The capability of routing power from one phase to another, interphase flow (IPPF) control, has the potential improve systems efficiency, stability, and operation. To date, existing works on IPPF control focus unbalanced compensation using three-phase devices. An model is proposed for capturing general caused by single-phase elements. reveals that presence a quantity in line-to-line elements cau...

This work proposes an intelligent allocation of distributed generation (DG) units and shunt reactive compensators (SRC) with high penetration capacities into distribution systems for power loss mitigation using the Bald Eagle Search (BES) optimization algorithm. The causes a reduction in voltage variations enhances stability systems. SRC include capacitors (SC), Static Var Compensators (SVC), D...

In this paper we develop linear, fixed-order (i.e., fulland reduced-order) pressure rise feedback dynamic compensators for axial flow compressors. Unlike the nonlinear static controllers proposed in the literature possessing gain at all frequencies, the proposed dynamic compensators explicitly account for compressor performance versus sensor accuracy, compressor performance versus processor thr...

Under critical situation the main preoccupation of expert engineers is to assure power system security and to deliver power to the consumer within the desired index power quality. The total generation cost taken as a secondary strategy. This paper presents an efficient decomposed GA to enhance the solution of the Optimal Power Flow (OPF) with non-smooth cost function and under severe loading co...

Transmission System Operators (TSOs) are currently experiencing a voltage rise problem on their network, especially during the periods of low demands. It is costly to mitigate the excessive voltages by installing reactors or Var compensators in transmission network. Recently, an alternative method of utilising the existing parallel transformers of distribution network is proposed. It uses a tap...

On recent trends, the reactive power planning problem has received a considerable amount of attention for allocation resources, both static and dynamic such as switchable capacitors and/or reactors, well Var compensators, respectively. The significant impact on voltage profile, stability transmission loss in systems. In years, instability is recognized major threat to system operation due short...

abstract portfolio definition is the most important decision for individuals and legal persons that invest in stock. the main objective of this paper is study and determination of optimal portfolio for stock of active food industrial company in tehran stock based on value at risk (var) index. for this purpose, we used weekly static of stock of active food industrial company in tehran from bahma...

Such methods as droop method, curve shifting method and master-slave were primarily developed for voltage frequency regulation in isolated power systems with synchronous generators. In modern induction generators, regulated dump loads, energy storage devices AC/DC AC/DC/AC converters, etc. are used addition to The investigation of new configurations is closely tied further development control l...
