Power quality monitors (PQM) are required to be installed in a power supply network in order to assess power quality (PQ) disturbances such as voltage sags. However, with few PQMs installation, it is difficult to pinpoint the exact location of voltage sag. This paper proposes a new method for identifying the voltage sag source location by using the artificial neural network (ANN). Radial basis ...

The global electrical energy consumption is steadily rising and consequently there is a demand to increase the power generation capacity. A significant percentage of the required capacity increase can be based on renewable energy sources.The integration of Distributed Generations into grid has a great importance in improving system reliability. The power generation with renewable energy sources...

Detection of flicker sources is the first step to mitigate the effect of flicker in power system. In this paper, in order to reduce the number of measurement devices, instantaneous voltages are estimated by using state estimation methods and then root mean square of the voltages and currents variation are detected and then sign of flicker powers is obtained in selected branches. By comparing th...

A multi-agent system (MAS) is currently under development at the Center for Advanced Power Systems (CAPS) at Florida State University. CAPS is attempting reconfigure the shipboard power system without human intervention and without centralized scheduling and planning. CAPS has had success with radial plants. The CAPS solution is to use an agent to represent and exert high-level control on each ...

A substantial quantity of real power loss is accounted for the distribution system due to its radial nature. Efficient and secure operation a system, it necessary minimize active system’s voltage stability index (VSI). Power VSI in can be minimized with optimal integration distributed genera

abstract: regarding the growing use of distributed generation resources, optimal design of these units is necessary in the power system especially in the distribution network. in this paper, cuckoo optimization algorithm with multiple purposes was used to determine optimal location and size of distributed generation resources. the investigated purposes include reducing line losses, reducing med...

In the electrical distribution network, reactive power compensation aims at guarantying an efficient delivery of active power to loads, releasing system capacity, reducing system losses, and improving system power factor and bus voltage profile. The achievement of these aims depends on the sizing and location of shunt capacitors (sources of reactive power). Operational, economical and quality o...
