Long-Term Voltage Stability Assessment of an Integrated Transmission Distribution System

open access: yes, 2017
Long-term voltage stability assessment (VSA) of independent transmission (T-VSA) and distribution (D-VSA)systems have been studied since long to estimate load margins. However, their impacts on each other have been neglected due to simplified assumptions

Loadability increase in radial transmission lines through reactive power injection

open access: yes2017 6th International Conference on Clean Electrical Power (ICCEP), 2017
This paper investigates the loadability increase that can be obtained in radial transmission lines by means of a synchronous condenser connected at the receiving end of the line. In this configuration, the reactive power reserve at the receiving node can be used (at least in the best part) to control the reactive power flow in the radial line. This way,

Critical analysis of line loadability constraints

open access: yesInternational Transactions on Electrical Energy Systems, 2018
This paper develops a critical analysis of the constraints that influence the loadability curves of overhead transmission lines (OHLs). The constraints considered are: conductor thermal limit, allowed voltage drop (or voltage quality limit), steady-state (or angle) stability margin, voltage stability margin and Joule losses limit.

Nonlinear finite element analysis of reinforced concrete beams strengthened with textile fine grained mortar [PDF]

open access: yes, 2020
Nowadays, there was an increasing need of repairing and upgrading the reinforced concrete (RC) structure due to the deterioration of the structure. The fibre reinforced polymer (FRP) was commonly used for structural retrofitting purposes.

Branch Flow Model: Relaxations and Convexification—Part II [PDF]

open access: yes, 2013
We propose a branch flow model for the analysis and optimization of mesh as well as radial networks. The model leads to a new approach to solving optimal power flow (OPF) that consists of two relaxation steps.

Optimal Investment on Series FACTS Devices Considering Contingencies

open access: yes, 2016
Series FACTS devices are capable of relieving congestion and reducing generation costs in the power system. This paper proposes a planning model to optimally allocate TCSCs in the transmission network considering the base case and $N-1$ contingencies. We
