies, which provide literature guidance to effectively reduce the probability of power system faults and improve the reliability of the power system.
Adaptive Control Strategy of Grid-Connected Inverter 3.1. Adaptive Control Strategy of Power Grid Voltage PV inverters need to control the grid-connected current to keep synchronization with the grid voltage during the grid-connection process.
In the comparison between the improved inverter adaptive control system and the inverter adaptive system, the improved inverter voltage recovery speed is faster, can be restored within one cycle, and the control effect of the inverter is better. The harmonic rate of the port voltage has decreased from 10.43 to 1.92%.
Conclusion In this paper, a novel adaptive controller is proposed for GFM inverter based on steady-state inverter control requirements. Two kinds of inputs are designed in control input, namely power control input and signal control input. The former improves dynamic performance and disturbance-resistant ability.
Our photovoltaic systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
