Recently, more and more people realize the importance of environment protection. Electric power generation systems using renewable energy sources have an advantage of no greenhouse effect gas emission. Among all the choices, wind power can offer an economic and environmentally friendly alternative to conventional methods of power supply. As a result, wind energy generation, utilization and its grid penetration in electrical grid is increasing world wide. The wind generated power is always fluctuating due to its time varying nature and causing stability problem. Inserting energy storage system into large scale wind farm to eliminate the fluctuation becomes a solution for developing large scale renewable energy system connected with grid. The topology diagram and control strategy are presented in this paper. According to the simulation result, it could be indicated that embedding energy storage system into wind power system could improve the access friendly and extend system functions. This paper shows that integrating energy storage system into wind power system will build a more reliable and flexible system for power grid.

A elevada intermitência das fontes de energia renováveis condiciona a produção de energia elétrica, que continua a depender muito dos combustíveis fósseis. Uma vez que existe complementaridade por parte das fontes de energia renováveis, a sua integração conjunta é, sem dúvida, a melhor solução para reduzir esta dependência. Aliado a este facto, poderá coexistir um sistema de armazenamento por bombagem, capaz de gerar reservas hídricas, que serão aproveitadas quando a procura exceder a oferta energética. Procedeu-se ao desenvolvimento de dois modelos: um sobre custos de turbomáquinas e outro que visa o estudo do potencial de recuperação de energia de uma solução energética híbrida com armazenamento por bombagem combinado com fonte de energia eólica. Foram estudadas diferentes combinações para estas duas fontes de energia renovável, analisando o consumo satisfeito e a energia eólica não consumida, tendo-se concluído que o excedente de energia eólica pode ser aproveitado para bombagem. The high intermittence of renewable energy sources determines the production of electricity, which remains highly dependent on fossil fuels. Since there is complementarity between renewable energy sources, their joint integration is a potential solution to reduce this dependency. Consequentially, a pumping storage system capable of generating water reserves can coexist, which will be used when demand exceeds the energy supply. Two models were developed: one based on turbomachinery costs and the other based on the potential of energy recovery of a hybrid energy solution with pump storage combined with wind energy. Different combinations were studied for these two sources, analysing the satisfied consumption and the wind energy that is not consumed, in which it was concluded that the surplus of wind energy can be used by pumped storage.

In the research work, impactness of Renewable Energy source like Wind Energy is reinforced to enhance the dynamic performance of Thermal and Hydro power plant under various operating conditions in which steam act as a major contributor for generation of electricity and rest of the generation through water. This technique is helpful in agricultural as well as islet spaces. The uneven generation of power will cause fluctuation in load followed by large disturbance in frequency of power system. To overcome this nature of fluctuations, wind energy will offer and consume instantly the true and apparent powers. The execution and it’s testing are exhausted in a convenient MATLAB/Simulink condition with the application of step load and a continuing load perturbation of 1% within the system and whose results exposed that involvement of wind energy storage unit in the hybrid Thermal Hydro power system enhance transient performance of each thermal & hydro sides.
