|Title:||Maximizing firm wind connection to security constrained transmission networks||Authors:||Burke, Daniel J.

The statistical interdependency of geographically separate wind sites and the partially-dispatchable nature of wind power require a collective analysis of all potential wind farms over an extended time-frame in any optimized transmission planning study. The methodology presented in this paper separates this large optimization problem into smaller subtasks, including a year-long sequential time series hourly integer unit commitment, a linear dc load-ﬂow network model with hourly security constraints, and a linear programming optimization model to estimate the maximum ﬁrm wind energy penetration for a given network. A novel maximal vector based constraint redundancy analysis is employed to signiﬁcantly reduce the linear programming optimization dimensionality. Firm wind capacity connections are facilitated in this paper—i.e., those to which wind curtailment to manage congestion is not applicable within a typical system "planning" timeframe analysis. Each bus is allocated ﬁrm capacity on the basis of maximizing the possible ﬁrm wind energy penetration in the transmission system as a whole, while preserving traditional network security standards.||Funding Details:||Irish Research Council for Science, Engineering and Technology||Type of material:||Journal Article||Publisher:||IEEE||Copyright (published version):||2009 IEEE||Keywords:||Computational geometry;Linear programming redundancy;Power transmission;Wind energy||Subject LCSH:||Electric power production--Linear programming
