Risk Reserve Constrained Economic Dispatch Model with Wind Power Penetration

Zhou, Wei; Sun, Hui; Peng, Yu - In: Energies 3 (2010) 12, pp. 1880-1894

This paper develops a modified economic dispatch (ED) optimization model with wind power penetration. Due to the uncertain nature of wind speed, both overestimation and underestimation of the available wind power are compensated using the up and down spinning reserves. In order to determine both...
