Lightning and Surge Protection in
Photovoltaic Installations
This article discusses about the scientific background and essential assumptions to be taken into account in case of the lightning and surge protection in photovoltaic installations. The aspects of standardization are also considered. conventional low-voltage power distribution systems
(CLVPDSs) standards are used as a guide and changed also as some characteristics of PVIs are different from that of CLVPDS. This system is applied to a applied to an actual grid-connected ....etc

1.1 World Energy Situation

world energy consumption has still increased due to expected rapid increase of world population, especially in the third world and in new industrialized countries (NICs) because ever more humans also need ever more energy. Continually rapid growth is foreseen in the near future, with the world population rising from the present 6 billion to about 8 billion over the next 25 ....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

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

Abstract –
There is a trend toward increasing the performanceof power electronics converters used in photovoltaic systems.However, parameters such as reliability, efficiency, andcomplexity might be in conflict. In this paper, the design of asimple DC/DC interleaved boost converter is assessed. It takesadvantage of state-of-the-art power devices that have fastswitching times. It is shown that requirements of low complexity,high reliability, and high efficiency can be satisfied, withoutresorting to switching aids, provided that the dev ....etc
