A study of factors inﬂuencing this associated wind energy curtailment is, therefore, of timely importance. In this paper, the wind curtailment estimation effects of natural inter-yearly wind proﬁle variability, system demand-proﬁle/fuel-price parameter uncertainty, and minimum system inertial constraints are studied in detail. Results indicate that curtailment estimation error can be reduced by appropriate wind data year-length and sampling-rate choice, though a pragmatic consideration of system parameter uncertainty should be maintained. Congestion-related wind energy curtailment risk due to such parameter uncertainty exhibits appreciable interlocational dependency, suggesting there may be scope for effective curtailment risk management. The coincidence of wind energy curtailment estimated due to network thermal congestion and system wide inertial-stability issues also has commercial significance for systems with very high wind energy penetration targets, suggesting there may be appreciable interaction between different sources of curtailment in reality||Funding Details:||Science Foundation Ireland||Type of material:||Journal Article||Publisher:||IEEE||Copyright (published version):||2011 IEEE||Keywords:||Power generation dispatch;Power system economics;Power transmission;Uncertainty;Wind energy||Subject LCSH:||Electric power systems--Economic aspects
