Power Quality Solutions for Industrial Customers

Indices for Assessing and Measuring Short and Sustained Interruption to Quantify Power System Performance

This paper presents the main results of a benchmarking survey for Northern Power System in Vietnam to measure the Power Quality and Reliability in regard to short and long-term interruption. The survey was conducted in 28 provinces and cities divided into four groups to compare: mountainous vs. delta areas and industrial vs. agricultural areas. The evaluation of power quality is based on reliab...

Power Quality Issues, Impacts, and Mitigation for Industrial Customers

Impact of Service on Customers’ Demand and Members’ Profit in Supply Chain

This paper investigates the impact of provided service by the retailers and manufacturers on customers’ demand and members’ profit in a supply chain. It focuses on a supply chain structure with one manufacturer and a common retailer. The demand of customers depends on retailer price and service level. A game-theoretic framework is applied to obtain the equilibrium solutions for each entity in s...

A Combined Metaheuristic Algorithm for the Vehicle Routing Problem and its Open Version

Abstract: The Open Vehicle Routing Problem (OVRP) is one of the most important extensions of the vehicle routing problem (VRP) that has many applications in industrial and service. In the VRP, a set of customers with a specified demand of goods are given and a depot where a fleet of identical capacitated vehicles is located. We are also given the ‘‘traveling costs’’ between the depot and all th...

Characteristics Analysis of Voltage Sag in Distribution System using RMS Voltage Method

Voltage sags caused by the short-circuit faults in transmission and distribution lines have become one of the most important power quality problems facing industrial customers and utilities. Voltage sags are normally described by characteristics of both magnitude and duration, but phaseangle jump should be taken into account in identifying sag phenomena and finding their solutions. In this pape...
