Coordination of hydro units with wind power generation based on RAROC

Liu, Yangyang; Jiang, Chuanwen; Shen, Jingshuang; Hu, Jiakai - In: Renewable Energy 80 (2015) C, pp. 783-792

Generating companies (GENCOs) with wind farms always suffer from the variations of wind power and energy prices. The coordination of wind power with hydro units is an effective way for GENCOs to enhance the ability of wind power dispatch, increase profit, and reduce risk. However, GENCOs still...

Optimal power dispatch in wind farm based on reduced blade damage and generator losses

Zhang, Jin-hua; Liu, Yong-qian; Tian, De; Yan, Jie - In: Renewable and Sustainable Energy Reviews 44 (2015) C, pp. 64-77

For large wind farms, the unit combinatorial optimization research can improve the level of wind farm operation and increase the economic efficiency of wind farms. The blades, which not only account for 20% of the total wind turbine cost, but also have much influence on the wind turbine life,...

Rolling unit commitment for systems with significant installed wind capacity

Tuohy, Aidan; Denny, Eleanor; O'Malley, Mark - 2007

As wind power penetration grows, the amount of reserve needed on the system also grows, due to the increases in the uncertainty of wind power, which grows larger as forecast horizon increases. By scheduling the system more often the amount of extra reserve to be carried to cater for wind...
