Energy Communities for the Energy Transition
Renewable sources, such as photovoltaic panels and wind generators, and storage devices, like batteries and electric vehicles, are usually connected to the grid for cogeneration. This connection is made through power electronics interfaces that should ensure high stability, voltage regulation, power flow control, and low electromagnetic emission, along with high power density, low cost, and high reliability. To increase the power density, passive devices that are considered the bulkiest components in these systems should be reduced or avoided. This can be achieved by considering multilevel topologies that would comply to power quality requirements without the need of passive filters. In addition, matrix converters are promising structures to connect wind generators to the grid without the use of a bulky DC storage device.
