This paper presents a method to assess the impact on system reliability of wind integration, considering coordinated operation with cascade hydropower. The seasonal characteristics of river flows and correlation amongst different wind farms are considered. Time sequential Monte Carlo simulation and Latin Hypercube Sampling techniques are used to preserve the characteristics of the time series of the...
This paper proposes an Approximate Dynamic Programming (ADP) based approach to evaluate the effective load carrying capability (ELCC) of high penetration renewable resources by solving the long-term security-constrained unit commitment (SCUC) problem with various uncertainties related to solar radiation, wind speed, and load level. Compared with traditional approaches, the proposed approach can assist...
To accommodate the increasing wind energy with stochastic nature becomes a major issue on power system reliability. This paper proposes a methodology to characterize the spatiotemporal correlation of multiple wind farms. First, a hierarchical clustering method based on self-organizing maps is adopted to categorize the similar output patterns of several wind farms into joint states. Then the hidden...
