Harnessing energy from alternative energy source has been recorded since early history. Renewable energy is abundantly found anywhere, free of cost and has non-polluting characteristics. However, these energy sources are based on the weather condition and possess inherited intermittent nature, which hinders stable power supply. Combining multiple renewable energy resources can be a possible solution to overcome defects, which not only provides reliable power but also leads to reduction in required storage capacity. Although an oversized hybrid system satisfies the load demand, it can be unnecessarily expensive. An undersized hybrid system is economical, but may not be able to meet the load demand. The optimal sizing of the renewable energy power system depends on the mathematical model of system components. This paper summarizes the mathematical modeling of various renewable energy system particularly PV, wind, hydro and storage devices. Because of the nonlinear power characteristics, wind and PV system require special techniques to extract maximum power. Hybrid system has complex control system due to integration of two (or more) different power sources. The complexity of system increases with maximum power point tracking (MPPT) techniques employed in their subsystems. This paper also summarizes mathematical modeling of various MPPT techniques for hybrid renewable energy systems.

“…To operate a WT at its high level of efficiency, an MPPT strategy is needed [7][8][9][10][11][12][13][14]. Three main kinds of MPPT strategies of WECS can be found in the literature, the TSR, the power signal feedback (PSF), and the hill climbing searching technique (HCS) [15][16][17], where the major differentiation between each one is based on its attempt to use sensors of measuring parameters and the WT characteristics.…”

Under the trends to using renewable energy sources as alternatives to the traditional ones, it is important to contribute to the fast growing development of these sources by using powerful soft computing methods. In this context, this paper introduces a novel structure to optimize and control the energy produced from a variable speed wind turbine which is based on a squirrel cage induction generator (SCIG) and connected to the grid. The optimization strategy of the harvested power from the wind is realized by a maximum power point tracking (MPPT) algorithm based on fuzzy logic, and the control strategy of the generator is implemented by means of an internal model (IM) controller. Three IM controllers are incorporated in the vector control technique, as an alternative to the proportional integral (PI) controller, to implement the proposed optimization strategy. The MPPT in conjunction with the IM controller is proposed as an alternative to the traditional tip speed ratio (TSR) technique, to avoid any disturbance such as wind speed measurement and wind turbine (WT) characteristic uncertainties. Based on the simulation results of a six KW-WECS model in Matlab/Simulink, the presented control system topology is reliable and keeps the system operation around the desired response.

“…Furthermore, the proposed approach can be applied to any electrical alternator/generator, whether the electromagnetic torque is known. Detailing upon the control system, connection to the electrical grid, and the operation with constant speed or variable speed using power electronic converters were described in Hong;Chen;Tu (2013). Thus, only to reduce the complexity of the electromagnetic torque equation, the relation between synchronous generator torque and its angular speed is assumed as an approximated linear equation (MESQUITA et al, 2014).…”

In this work, an efficient mathematical model applied to transient behavior of Horizontal-Axis Wind Turbines (HAWT) was developed. The influence of the power drive on HAWT dynamic modelling was taken into account, in order to present an improved approach for the design of wind power systems. In all simulations, a rotor with 30 m diameter operating at 20 m/s wind velocity was used. The driveline comprises the mass-moment of inertia, electromagnetic torque, and the friction torque of whole system. To solve the nonlinear dynamic equation at each time step, 4 th order Runge-Kutta numerical method was considered, while a Newton-Raphson scheme was applied to the steady-state regime. In addition, to calculate the aerodynamic torque, the Blade Element Theory (BET) was implemented, since such a parameter is usually obtained through approximated mathematical functions, mainly those applied to large wind turbines as described in several works available in the literature. BET is a well-known method applied to design and aerodynamic analysis of wind turbines, which presents good agreement with experimental data. To conclude, the results show the rotational speed, output power and torque dependents on time, and depict good behavior when compared with Bao and Ye (2001). An application using BET was also carried out, which yielded consistent results. Keywords: Wind turbine, Dynamic behavior of HAWT, Blade Element Theory. RESUMONeste trabalho foi desenvolvido um modelo matemático eficiente aplicado ao comportamento transiente de Turbinas Eólicas de Eixo Horizontal (HAWT). Foi levado em consideração a influência da unidade de transmissão na modelagem dinâmica a fim de se obter uma abordagem melhorada para o projeto de sistemas de energia eólica. Em todas as simulações, um rotor de 30 m de diâmetro operando a 20 m/s de velocidade de vento foi utilizado. O sistema de transmissão compreende o momento de inércia, torque eletromagnético e o torque de atrito de todo o sistema. Para solucionar a equação dinâmica não linear em cada intervalo de tempo, o método de Runge-Kutta de 4 a ordem foi considerado, enquanto que o método de Newton-Raphson foi aplicado ao regime estacionário. Além disso, para calcular o torque aerodinâmico, a teoria do elemento de pá (BET) foi implementada, uma vez que o torque do rotor é frequentemente calculado através de funções matemáticas aproximadas, principalmente quando aplicados a grandes turbinas eólicas, tal como descrito em várias obras disponíveis na literatura. BET é um método bem conhecido aplicado ao projeto e análise aerodinâmica de turbinas eólicas, o qual apresenta boa concordância com dados experimentais. Para concluir, os resultados para a velocidade de rotação, potência de saída e torque dependentes do tempo mostram bom comportamento quando comparados com Bao; Ye (2001). Uma aplicação utilizando o método BET também foi realizado, o qual produziu resultados consistentes. Palavras-chave: Turbinas eólicas, comportamento dinâmico de HAWT, teoria do elemento de pá.
