The use of hydroelectric pump-storage system at large scale, MW-size systems, is already widespread around the world. Designed for large scale applications, pump-storage station can be scaled-down for small, remote residential applications. Given the cost and complexity associated with installing a substation further than 100 miles from the main transmission lines, a remote, independent and sel...

The aim of this paper is to investigate the power factor correction (PFC) of Boost Converter under an average current-mode control. Boost converter topology is used to accomplish this active power-factor correction in many discontinues/ continuous modes. The boost converter is used usually it is easy to implement and works well. In this paper comparative evaluation of different techniques for h...

In this paper grid connected boost photovoltaic micro inverter system using maximum power point tracking is presented. First the photovoltaic module is analyzed using SIMULINK software. The main aim of the Paper is the boost converter is to be used along with a Maximum Power Point Tracking control mechanism. The MPPT is responsible for extracting the maximum possible power from the photovoltaic...

In this paper, we present a new maximum power point tracking (MPPT) algorithm that can identify whether boost converter is operating in continuous conduction mode (CCM) or discontinuous (DCM). The conventional MPPT assumes the always CCM mode, even though not case. enter DCM due to factors such as inductor size, irradiance and temperature conditions, voltage step size of algorithm, PV array. pr...

This paper studies the possibilities of decomposition of the current in three-phase, three-wire systems based on the classic p-q theory. Recently, the energy crisis in the world has led to the rise in use of renewable energy sources with the advancement in power electronics technology, the solar photovoltaic energy has been recognized as an important renewable energy resource because it is clea...

Load balancing is an important issue in distributed systems. In addition, using distributed generation sources such as photovoltaic is increasing. Power electronic converters are main interfaces between the sources and the grid. In this paper, a method has been proposed to reduce the load imbalancing in distribution networks using PV Grid Interface Converter. Two DC/DC and DC/AC converters have...

This paper proposes a Advanced control scheme for a stand-alone PV application. A two power stage approach has been used that consists of a front end high gain DC-DC converter followed by a three phase H-bridge inverter. A general reactive load has been considered. The control scheme uses abc to dq reference frame transformation. The active power demand is controlled by regulating the dc link v...

Abstract:Today, one of the important issues of power quality (PQ) in power systems is the current harmonics. Increasing expansion of nonlinear loads at different parts of the electric network makes harmonic distortion flow through the network. This causes the network to have background voltage and current harmonic distortion and even affect on the PQ of linear load performance. Therefore, it is...
