Hybrid Power Plants: Viability for Cities in Minas Gerais

Abstract

Abstract. The search for sustainability permeates present-day society, seeking new ways of development that combine the economic, social, and environmental sectors. The energy segment has an important role with regard to the change of developmental models. Hybrid models have been an effective way of electricity production around the world. Brazil has availability of both sources of energy (solar and wind power). Thus, the present work aims at investigating the potential of hybrid solar-wind energy farm in the state of Minas Gerais, especially in the Jequitinhonha Valley, the state's most needed region. The analysis conducted in the project showed that the cities studied present feasibility of deployment of renewable energy generation systems, whether hybrid or by a single source. In addition, the study shows that this would be a viable alternative and those investments, currently intended for the development of nuclear power plants could be destined for this type of generation since nuclear power plant put public health at risk.

Hybrid Power Plants: A Case Study

“…The region has a high poverty rate with high exodus to large centers and more than twothirds of the population occupying the rural area. The main human activities are related to agriculture, mining and garimpo [37].…”

“…Eq. (2) [37] represents the electricity generated by a photovoltaic system. It evaluates the area of the panel in m 2 (A); the efficiency of the panel in percentage (r); average solar radiation (H) and; a performance ratio, which represents the loss coefficient and ranges 0.5 and 0.9 (PR), the standard value of PR is 0.75.…”

Fractional Order Sliding Mode Control of PMSG-Wind Turbine Exploiting Clean Energy Resource

“…Hence, renewable energy resources have been measured as a best substitute energy source, because non-renewable energy resources like, fossil fuels are inadequate and create huge environmental pollution problems. Integration of renewable energy resources, such as; wind/solar energy with power system can be affectively improve the scarcity of clean energy, eliminate producing of harm gases due to diesel generators/coal, and will also lead to generate electricity with comparably low prices (Nguyen et al, 2013;Khan et al, 2018;Nascimento et al, 2017). With the expansion of higher capacity of wind energy, improved power compactness, advanced system consistency requirements and unfortunate low voltage drive through competence of the fractional order converters, several different forms of generation arrangements have been established newly.…”
