Abstract This postdoctoral project is related to the dynamic and steady-state analysis of power systems with renewable energy and battery storage systems. The use of battery storage in the electric systems is a well-kwon application, however is limited to UPS (Uninterruptible power supply). The UPS guarantees the fast emergency supply to the loads when the grid is disconnected during a contingence, voltage sags or fast grid interruption.The technology development of the last decade has resulted in new types of batteries, creating new applications and different possibilities of use. Some of these possibilities will be discussed further in this project proposal. The use of the battery energy storage systems are still in the infancy considering the possible applications with renewable energies, including wind turbines. The company GE has already developed one version of this possible combination (GE's 2.5-120) clamming more efficiency and also more injected power. There are different battery technologies and necessities in the integration of intermittent wind power into the power systems. The development of dynamic nonlinear three-phase models of battery systems and wind turbines, including the control systems, the mechanical systems and the aerodynamics will be performed using the SimPowerSystems (a toolbox of the Matlab/Simulink platform). A complex wind model is necessary to represent fast variations in wind speed in order to simulate more realistic situations of the injected electric power. In addition, will be developed methodologies and studies in steady-state to analyze the impact of battery energy storage systems in the enlargement of wind power penetration in power systems. The project seeks to analyze and to propose a methodology to verify the effective use of storage battery systems in wind power applications. | |
