The adequacy analysis system of generation capacity in electricity market could be used to analyze the level of the generation capacity adequacy in electricity market
and provide the support to power system operation and investment. Based on the analysis of several typical keepinggenerationcapacityadequacy mechanisms in the world
the main factors
functions and indexes are analyzed which effect the generation capacity adequacy
and the two new indexes are proposed which consider the economic objectives: one is value of short adequacy and the other is benefit of adequacy. Furthermore
the system structure and analysis flow chart of adequacy analysis subsystem of generation capacity in electricity market are built
and this analysis subsystem has flexible configuration and strong adaptability to meet the perpetual development demand of electricity market.
