Abstract: Unified Power Flow Controller (UPFC) is one of the FACTS devices which plays a crucial role in simultaneous regulating active and reactive power, improving system load, reducing congestion and cost of production. Therefore, determining the optimum location of such equipment in order to improve the performance of the network is significant. In this paper, WCA algorithm is used to locat...
in this paper, power system restoration in the presence of svc and tcsc in partial outage conditions is considered and a new method for maximum load restoration using different control variables is presented. control variables are tap of transformers, generation rescheduling and operating points of facts devices. objective function is restored load (to be maximized) and constraints are voltage ...
Wireless sensor network a powerful network contains many wireless sensors with limited power resource, data processing, and transmission abilities. Wireless sensor capabilities including computational capacity, radio power, and memory capabilities are much limited. Moreover, to design a hierarchy topology, in addition to energy optimization, find an optimum clusters number and best location of ...
In order to gain a deep understanding of planned maintenance, check the weaknesses of distribution network and detect unusual events, the network outage should be traced and monitored. On the other hand, the most important task of electric power distribution companies is to supply reliable and stable electricity with the minimum outage and standard voltage. This research intends to use time ser...
in recent years, significant research efforts have been devoted to the optimal planning of power systems. substation expansion planning (sep) as a sub-system of power system planning consists of finding the most economical solution with the optimal location and size of future substations and/or feeders to meet the future demand. the large number of design variables, and combination of discrete ...
Background: Diabetes mellitus is a high prevalent disease among the population, and if not controlled, it causes complications and irreparable damage to the eye and cause blindness. This study goal is to investigate the predictive power of multiple logistic regression model and the Artificial Neural Network Multi-layer Perceptron (MLP) in determining patients with and without diabetic...
Simultaneous routing and resource allocation has been considered in wireless networks for its performance improvement. In this paper we propose a cross-layer optimization framework for worst-case queue length minimization in some type of FDMA based wireless networks, in which the the data routing and the power allocation problem are jointly optimized with Fuzzy distributed H∞ control strategy ....
One of the most important objectives of smart distribution networks (SDNs) is to achieve a secure and reliable network. This can be realized by optimal operation in the presence of active power sources such as the distributed generations (DGs), reactive power sources such as switched capacitor bank (SCB), active loads such as the demand response program (DRP), and various network management str...

Recently, increasing of non-linear loads in the power distribution network has been increased harmonics in these networks. The harmonics problems get worse and complicated by installation of power factor correction capacitors and filters. But the Distributed Generations (DGs) interface inverters with properly control can help to improve power quality, harmonic compensation and voltage unbalance...
