Abstract: A large proportion of variable generation like wind and solar energy introduces a higher level of variability and uncertainty into power system operation than the traditional fossil, nuclear and hydro generation. Successful integration of these new energy resources requires that traditional market structures and associated transmission planning and market operation practices be re-examined in light of the different characteristics and requirements of these new energy sources. This article examines the underlying transmission planning structure needed to support the power market evolution, and a number of critical developments within the power market with respect to control area size, reserve requirements, unit commitment and economic dispatch practices, needed to enable reliable system operation with increasing penetration of variable generation.

Key words: variable generation integration, wind integration, power market, transmission planning, market operation, system operation
