Increasing wind capacity value in Tasmania using wind and hydro power coordination

Wind power penetration is increasing in power system in many countries. To mitigate wind power fluctuations and maximize clean energy utilization, coordinating wind and hydro power is proposed in the literature. This paper investigates the benefits of coordinating hydro generators with wind farms, from reliability point of view in Tasmania, Australia. Reliability indices are computed in generation system adequacy assessment using the state sampling Monte Carlo technique. In accordance with these indices the capacity value of Tasmania´s wind power is calculated and the impact of hydro power coordination on this value is demonstrated. The results show that using hydro units to support wind power will improve the capacity value of the wind farms regarding their wind regime and the combined capacity.
