Harmonic resonance is one of an important aspect being considered in a large network such as a wind power plant (WPP). This paper analyses several factors that affect resonance characteristic in a WPP and possible mitigation measures. The first part of the paper provides an analysis of resonances in WPP. Two methods of identifying resonances are performed which are a common impedance scan metho...
With the widespread use of harmonic generating devices, the control of harmonic currents to maintain a high level of power quality is becoming increasingly important. An effective way for harmonic suppression is the harmonic compensation by using active power filter. This paper presents a comprehensive survey of active power filter (APF) control strategies put forward recently. It is aimed at p...

With the rapid developments and use of non linear loads, the controlling over the harmonic current to get and maintain power quality is becoming more important. Active power filters has been used to compensate the harmonic pollution in our power system. This paper presents a efficient model to compensate the current harmonics using the inverter based Shunt Active Power Filter, Passive Power Fil...
---------------------------------------------------------------------***--------------------------------------------------------------------Abstract This paper presents two different control strategies applied to Unified Power Quality Conditioner (UPQC) to improve power quality in a three-phase, four-wire distribution system. The two control techniques are Unit Vector Template Generation (UVTG)...
Increasing application of non-linear loads cause power quality issues in power system. Even though the distributed generation helps to meet the increase in power demand, they enhance the power quality problem of grid. They need power electronic interface and produce fluctuating power output hence give rise to voltage fluctuations, voltage sags, swells, harmonic distortion etc. This paper discus...
The proposed system presents power-control strategies of a grid-connected hybrid generation system with versatile power transfer. This hybrid system allows maximum utilization of freely available renewable energy sources like wind and photovoltaic energies. For this, an adaptive MPPT algorithm along with standard perturbs and observes method will be used for the system. Also, this configuration...
With the development of modern industrial technology a large number of non-linear loads are used in power system, which causes harmonic distortion in the power system. At the same time the power quality and safe operation becomes inferior. Therefore mitigation of harmonics is very necessary under the situation. This paper presents the design of two passive filters to reduce the current harmonic...
