Abstract
Compared with traditional AC grid,VSC-DC grid has strong advantages and has attracted great attention in the applications of renewable energy and other multi-energy access.To avoid the contention of voltage control among units of multi-terminal VSC-DC grid,this paper proposes a common DC voltage coordinated control method for multi-terminal VSC-DC grid.The proposed method uses the common DC voltage of multi-terminal VSC-DC grid as the public information source,based on different operational conditions of load units,renewable energy units,energy storage units and auxiliary power supply units,the common DC voltage of multi-terminal VSC-DC grid is controlled within the desired regions by renewable energy units,energy storage units and auxiliary power supply units respectively,then the voltage stability of the multi-terminal VSC-DC grid is well maintained.Finally,the simulation results by Saber software verify that the proposed control method can effectively control the common DC voltage of multi-terminal VSC-DC grid and maintain the balance of the system power.关键词
