Real world optimal UPFC placement and its impact on reliability
TL;DR: In this paper, a GA is used to find the optimal location and the optimal UPFC settings to enhance the transmission lines overloading issue, while maintaining the same level of reliability in terms of outage costs.
Proceedings ArticleDOI
Real-time matching of local generation and demand: The use of high resolution load modeling
TL;DR: 1-minute and 1-hour resolutions data are used to evaluate load matching index of PVs and wind turbines along with storage battery and demand response solutions and demonstrate the relatively high relevance of 1-minute data resolution in case of demand response planning and also for wind turbine generations.
Proceedings ArticleDOI
A Probabilistic-Based Technique using Transient RMS Currents for Earth Fault Detection in Medium Voltage Distribution Networks
TL;DR: In this paper, a transient probabilistic-based technique for earth-fault detection in isolated and compensated neutral medium voltage networks is presented, which is based on Bayesian theorem for selecting the faulted feeder using the transient RMS fault current.
Proceedings ArticleDOI
Self-adaptive De-noising Technique based on DWT for PD Measurements and Self-healing Networks
TL;DR: An adaptive de-noising technique based on discrete wavelet transform (DWT), capable of de- noising the measured signals automatically without any human intervention is presented in this paper and proves that it is simple, effective and reliable in terms of run time which makes it more useful for online monitoring application.

A method for ground fault distance computation in unearthed medium voltage distribution network
Mohd Rafi Adzman,Matti Lehtonen +1 more
TL;DR: In this paper, a method for estimating a single phase to ground fault location in radially operated unearthed distribution network is proposed based on correlation of undamped charge transient frequency with the fault distance.
