A coordinated control method of voltage and reactive power for active distribution net-works based on soft open point [PDF]

, 2017
The increasing penetration of distributed generators (DGs) exacerbates the risk of voltage violations in active distribu-tion networks (ADNs). The conventional voltage regulation de-vices limited by the physical constraints are difficult to meet the ...

Day-Ahead Operation of an Urban Energy System Considering Traffic Flows and Peak Shaving

Frontiers in Energy Research, 2022
With the increasing penetration of new-type loads such as electric vehicles and hydrogen fuel vehicles in urban power grids, the peak-to-valley load difference increases sharply, and a multi-energy coordination model is desirable. This article proposes a

Linear inequalities convex transformation for optimal reactive power flow model based on MISOCP relaxations

IET Generation, Transmission & Distribution, 2018
A convex optimisation model for global optimum solution of optimal reactive power flow (ORPF) problem is proposed in this study, to solve the challenge of discrete variables of transformer taps involved in traditional ORPF models. Based on the second‐order cone programming relaxation, a set of inequalities with 0–1 variables are introduced, to ...

Polyhedral approximation in mixed-integer convex optimization

, 2017
Generalizing both mixed-integer linear optimization and convex optimization, mixed-integer convex optimization possesses broad modeling power but has seen relatively few advances in general-purpose solvers in recent years.
