The Micro Grid Management System of Small and Medium-sized Farms

Abstract

The pollution treatment of farms mainly transforms excrement into biogas. However, in actual life, improper use of biogas results in second environmental pollution. In this paper, a micro grid system based on farms and biogas is used to produce power to meet the daily load demand, furthermore, the system also includes wind turbine, photovoltaic cells, fuel generator, and energy storage system. Genetic algorithms used to optimize the output of different renewable energy sources, as well as the system support isolation running and connection running. We combine historical data and meteorological data to predict the generation of wind turbine, photovoltaic cells, and the result as an output. Hence The effect of randomness on Micro-grid system optimization is effectively solved. Finally, an example is given to obtain the final optimization results in order to achieve the lowest cost.
