Thus, the evaluation indicator system and comprehensive evaluation method of wind farm power generation performance, including the influence of wind energy resource differences, are proposed in this paper to address the problems above, to which some new concepts such. Thus, the evaluation indicator system and comprehensive evaluation method of wind farm power generation performance, including the influence of wind energy resource differences, are proposed in this paper to address the problems above, to which some new concepts such. A number of indicators derived from atmospheric variables can be useful as proxies of energy production/demand. Currently, this package provides two indicators for wind power generation: WindPowerDensity - Wind power that is available for extraction from the wind flow, per square meter of swept. Wind power generation fluctuates because of continually changing wind speeds. Accurate forecasting models are required for successfully integrating such fluctuating generation into the grid and market. Wind Power generation is available as two components: Wind Power capacity factor (CFR), defined as the ratio of actual generation over installed capacity, is calculated at grid point level, considering one single wind.
