An economic-environmental energy management system design for MT-HVDC networks via a semi-definite programming approximation with robust analysis

Ain Shams Engineering Journal
This research deals with the economic-environmental dispatch problem (EEDP) in multi-terminal high-voltage direct-current (MT-HVDC) systems by proposing a convex approximation based on semi-definite programming (SDP).

Secrecy Transmission for Self-Energy Recycling Untrusted Relay Networks With Imperfect Channel State Information

IEEE Access, 2019
For the self-energy recycling (SER) untrusted relay network, a two-phase destination-based jamming (DBJ) protocol is proposed, in which the destination transmits the jamming signal to reduce the received SNR of the untrusted relay node in the first phase

Sequential Convex Programming Methods for A Class of Structured Nonlinear Programming [PDF]

, 2016
In this paper we study a broad class of structured nonlinear programming (SNLP) problems. In particular, we first establish the first-order optimality conditions for them.

A convex OPF approximation for selecting the best candidate nodes for optimal location of power sources on DC resistive networks

Engineering Science and Technology, an International Journal, 2020
This paper proposes a convex approximation approach for solving the optimal power flow (OPF) problem in direct current (DC) networks with constant power loads by using a sequential quadratic programming approach.

Matrix convex functions with applications to weighted centers for semidefinite programming [PDF]

In this paper, we develop various calculus rules for general smooth matrix-valued functions and for the class of matrix convex (or concave) functions first introduced by Loewner and Kraus in 1930s.

Disciplined Convex Programming [PDF]

, 2006
A new methodology for constructing convex optimization models called disciplined convex programming is introduced. The methodology enforces a set of conventions upon the models constructed, in turn allowing much of the work required to analyze and solve the models to be automated.

Conditional Risk Mappings [PDF]

We introduce an axiomatic definition of a conditional convex risk mapping. By employing the techniques of conjugate duality we derive properties of conditional risk mappings.
