The main purpose of this paper is to discuss the basic understanding of active and reactive power flows in photovoltaic (PV) based distributed generation injected power system and how these power flows will influence the performance and stability of a power system. the harmonic currents injected into the utility grid may be a serious problem since they could lead to unacceptable levels of wave ...
The global electrical energy consumption is still rising and there is a steady demand to increase the power capacity. Deregulation of energy has lowered the investment in larger power plants, which means the need for new electrical power sources may be increased in the near future. In general, this paper discusses role of modern power electronics in small size wind energy and hybrid generating ...
The interest in distributed maximum power point tracking increases along with increasing deployment of photovoltaic generators and the constant pressure to reduce the cost of photovoltaic generated energy. Distributed maximum point tracking facilitates a significant boost of captured photovoltaic power. In this paper we compare different distributed maximum power point architectures, and catego...
In this paper, a maximum power point tracker method using sliding mode control for a photovoltaic (PV) system is presented. The system includes a photovoltaic array, a DC/DC converter and a DC/AC inverter connected to a load. The designed control regulates the converter output voltage and it maximizes the power generated by the photovoltaic array. To obtain it, the sliding surface used to contr...
This paper presents a comprehensive review on three basic types of multilevel inverters i.e., diode-clamped, flying-capacitor, and cascaded H-bridge multilevel inverter and their variation for photovoltaic power system. The electrical power generated form photovoltaic power system is in DC form. Hence, it is necessary to be controlled and converted to useful form. Inverter is a power electronic...
This paper focuses on power quality improvement in the distribution network using three phase shunt active power filter, where this later is connected to photovoltaic system. In the present work, a new control method has been presented to eliminate harmonic currents that is caused by nonlinear loads, and to compensate reactive power. This control method has a good accuracy and high efficiency, ...
