A self-tuning optimised unscented Kalman filter for voltage flicker and harmonic estimation
This paper presents a novel technique for estimation of two important power quality problems like voltage flicker and harmonics in power networks using an unscented Kalman filter (UKF) algorithm. The fluctuating voltage of a power network resulting in voltage flicker is tracked for estimating its envelope, voltage magnitude, and frequency. Further, the unscented filter is used to estimate ...

Cascade failures and distributed generation in power grids
Power grids are nowadays experiencing a transformation due to the introduction of distributed generation based on renewable sources. At difference with classical distributed generation, where local power sources mitigate anomalous user consumption peaks, renewable sources introduce in the grid intrinsically erratic power inputs. By introducing a simple schematic (but realistic) model for power ...

Optimal allocation and sizing of DG and shunt capacitors using differential evolutionary algorithm
In the last few years, a number of factors have led to an increased interest in distributed generation (DG) scheme because placement of DG is the most effective method in reducing the power loss of the distribution networks to serve remote loads. Placement of shunt capacitors improves voltage profile but unable to serve remote load as it can provide only reactive power. So, combination of both ...
