| This paper is devoted to the problems of nd-ing the power ow feasibility, saddle node and Hopf bifur-cation boundaries in the space of power system parameters. The rst part contains a review of the existing relevant approaches including not so well-known contributions from Russia. The second part presents a new robust method for nding the power system(More)
|A new approach to stabilize power system transient processes is presented. It uses the idea that left shifts of the dominant state matrix eigenvalues, computed along the integral trajectory, will provide better damping of the resulting transient processes. Those shifts are made by varying the power system controllable parameters in the direction of maximal(More)
The variability and non-dispatchable nature of wind and solar energy production presents substantial challenges for maintaining system balance. Depending on the economical considerations, energy storage can be a viable solution to balance energy production against its consumption. This paper proposes to use discrete Fourier transform (DFT) to decompose the(More)
| The paper presents a novel approach to reveal loads having the biggest impact on damping of small-disturbed oscillations in power systems. The technique is based on a quasi-optimization procedure with the cost function reeecting shifts of selected eigenvalues along the real axis when all unknown load parameters are varied within their constraints. The(More)
| The paper is devoted to nding the most dangerous (critical) changes of parameters which put the power system on either a saddle node or Hopf bifurcation boundary. The corresponding vectors in the space of system parameters provide information about stability margins, give a measure of and locally optimal ways to improve power system security, indicate(More)
