In present day restructured power systems, increased transactions often lead to the situations where the system no longer remains in secure operating condition. To overcome such undesirable situation the Flexible AC transmission system (FACTS) controllers can be placed in a power system, which are able to provide fast and flexible control of voltage magnitude, active and reactive powers and to ...

Gap junctions are intercellular channels that link the cytoplasm of neighboring cells. Because a gap junction channel is composed of two connexons docking head-to-head with each other, the channel voltage-gating profile is symmetrical for homotypic channels made of two identical connexons (hemichannels) and asymmetric for the heterotypic channels made of two different connexons (i.e., different...

This paper proposes an Imperialist Competitive Algorithm (ICA) for optimal multiple distributed generations (DGs) placement and sizing in a distribution system. The objective is to minimize the total real power losses and improve the voltage profile within real and reactive power generation and voltage limits. Three types of DG are considered and the ICA is used to find the better sizes and loc...

Recently, LVDC (Low Voltage Direct Current) distribution system have been evolving into one of the most interesting topics in the field of distribution system due to its advantages in terms of power quality, reliability and power conversation loss reduction. Voltage control in LVDC distribution system is becoming important to improve the power quality and system reliable, it can keep voltage pr...

This paper presents voltage control scheme by using directly voltage-controlled distributedenergy resource units (VC-DERs) of an islanded microgrid to provide overcurrent,voltage sag and harmonics protection. The overcurrent protection scheme detects the fault, limits the output current magnitude of the DER unit, and restores the microgrid to its normal operatingconditions subsequent to fault c...

Recent years, embedded generators have been increasingly installed in distribution system in many parts of the world. Depending on their operating characteristics and locations, embedded generators could significantly affect the voltage profile, network losses and fault level in a distribution system. This paper presents a new technique for determining optimal allocation and sizing of embedded ...

Current microprocessors are complex systems with multiple cores and non-trivial architectures, employing millions of sub-100nm transistors designed for extreme power, speed, and reliability constraints.1 An efficient control scheme for dynamic power, reliability, error detection-correction, workload scheduling, and thermal management is required. However, neuromorphic architectures are currentl...

In any power system network, voltage stability is a major concern for secure operations. But recently due to their stressed operations for increasing loading, voltage instability and voltage collapse are evitable, which is a major threat to power system. So it is very important to maintain voltage profile within the limits for overloading conditions also, which can possible through optimal plac...
