A Graphical Modeling Method Applied for Multi-Sources System Subsynchronous Oscillation Analysis
摘要
Abstract
Multi-sources have participated in the subsynchronous oscillation of renewable energy power system. Conventional approach for state space modeling of multi-sources system is difficult to be employed in the situations where wind power, photovoltaic and thermal power operate parallelly. This paper presents a graphical modeling method, based on a graphical model library containing basic units in the form of state space model. The proposed method can establish the state space according to complex system visually. In addition, it is more convenient for the source-to-grid interface processing. The study case of IEEE first benchmark model for subsynchrnous oscillation verified the proposed method. What's more, a state space pertaining to the multi-sources system was modeled, where wind power bundled with thermal power transmitted through HVDC line. The influence of wind power on subsynchronous torsional modes belonging to thermal generator was studied. The advantages of graphical modeling method over conventional approach are strong independence, high flexibility, good visibility and strong extensibility.关键词
