The article presents the results of modification of the dynamic programming method to solve of  the knapsack problem in determining the active composition of a wind power station with regard to the effectiveness of each wind turbine and the use of  an accumulating element in the structure of the system under investigation.

The comparative analysis of the modification of dynamic programming method for the determination of the active composition of a wind power station using the classical method of dynamic programming and that at an increased load by the experimentally founded percentage has defined advantages and disadvantages of using each of the methods under investigation.

It has been found that the modification of the dynamic programming method for solving the knapsack problem shows the possibility of improving the conditions of equality of generation and consumption of electricity compared to the classical method of dynamic programming to the standard deviation of 0,046%, and makes it possible for this method to be applied to determine the active composition of a wind power station.
