[ 1 ] - A Novel Method for Implementing of Time-of-use to Improve the Performance of Electric Distribution Systems: A Case Study
Increased electric energy consumption in recent years, associated economic problems, reduced reliability and increased power losses in electric networks. One of the main solutions in smart grids to overcome the mentioned problems is demand response programs. In demand response programs, operators apply time-varying tariffs to consumers, and convince them to change their consumption pattern. Amo...
[ 2 ] - Optimal Placement and Sizing of Fault Current Limiter in a Real Network: a Case Study (TECHNICAL NOTE)
In this paper, the effect of number and fault current limiter(FCL) location has been investigated in order to have maximum reduction of short circuit current level in all buses in a real network. To do so, the faulty buses were identified in terms of short circuit current level by computing short circuits on the desired network. Then, while the fault current limit was modeled, its optimal locat...
[ 3 ] - Optimal Sitting, Sizing, and Operation of Batteries and Passive Filters to Mitigate Over-voltage and Harmonic Problems in Distribution Networks with High Photovoltaic Penetration
Photovoltaic systems (PVs), despite their many advantages, may have effects such as power quality issues (voltage and harmonics increase), short-circuits level increase, protection issues, and transient stability for network. Some of these effects are due to the high PV penetration, which encounters the network with the over-voltage and harmonics problems. In this paper, the location, size and ...
