Abstract: Renewable energy is an effective and clean source of supplying electrical loads especially in remote and rural areas. In this paper we discuss offshore wind and tidal in-stream energy as they rely on similar technologies for generating electricity at offshore sites. In particular, we survey the impacts of offshore wind and tidal current integration into the grid, various types of generators and their dynamic modeling, fault ride-through techniques used to improve generator and grid integration performance, the aggregated wind turbines modeling and finally put the light on the stability and control prob-lems.

Abstract: Energy is one of the issues that is causing the most controversy as fossil fuels are the greatest pollutants and the greatest contributors to the greenhouse effect .The increasing importance of environmental concern, fuel savings and unavailability of power has led to the renewal of interest in renewable energies. It therefore stands to reason that developing countries whose energy consumption rate is increasing at a very fast rate should be investigating new energy systems based on renewable energies that do not pollute and which are inexhaustible such as the Solar system. In this paper a simple, reliable and effective solar panel charging system has been introduced consisting of a solar panel of desired size and shape. This solar panel is integrated with an embedded system ( which contains three modules i.e. dc to ac converter, microcontroller/compiler module and charging output and a battery system).This embedded system regulates the electricity produced (after being converted to ac from dc) between the storage battery and charging output with the help of microcontroller which is programmed to combat the situations in presence and in absence of input supply and able to supply stored energy at night or in unavailability of solar source.

Abstract: This paper presents the analysis & development of hybrid Manual and Solar PV Based Power Generation System as there is a requirement to supply the rural areas of India and other developing countries with reliable electricity. Most of the rural areas won’t have access to reliable electrical power even in the next ten years. Therefore alternate means of generating electrical energy will have to be utilized at local level. One such alternative is to produce electrical energy using hybrid systems utilizing manpower and solar energy. Local institutions like Panchayats might play an important role in the implementation, operation and maintenance of the proposed power generation system. The unregulated voltage generated by the proposed power generation system has been regulated with the help of electronic circuits.

Abstract: In this paper we interested to the study the necessary of Facts to increase the transient stability on the presence of faults and the integration of new renewable source, like wind energy, these lasts make the electrical grid operate in a new conditions, the STATCOM is one of the important Facts element, It provides the desired reactive-power generation and absorption entirely by means of electronic processing of the voltage and current waveforms in a voltage source converter (VSC). This function is identical to the synchronous condenser with rotating mass. In present work we propose a transient stability improvement using STATCOM under faults, in the first time we study the transient stability with and without STATCOM for clearly his advantages. In the second time we know the relation between the reactive power injecting by a STATCOM and the critical clearing time, some simulation results are given, commented and discussed.
