Where the wind blows

Role of Energy Storage with Renewable Electricity Generation

“…Utilities in the United States have expressed concern about their systems "bottoming out" due to the minimum generation requirements during overnight hours, and being unable to accommodate more variable generation during these periods. Minimum generation constraints (and resulting wind curtailment) are already a real occurrence in the Danish power system, which has a large installed base of wind generation (Ackermann et al 2009). Due to its reliance on combined heat and power electricity plants for district heating, the Danish system needs to keep many of its power plants running for heat.…”

Current methods and advances in forecasting of wind power generation

“…Danish system operator has had similar results [56]. The RMSE is usually 10% of installed capacity for effects are felt more acutely than on land as weather fronts pass over the wind farm [66].…”

Allocation of wind capacity subject to long term voltage stability constraints

“…Active and reactive power dispatch of generator (g ∈ G) P T HE trend of wind capacity integration in power systems indicates a gradual move towards high penetrations of wind realized in terms of both energy production and instantaneous generation [1], [2]. Implications of such a move in liberalized energy markets include displacement of active power generated by conventional generation units, accompanied by a reduction of reactive power sources available.…”
