Performance Evaluation of Grid with Hybrid AC/DC Methodology

Renewable energy systems such as PV, solar thermal electricity such as dish-sterling systems, and WT are appropriate solar and wind technologies that can be considered for electric power generation at the distribution system level. Other renewable energy technologies, such as the solar central receiver, hydro-electric generation, geothermal, and large wind farms are normally connected to the grid at the sub-transmission or transmission level because of the higher power capacities of these types of systems.Due to increasing air pollution, global warming concerns, diminishing fossil fuels and their increasing cost have made it necessary to look towards Renewable Energy Sources (RES) as a future energy solution. Interfacing these RES applications to grid connected system as well as standalone system utilizing the power electronic converters.
