ABSTRACT:Wind is a clean source of energy which is naturally available and has been replacing the harmful non-perennial conventional power plants such as Thermal, Hydro, Nuclear etc., The innovation in design has gradually reduced the cost to set up a wind power plant. This has increased the penetration of wind energy in the Distribution Network (DN). Being a seasonal power generation, wind energy integration in the distribution network has created many challenging issues like voltage stability, system reliability and power system network stability. Hence a thorough analysis of wind energy integration is needed to make the power system network more stable. This paper describes the dynamic behavior of the distribution system while integrating wind energy through time series analysis. The load flow is performed using Newton-Raphson method, with a variable load profile. Time series analysis is done which gives the performance characteristics of the system which is validated in a practical IEEE 123 test feeder. RESUMEN:El viento es una fuente limpia de energía, que es naturalmente disponible y ha estado reemplazando las centrales de energía eléctrica convencionales no perennes tales como trmicas, hidroelectricas,nucleares etc., La innovación en el diseño ha reducido gradualmente el costo de instalar una planta de energía eólica, aumentando la penetración de este tipo de energía en la Red de Distribución (DN)de energía. Al ser una generación de energía estacional, la integración de la energía eólica en la red de distribución ha creado muchos desafíos como la estabilidad del voltaje, la confiabilidad del sistema y la estabilidad de la red del sistema eléctrico. Por lo tanto, un análisis exhaustivo de la integración de la energía eólica es necesario para hacer el sistema de energía más estable. Este artículo describe el comportamiento dinámico del sistema de distribución al tiempo que integra la energía eólica mediante análisis de series de tiempo. El flujo de carga se realiza utilizando el método de Newton-Raphson, con un perfil de carga variable. Se realiza un análisis de series temporales que da las características de rendimiento del sistema que se valida en un alimentador de prueba IEEE 123 práctico.

Battery energy storage system (BESS) is one of the effective technologies to deal with power fluctuation and intermittence resulting from grid integration of large renewable generations. In this paper, the system configuration of a China's national renewable generation demonstration project combining a large-scale BESS with wind farm and photovoltaic (PV) power station, all coupled to a power transmission system, is introduced, and the key technologies including optimal control and management as well as operational status of this BESS are presented. Additionally, the technical benefits of such a large-scale BESS in dealing with power fluctuation and intermittence issues resulting from grid connection of large-scale renewable generation, and for improvement of operation characteristics of transmission grid, are discussed with relevant case studies.
