The dynamic response of power grids to small events or persistent stochastic disturbances influences their stable operation. Low-frequency inter-area oscillations are particular concern due insufficient damping. This paper studies the effect operating point on linear time-invariant dynamics networks. A pertinent metric based frequency grid is proposed quantify system’s stability against oscilla...

We consider a distributed optimal power flow formulated as an optimization problem that maximizes nondifferentiable concave function. Solving such by the existing algorithms can lead to data privacy issues because solution information exchanged within be utilized adversary infer data. To preserve privacy, in this paper we propose differentially private projected subgradient (DP-PS) algorithm in...

Abstract Optimal power flow (OPF) plays an important role in the secure and economical operation of distribution network. This paper proposes a novel generalized linear‐constrained optimal (GLOPF) model for both radial mesh networks, which iteratively approaches solution to original OPF problem. The first‐order Taylor series approximation method is applied linearize non‐linear non‐convex constr...
