The Sensitivity of the Model of the Process Making the Optimal Decision for Electric Power Systems in Relative Units

Abstract

The necessity of functioning of the automatic systems of control of the condition of the electric power system (EPS) with consideration of sensitivity is presented. It is advisable to carry out optimal control of the system conditions by introducing control parameters into the optimality (insensitivity) area. The permissible range of deviation of the control parameters their optimal values is defined by the solution of the direct and indirect sensitivity tasks. The direct and indirect sensitivity tasks can and should be solved in relative units using similarity theory methods. It is shown that in this case the limits of the permissible optimality range are determined analytically. Comparing the allowable values of the optimality of individual control parameters, it is possible to rank them and set the appropriate order and intensity of their actions. This makes it possible to compensate for disturbances in the EPS in the most rational way with the least amount of optimizing influences.
