“…Algumas dessas estratégias têm desvantagens como o controlador PI devido ao fato que seus ganhos são calculados para um ponto fixo de operação. O trabalho [19] é uma alternativa que aborda o PI com emprego do anti-windup porém utilizando uma topologia diferente do conversor backto-back o qual é usualmente empregado. Foi observado que quando comparado ao tradicional back-to-back, usado em aplicações eólicas com geradores gaiola de esquilo, a topologia apresentada emprega apenas uma fração da potência do inversor para o controle da tensão no terminal da máquina.…”

Resumo-Este artigo propõe um controlador preditivo baseado em um modelo aplicado no gerador de indução de gaiola de esquilo usando um controle direto de torque. O sistema é composto por um gerador, que é conectado à rede de energia através de um conversor back-to-back. O conversor conectado à rede emprega a técnica de controle preditivo direto de potência. Sendo assim, é possível controlar a potência ativa e reativa que será injetada na rede. O controlador preditivo não necessita de sintonia e possui menor complexidade de implementação. Em ambos os casos, o controlador preditivo seleciona o vetor ótimo a ser aplicado no conversor do gerador ou no conversor da rede elétrica através da minimização de uma função custo, de forma que as referências sejam atendidas. Os resultados experimentais mostrarão o desempenho do controlador preditivo proposto.

According to the International Energy Agency (IEA-2013), Electricity alone does not create all the conditions for socioeconomic growth, but it is obviously essential to meet basic human needs and facilitate the development of economic activities. For the isolated areas with high wind potential and the island suffering from the electrification problems, the prospective solution is the use of renewable energies, especially wind energy. The present paper deals with a detailed statistical study on wind energy, its parameters, and variables on Socotra Island in Yemen, where that island is isolated from the main electricity grid in addition to the difficulty of providing electrical energy to this region in light of conditions in which Yemen has been living in recent times. The simulation results prove that the mean wind speed can reach a value ranging from 8.36 to 10.36 m/s, which is a large and enough speed to generate electricity using turbine farms. Based on the k and c Weibull parameters, the maximum probability at speeds 3 and 4 m/s is 0,052, while a value of 0,085 at speed 7 m/s is given by Rayleight distribution. Every result proved that Yemen has a good wind energy potential can utilize it for electrical energy production, and that strengthens the planning of economical wind turbines capacity for electricity production in the region.

This paper takes into account wind-DG hybrid configuration with a voltage source converter (VSC) as a voltage and frequency controller (VFC). Wind AC power generated by permanent magnet brushless DC generator (PMBLDC) is rectified into DC power, and maximum power is captured using maximum power point technique (MPPT) using a boost converter with incremental conductance (INC) approach. This power is stored into battery system (BS) and surplus is supplied to the consumer loads. BS is attached at DC link of VSC which provides load leveling during less or no wind conditions. Diesel engine driven squirrel cage induction generator (SCIG) is feeding loads and VSC at point of common coupling (PCC) to support the system when wind generation is unable to meet out load demand. Back propagation feed forward (BPFF) control scheme is used for VF control of VSC. This controller provides harmonics elimination, load leveling and reactive power compensation and also regulates the voltage at PCC. Microgrid is modeled with MATLAB Sim power tools and simulation resultsare produced to verify the appropriate working of both the converters and the overall system.
