ABSTRACT

The harmful outcome of fossil fuel emission and growing concern about the deficiency of power resources has started a new requirement of cleaner, reliable, and sustainable energy resources. Thus, wind power and solar energy based systems are the best emerging energy sources amongst the various renewable energy resources. The proposed system involves a boost converter with an inverter circuit, where first solar and wind energy is regulated, and the inverter is employed for grid integration. In the proposed work, model predictive control is applied to a 3-phase inverter and it uses a model to estimate the predictions of upcoming values of the system voltage for a provided sequence of voltages. Further, the cosine firing angle arrangement is also used for adjusting the output voltage of the boost converter. The three-phase inverter is also employed as a harmonic reduction device, this allows the utility grid to continuously supply or absorb the good quality of power. The proposed approach escapes the use of nonlinear and linear controllers and it does not include the modulator, hence this is a simple method and the control algorithm is easy to implement. The outcomes show that the planned scheme has excellent performance.

摘要

化石燃料排放的有害结果和对电力资源短缺的日益关注，引发了对清洁、可靠和可持续能源的新需求。因此，基于风能和太阳能的系统是各种可再生能源中最好的新兴能源。所提议的系统涉及带有逆变器电路的升压转换器，其中首先调节太阳能和风能，并且逆变器用于电网集成。在拟议的工作中，模型预测控制应用于三相逆变器，它使用模型来估计对提供的电压序列的系统电压即将到来的值的预测。此外，余弦点火角布置还用于调节升压转换器的输出电压。三相逆变器也被用作谐波降低装置，这使得公用电网能够持续供应或吸收优质电力。所提出的方法避免了非线性和线性控制器的使用，并且不包括调制器，因此这是一种简单的方法并且控制算法易于实现。结果表明，所规划的方案具有优良的性能。
