Active power control method for wind diesel system based on energy storage

Abstract

This paper presents the modeling and simulation of isolated wind diesel hybrid system (WDHS) consisting a wind turbine generator (WTG) along with a diesel generator (DG), Ni- Cd battery base energy storage source (BESS) and a dump load (DL) provides the supply to consumer load. WTG and BESS are used in the system to minimize fuel consumption, but this makes the system more complex. The consumer load and wind speed is not in our hand so in this modeling by taking the worst cases of change in consumer load and change in wind speed presents various result and stability of the system. Aim of this article that how the system becomes stable after changing in consumer load and change in wind speed.
