WPP Model in Power System Security Assessment

Abstract

The integration of wind power plants at large scale has an impact on the reliability, the stability and the security of power systems. Recent events such as the blackout of Australia in 2016, a power system with large participation of wind generation, have demonstrated the need for appropriate tools to simulate and assess the impacts of wind energy on the security of power systems. Therefore, this paper proposes the inclusion of wind power plants in the simulation and the analysis of cascading phenomena in the power system, to assess the impact of the high penetration of wind generation in the security assessment of the power system based on the well-known Manchester model. This paper proposes a model of wind power plants based on the scheme of connection to the transmission system in order to determine the response of a wind farm when a disturbance occurs in the power system and to obtain a behavior that resembles a situation real. The proposed methodology is tested in the IEEE RTS-system of 24 nodes, in which the impact on security is evaluated by increasing the participation of wind generation, and it is demonstrated that the security of the energy system is reduced by increasing the participation of this type of technology in the generation dispatch.
