Optimum Operational Planning of Wind-Integrated Power Systems With Embedded Multi-Terminal High Voltage Direct Current Links Using The Flexible Universal Branch Model

Abstract

This paper presents a comprehensive analysis of a meshed MT-HVDC topology with three wind farms connected to the Substation Ring Topology (SRT) and investigates the steady state performance of the MT-HVDC system based on the VSC control strategies (i.e. conventional method and droop control), which was modelled via the FUBM model and produced results that is useful for solving Optimal Power Flow, particularly in the systems where hybrid AC/DC are adopted to integrate with the large-scale wind resources. The main focus is on the impact evaluation of various VSC control strategies. The outcome indicated that the VSC based MT-HVDC system performs well in terms of power transmission stability and reliability. The operational gain of the simulation results is that the Electricity system operator has the preference for the most robust strategy for the operational planning depending on the system requirements.
