Power systems around the world require performing various tasks at the same time. The necessity to generate electricity at low cost, with less or null pollution and the cost increase of petroleum, put power utilities on a large and permanent stress. Renewable energy sources like wind generation is today part of a solution for various utilities problems. They are in first place concerning low pollution and the combustible has null cost, but have unfortunately the big problem of being an unpredictable energy source. Especially in the case of wind for short periods it is difficult to assure its generation. Power systems operator cannot take into account wind farms in operational planning stage. In this sense, this paper discusses the conditions for wind energy to be able of taking part of the power system spinning reserve and makes a proposal to include wind farms in spinning reserve with the aid of energy storage systems.
