This paper presents the modelling of nonlinear load used in domestic and small scale industrial distribution system. Proportional integral controller is used for the current control, fuzzy based MPPT is used for the variation of power from PV due to the change in atmospheric condition. Harmonics are compensated by the virtual impedance implementation. However due to increasing implementation of multiple distributed generation in residential areas, DG grid interfaced converters are used to improve the power quality. Harmonic analysis of the distribution system is used to study the behavior of equipment connected in the non-sinusoidal system environment for designing and optimal location of filters. THD is used as harmonics index to study the effect of these nonlinear loads at utility. In depth analysis and comparison of different compensation schemes based on the virtual harmonic damping impedance concept are carried out. The effect of harmonics and the compensations are verified by the analysis and simulation by MATLAB/Simuink.Keywords

This paper proposes and experimentally validates the functionality of a smart IEC 61850 merging unit (MU) that supports self-healing and asset management functions of future power grids. The proposed MU can operate in a standalone or as an integrated element within a primary substation. The MU communicates with a supervisory control and data acquisition (SCADA) system over Ethernet and WiFi-5 GHz links. A dynamic wavelet-based windowing technique is implemented in the proposed MU to process signals and report limited situation awareness (SA) features. The SA features serve two purposes. First, they can be used by asset management functions to monitor and diagnose the equipment heath condition. Second, they can be employed by self-healing functions in order to detect and anticipate early stages of impending faults masked by high noise. This information is received by a specially designed application interface running on a PC connected through wifi wireless link. All the parameters are sensed by Arduino board built in with ADC, through the comparators and it transmit by 2.4GHz Wifi.Keywords
