考虑光热电站接入的电力系统暂态功角稳定性分析
Transient Power Angle Stability Analysis of Power System Considering the Access of Concentrated Solar Power Plant
摘要
Abstract
Concentrated solar power(CSP)generation exhibits a dual functionality of peak load regulation and ener-gy storage,offering rotational inertia and damping support to the renewable energy power system.However,its influ-ence on the stability of power system remains unclear.As for the influence and its mechanism of integration of CSP in-to power system on the transient stability of system,an equivalent model of CSP plants based on the capacity-weight-ing method is set up firstly.Then,considering the low inertia characteristics of CSP plants,the extended equal-area criterion(EEAC)is used to analyze the influence of inertia reduction on the transient power angle stability of the sys-tem.The research results show that in a single-machine infinite bus system,the substitution of thermal power units with CSP plants at equivalent capacity results in a reduction of system inertia and a weakening of transient power an-gle stability.Finally,the influence of large-scale integration of CSP on transient stability of power system is simulated and analyzed on the basis of a regional power grid.关键词
