Correlates of HIV-1 genital shedding in Tanzanian women. [PDF]

, 2011
BACKGROUND: Understanding the correlates of HIV shedding is important to inform strategies to reduce HIV infectiousness. We examined correlates of genital HIV-1 RNA in women who were seropositive for both herpes simplex virus (HSV)-2 and HIV-1 and who ...

Steady state load shedding to mitigate blackout in power systems using an improved harmony search algorithm

Ain Shams Engineering Journal, 2015
Generation contingencies in a power system lead to under-frequency and low voltages owing to active and reactive power deficiencies. Load shedding is considered as a last alternative to avoid the cascaded tripping and blackout in power systems during ...

Optimal Load Shedding for Maximizing Satisfaction in an Islanded Microgrid

Energies, 2017
A microgrid (MG) is a discrete energy system that can operate either in parallel with or independently from a main power grid. It is designed to enhance reliability, carbon emission reduction, diversification of energy sources, and cost reduction. When a

Optimal Under-Frequency Load Shedding Setting at Altai-Uliastai Regional Power System, Mongolia

Energies, 2020
The Altai-Uliastai regional power system (AURPS) is a regional power system radially interconnected to the power system of Mongolia. The 110 kV interconnection is exceptionally long and susceptible to frequent trips because of weather conditions.

The use of dynamic programming and golden section search for the optimal load‐shedding strategy of HEMS participating in demand response program

The Journal of Engineering, 2021
This paper presents the optimal load‐shedding strategy of home energy management systems (HEMSs). The HEMS uses the dynamic programming (DP) method to plan the day ahead, schedule, and connects to smart plugs to perform load‐shedding.

GSO based optimization of steady state load shedding in power systems to mitigate blackout during generation contingencies

Ain Shams Engineering Journal, 2015
Load shedding is considered as a last alternative to avoid the cascaded tripping and blackout in power systems during generation contingencies. It is essential to optimize the amount of load to be shed in order to prevent excessive load shedding.

A Binary Archimedes Optimization Algorithm and Weighted Sum Method for UFLS in Islanded Distribution Systems Considering the Stability Index and Load Priority

Energies, 2023
This study proposes an under-frequency load-shedding (UFLS) scheme based on a binary Archimedes Optimization Algorithm (BAOA) and the Weighted Sum Method (WSM) to maintain the stability of an islanded distribution system. These methods consider stability

Optimal Load Shedding Scheme Considering the Dynamic Frequency Response

Engineering Proceedings
A power system is never in a steady state due to continuous load variations, disturbances, maneuvers, and the operation of protection systems. A generation deficit causes a frequency drop in the system that must be controlled. If this frequency deviation
