Bus-based reliability indices and associated costs in the bulk power system
(1998)
This paper presents a methodology to evaluate the reliability and to calculate interruption costs at the load bus level in the bulk power system (Hierarchical Level II). The method is based on a nonsequential Monte Carlo ...
Distributed generation modelling for unbalanced three-phase power flow calculations in smart grids
(2011-05-31)
Distributed Generators (DG) are generally modeled as PQ or PV buses in power flow studies. But in order to integrate DG units into the distribution systems and control the reactive power injection it is necessary to know ...

Optimal allocation of distributed generators providing reactive power support ancillary service
(2011-10-05)
Problems as voltage increase at the end of a feeder, demand supply unbalance in a fault condition, power quality decline, increase of power losses, and reduction of reliability levels may occur if Distributed Generators ...
High-level multistep inverter optimization using a minimum number of power transistors
(2006)
Multilevel inverters with a large number of steps (more than 50 levels) can generate high quality voltage waveforms, good enough to be considered as suitable voltage template generators. Many levels or steps can follow a ...
Energy planning using MESSAGE: The effect of large energy blocks in the Chilean system
(IEEE, 2010)
The evolution of the Chilean energy matrix into a more sustainable system with high levels of energy sufficiency and security of supply in the long term brings with it important challenges in the way that investors and the ...

Clarke's alpha, beta and zero components: A possible approach for the conceptual design of instrumentation compatible with IEEE Std. 1459-2000
(2004-10-08)
The paper explains the conceptual design of instrumentation that measures electric quantities defined in the trial-use Std. 1459-2000. It is shown how the Instantaneous-Space-Phasor (ISP) approach, based on α, β, 0 components, ...
