Stability Enhancement of Wind Power System: using Energy Capacitor System - Softcover

Inhaltsangabe

This work presents an energy capacitor system (ECS) which combines of electric double layer capacitor (EDLC) known as super capacitor and power electronic devices for wind power application with its detailed modeling and control strategy which can supply smooth electrical power to the power grid and makes the system better reliable. Due to the intermittent and stochastic nature of the wind, the generated power from the wind fluctuates randomly. For the future energy systems with high penetration of wind power generation, it is essential to emphasis the research on wind power smoothing. The objective of control system is to select a line power reference level and to follow the reference level by absorbing or providing active power to or from ECS to smooth output power fluctuation and to keep the wind farm terminal voltage at a desired reference level by supplying necessary reactive power. The performance of the proposed system is investigated by simulation analysis in which simulations are performed by using PSCAD/EMTDC.
