Abstract:
For reducing a storage capacity of a storage battery system and an installation cost at a constant-output control type of wind power plant, a wind power generation control device sets as a planned generation power value PT: an average wind generated power value PA, when a current battery charging rate SOC of the storage battery system is within the range of the upper and lower limit values of the targeted battery charging rate range SOCT (S12); a value obtained by multiplying a positive constant greater than 1 to the said PA, when the current battery charging rate SOC is above the upper limit value of the said SOCT (S14): and a value obtained by multiplying a positive constant less than 1 to the said PA, when the current battery charging rate SOC is below the lower limit value of the said SOCT (S15).
