A new reliability assessment method for distribution system with distributed generations (DGs) is proposed in this paper, aiming to quantitatively analyze the undesired impact caused by passive islanding detection failure. Firstly, the paper analyzes the impacts of DG interconnection on auto-reclosing operation and system reliability due to failure of anti-islanding detection when a transient or permanent...
We develop a large-scale service information system integrating market analysis, customer relationship management (CRM), and distribution service optimization. The system is based on geographical information systems (GIS), and the goals include reducing the distribution cost, increasing the efficiency, satisfying customer demand, and improving service quality. We discuss in detail the design of the...
Numerical simulations are used to investigate the frequency splitting phenomena of a symmetrical 2-coil wireless power transfer (WPT) system working under seawater and fresh water. It is found that a V-type frequency splitting pattern exists in the WPT system under seawater and fresh water, and also frequency shift is observed in the underwater WPT system in overcoupled regime, and no frequency shift...
Thyristor controlled transformer (TCT) is a kind of static VAR compensator (SVC). It is mainly used to solve the power quality (PQ) problems of low power factor (PF) and three-phase unbalance. However, it pollutes the power system by producing harmonic currents during normal operation. This paper proposed a multi-objective optimal control strategy to improve the comprehensive PQ. Firstly, the total...
In this paper, we present an algorithm using Rapidly-exploring Random Trees (RRTs) to generate suboptimal paths for unmanned air vehicles (UAVs) in real time, given a starting location and a goal configuration in the presence of both static and pop-up obstacles. Generating near optimal paths in obstacle rich environments within a given short time window is a challenging task. Hence we first generate...
