摘要

Rapid growing on the power level of renewable generation units leads to that using more adaptable and flexible control techniques in this units becomes more important for grid operators. In this paper, after introducing Renewable Static Synchronous Generation Units (RSSGU) as units with flexible dynamics capability, forming of renewable Virtual Power Plants based on this RSSGUs (VPP-SSG) is suggested as a solution for overcoming phase stability challenges on interconnected generation areas. Based on the dynamic modeling and small signal analysis, an algorithm is presented for the dynamic designing of VPP-SSGs aims to provide supporting damping for both local and interarea oscillatory modes. Modal analysis and time domain study on active powers inside of generation areas and tie lines on two area system using Simulink confirms that these type of VPP-SSGs can support phase stability on power grid with interconnected generation areas.
