Renewable sources of energy are becoming more and more applicable in home systems and power plants. Smaller systems are able to function separately, however connecting them into a network has several advantages. During cloudy or windless days, those kinds of systems don’t generate enough electrical energy. This issue can be surpassed if there is a grid that can compensate for the lack of power generated from a single input point. Moreover, when the weather is suitable for producing excess energy, this surplus can be given to the grid to help supply the underperforming sectors. The connection is achieved by employing elements of power electronics which generate higher harmonics destructive for the grid. An LCL filter is used to reduce these effects.
