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 del ....etc

Abstract”
In this seminar a new maximum power point tracking algorithm for photovoltaic arrays is proposed. The algorithm detects the maximum power point of the PV. The computed maximum power is used as a reference value (set point) of the control system. ON/OFF power controller with hysteresis band is used to control the operation of a Buck chopper such that the PV module always operates at its maximum power computed from the MPPT algorithm. The major difference between the proposed algorithm and other techniques is t ....etc

DEVELOPMENT OF OPTIMISED CONTROL CONCEPT
FOR DECENTRALIZED PHOTOVOLTAIC HYBRID
ABSTRACT
Nowadays, decentralized photovoltaic hybrid systems have gained increasing ac-
ceptance on the distributed power supply market. However there are still some
drawbacks in their performance which mainly arise from conventional operation
control strategies. This paper presents an advanced control strategy of the supervi-
sory controller of the decentralized PV hybrid systems. The basic objectives of the
developed control concept are to achieve consi ....etc

VOLTAGE SOURCE CONVERTER TOPOLOGY FOR HVDC GRID CONNECTION OF OFFSHORE WIND FARMS
ABSTRACT
Large offshore wind farms are recently emerging as promising alternative power Sources. Long distances between offshore generation and onshore distribution grid demand new solutions for their connection to the AC network. HVDC systems based on voltage source converters (VSC) are a promising alternative to conventional AC transmission above a certain cable length. This paper p ....etc
