Power generation in microgrids is based on small-sized generating units, typically ranging from less than a kW to tens of MW, connected at the distribution network on-site or near the load demand. Renewable energy technologies for microgrids exploit sustainable energies such as wind energy, solar power, smallscale hydropower, bioenergy, and geothermal power. Many countries in the world have been implementing policies to promote the deployment of renewable generating technologies aiming at reducing the greenhouse gas emissions, principally the exploitation of variable output renewable energies mainly based on wind and solar photovoltaic (PV). The continuous and robust deployment of these types of renewables and their relatively easiness for sizing and installing have set the expectation that power generation integrated into microgrids will be based predominantly on these technologies. Hence, this work focuses on wind and solar photovoltaic generation technologies for microgrid applications. In this document, detailed models to simulate its dynamic performance are presented, including the power conditioning system and the control strategy for grid-tied operation.
