“…The small disturbance stability of the power system could be measured with damping ratio under different oscillation modes. 18 When damping ratio is larger, the system under the mode is more stable, or vice versa. Based on this, this paper adopted the BPA software to analyze small disturbance voltage of the system after IGS integration, search for all 0.1 to 2.5-Hz low damping modes and select minimal damping ratio ξ min as system small disturbance stability assessment indicator under IGS scenario.…”

Summary Accurately assessing the influence of intermittent generation integration upon grid security bears great significance to large‐scale intermittent generation planning and grid‐connected operation. Starting from the two aspects of static security and dynamic security, this paper chooses eight indicators that can reflect the influence of intermittent generation integration upon grid security and provides the calculation methods of each indicator. Given the differentiation of the influence of different intermittent generation integration scenarios upon grid security and the absence of unified assessment standards, this paper utilizes the theory of relative competition to propose a yardstick competition based single indicator assessment method, so as to determine the weight with variation coefficient and adopt gray correlation analysis method to build a comprehensive assessment model. Then, making use of the method proposed, it assesses the wind power and photovoltaic integration planning in Zhejiang Province, China in 2020, analyzes the grid security features, differences and potential problems of wind power and photovoltaic power in different regions and under different integration rates, and ultimately offers corresponding countermeasures.

Abstract:Power system transient stability is a challenge when integrating large-scale wind turbines into weak grids. This paper addresses the issue of transient stability in such situations by optimizing a wind turbine's active current behavior. A wind turbine's active current reference controller and its setting optimization method are proposed based on analyses of two associated problems: the mechanism for improving transient stability of a single (synchronous) machine infinite bus (SMIB) system, as well as the various physical factor dependencies dictating how active and reactive wind turbine currents affect the swing dynamics of synchronous machines. Analysis of the first problem guided the design of the controller's main structure. Analysis of the second problem guided selection of the control object within a wind turbine's active and reactive currents, as well as helped recognition of the influential physical factors that must be considered in the parameter setting process. The efficiency of the controller and the validity of the analyses were verified by case studies using Kundur's two-area system.
