Solar power (photovoltaic) systems


INTRODUCTION

1.1 BACKGROUND OF THE PROJECT
The consumption of the energy is directly proportional to the progress of the mankind. With ever growing population, improvement in the living standard of the humanity, industrialization of the developing countries, the demand for energy increases day by day.
The primary source of energy is fossil fuel, though results environmental degradation caused by their widespread use, particularly gl ....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 that 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 consist ....etc

photovoltaic cell or photoelectric cell



The solar cell works in three steps:

1. Photons in sunlight hit the solar panel and are absorbed by semiconducting materials, such as silicon.
2. Electrons (negatively charged) are knocked loose from their atoms, causing an electric potential difference. Current starts flowing through the material to cancel the potential and this electricity is captured. Due to the special composition of solar cells, the electrons are only allowed to move ....etc
