Improvement of voltage profile in Smart Grid using voltage sensitivity approach

2012 Students Conference on Engineering and Systems, 2012
The “Smart Grid” modernizes the aging power system and is characterised by two-way flow of electrical power and information within the network. Voltage stability is the prime concern of over stressed power system network. In Smart Grid, the overall voltage profile of the power network can be efficiently improved and thus avoids problems of voltage ...

Visualising the effect of DG on voltage profile in medium voltage distribution networks

2015 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC), 2015
Distributed renewable generation is increasing all over the world. The effect of Distributed Generation (DG) on system voltage profile can be examined through sensitivity studies. The sensitivity matrix depicts variations in the voltage magnitude with respect to changes in active and reactive power associated with loads and local generation at ...

Relationship between generator affinity and voltage profile improvement

2012 10th International Power & Energy Conference (IPEC), 2012
This paper demonstrates the relationship between generator affinity and voltage profile improvement. Circuit theory and the partitioned Y-admittance matrix were used to derive the generator affinity for power system networks. Results show that the lowest voltages occur at buses without generator affinity.

The interpretation of radio-influence voltage profiles

Electric Power Systems Research, 1985
Abstract A method for obtaining a radio-influence voltage (RIV) versus applied voltage profile is described. Typical results are presented and suggestions are made for their interpretation. The pass/fail levels given by various national standards and methods for applying atmospheric corrections are discussed.

Impact of Distributed Generation on Voltage Profile in Distribution System

2009 International Joint Conference on Computational Sciences and Optimization, 2009
Presence of distributed generation (DG) can represent a significant impact on the distribution networks, such as system reliability, power flow, relay protection, voltage profile and stability. It brings great challenge to the traditional distribution networks.

Reevaluation of hydropathy profiles of voltage-gated ionic channels

Experientia, 1991
A reevaluation of the secondary structure of Na, Ca and K channel proteins led to the following results. Only three segments (S1, S5 and S6) of each repeat are sufficiently hydrophobic to be predicted as transmembrane helices, if a window of 19 amino acids is used.

PV reactive power injection effect on voltage profile

2015 IEEE International Conference on Electro/Information Technology (EIT), 2015
With the growing number of Distributed Generators (DGs) in power systems, demand to utilize Photovoltaic (PV) systems has also shown increase. PV systems are equipped with PV inverters in order to convert DC power to AC power. PV inverters are great sources to improve voltage profile in the utility grid using their reactive power injection feature.

Voltage profile improvement in distribution network by means of voltage regulators

2001
Poboljšanje naponskih prilika u distributivnoj mreži otoka Hvara ostvareno je pomoću regulatora napona. Padovi napona na dugačkim distributivnim vodovima hrvatskih otoka u posljednje vrijeme predstavljaju veliki pogonski problem. U radu se prikazuje teorijski i praktični pristup rješenju navedenog problema.
