Abstract
The adoption of natural energy sources has seen a phenomenal rise during recent decades. The reason is an improvement in their energy conversion capabilities, as well as simplification of their associated electronic control circuitry. The result at their use at a localized distributed generation level. This work is an attempt to understand and present the power quality impacts of wind and solar power generation at a localized system of distribution voltage level. The simulation is finalized in MATLAB/SIMULINK. Next a very popular solving these power quality problems namely, active power filter beside its shunt type is tested over the simulated model. Moreover, its control algorithm is implemented mathematically with P-Q theory and the results are analyzed for better power quality improvement.
Highlights
NOWADAYS active filtering of electric power becomes major technology for mitigation of harmonics in a singlephase power line generated by loads
The major cause of harmonics is the use of nonlinear devices like the Uninterruptible Power Supply (UPS) system, and rectification system, etc
The current harmonics introduced in the circuit result to be the greater voltage distortion which results in an abnormal operation of switching devices, greater power loss & temperature rise [2, 3]
Summary
NOWADAYS active filtering of electric power becomes major technology for mitigation of harmonics in a singlephase power line generated by loads. Passive filters are used to eject these current harmonics’ but a day’s research is to be done on active power filters as correlated to the passive filters It can be recognized as a better solution to cancel out the problem created by nonlinear loads [6, 7]. The microgrid advantages are discussed in [13] Their difference between microgrids & the general energy resources are defined as such as the microgrid is installed normally near to the consumer load; they have a smaller capacity as compared to the conventional grid [14,15,16]. A shunt active power filter with hysteresis control using clerk transformation is implemented to overcome harmonic distortion in a small scale wind power (DG).
