A new active power corrective control algorithm based on sensitivity method

This paper proposes a new algorithm to solve the problem of active power corrective control in power systems. This algorithm is based on a swift decoupling sensitivity matrix, in which the power value of each part is denoted by a function with corresponding control sensitivity as the variable. Through this function and a defined static power transfer coefficient (SPTC), one can evaluate the control variables by minimizing this nonrestraint objective function, hence over-limit values will be removed or avoided. The least square method is utilized to get the final values of control variables. Positive results from analogue computing proves the rationality and validity of this new algorithm.
