“…The central slope is enforced to zero which avoids to call for unnecessary actuation of the DGs reactive powers for low voltage variations (25d). Finally, for the interval j, the slopes α j g of the industrial piecewise affine controller with 5 segments are bounded to keep the stability of the closed-loop system [27] (equation (25e)).…”

“…Several solutions have been investigated to be able to maintain the voltage within specified limits while avoiding network reinforcement costs [1] [3] [4]. Among these ideas, local control laws of DG reactive power (Q) as a function of their voltage (U) have been highly considered.…”

Abstract-Recent research has proved that, the local reactive power control laws considered to solve voltage stability issue might lead to voltage instability. For this reason, the current paper proposes an approach to study voltage stability of multiple distributed generators in distribution feeders. The methodology relies on the construction of an equivalent state space model of the continuous system. A simulation based on MATLAB of the proposed approach to a real medium-voltage 26 buses network with 3 distributed generators reveals unstable operating situations of the network and helps to design a set of measurement filters to ensure system stability.
