ppt about power management strategies for grid connected pv fc system

Abstract

This paper presents a method to operate a grid connected hybrid system. The hybrid system composed of a Photovoltaic (PV) array and a Proton exchange membrane fuel cell (PEMFC) is considered. The PV array normally uses a maximum power point tracking (MPPT) technique to continuously deliver the highest power to the load when variations in irradiation and temperature occur, which make it become an uncontrollable source. In coordination with PEMFC, the hybrid system o ....etc

Abstract-
A pulse skipping control strategy is proposed to improve efficiency of grid-tied inverters at light loads. To maximize the efficiency of pulse skipping operation mode, three key parameters are identified and optimized based on a loss model, which is developed to find the maximal efficiency points using a three-dimensional search technique. A 200W prototype inverter was setup to verify the proposed control strategy. The experimental results show that the proposed pulse skipping control strategy greatly impr ....etc

Single-Phase Seven-Level Grid-Connected Inverter
for Photovoltaic System



I. INTRODUCTION
THE ever-increasing energy consumption, fossil fuels
soaring costs and exhaustible nature, and worsening
global environment have created a booming interest in renewable
energy generation systems, one of which is photovoltaic.
Such a system generates electricity by converting the Sun s energy
directly into electricity. Photovoltaic-generated energy can
be delivered to power system n ....etc

Abstract
When no transformer is used in a grid-connected photovoltaic
(PV) system, a galvanic connection between the grid and
the PV array exists. In these conditions, dangerous leakage currents
(common-mode currents) can appear through the stray capacitance
between the PV array and the ground. In order to avoid
these leakage currents, different inverter topologies that generate
no varying common-mode voltages, such as the half-bridge and
the bipolar pulsewidth modulation (PWM) full-bridge topologies,
have been proposed. The nee ....etc
