Controlling of Micro-Grid by Sources Generating from Renewable Energy

Abstract

Electric distribution networks are getting old, and the cost of building new substations and networks is going up a lot. It's getting harder to get electricity to remote places because the cost of fuel is going up, making it sometimes impossible to do. On the other hand, places that aren't in the middle of nowhere are having other issues, like not having enough electricity because demand is rising and the quality of power and service is getting worse. In the last few decades, both the production and use of energy have grown dramatically. These days, the rise in spending has caused a shortage of supplies. So, we need to find a way to fix both the lack and the buildup of greenhouse gases. Renewable energy sources can be thought of as an alternative to the usual power sources that use fossil fuels. Micro-grids are a new concept in the energy industry that has a bright future and many benefits. Microgrids are like the main grid, but smaller. They are made up of a number of loads and scattered generation sources, most of which are likely renewable sources. These loads can get electricity and heat from nearby sources easily. This thesis suggests a way for micro-grids to control their energy. Using the ant colony method in Matlab to create an optimization algorithm for the combined economic and emission dispatch problem is how the suggested energy management system is put into action. Additionally, this study suggests a different, less expensive way to fix micro-grid problems: putting in a battery system instead of load shedding for times when the source can't meet the demand for power. There is a comparison between the cost of KWh of the battery and the cost of energy at the time of the cutoff to find the most efficient system.
