Abstract

Abstract: Characteristics of urban power supply system are analyzed. With improvement on IEEE-13 distribution system, a distribution system model is designed to improve system supply reliability and power quality. In order to prevent multi-terminal HVDC system instability caused by faults on AC end, a model-free adaptive control(MFAC) technology is proposed. When AC system fault occurs, traditional PID controller has bad performance due to large system parameter disturbance. The DSC inverter controller based on MFAC technology discards need of detailed control system model without losing control capability. Simulation results under different abnormal operating conditions verify feasibility and effectiveness of proposed design.

Key words: multi-terminal DC, urban power supply, VSC, model-free adaptive, AC-DC hybrid power distribution
