The article helps in addressing multi-objective function and stochastic for microgrid energy management problems. The key element of the article is the results of the simulation analysis conducted by the scholars; it determined that Epsilon constraint mathematical model can play a significant role in the energy management microgrid. It can be evaluated that there are numerous uncertainties associated with energy management parameters such as thermal and electrical load and renewable energy sources. Hence, multi-objective problems can be reduced by Epsilon constraint mathematical model.
The effect of non-sustainable and sustainable energy sources on the economic growth of a country was critically discussed in the study. The key element of this study is the empirical analysis conducted by the scholars; the results stated that countries like Ukraine, Korea, Netherlands, Mexico, Peru, Chile, Greece, Japan, Ireland, Kenya, Austria, Australia, Bulgaria, Sweden, Norway, Poland, Slovenia have a major renewable resource which is contributing in the growth of the economy of these countries. It can be evaluated that factors such as government utilities on energy policies, green certificate training, tax exemptions in solar cells, and investment subsidies are hugely affected in these countries due to the presence of the abundant amount of renewable energies.
The articles suggested a hybrid PV battery driven dc bus system that can help eliminate the ac-dc conversion stage; it can help in lowering the cost and improve energy consumption efficiency. The key findings of the study are the comparison among AC and DC inputs for selected AC adaptors. It can be evaluated that the proposed PV battery dc-dc converter provides a higher voltage conversion ratio and lower voltage stress as compared to the traditional boost converter.
