Across the US, more states and electric utilities are setting 100% clean energy goals of which renewable technologies will be a major player. Variable renewable energy like wind and solar photovoltaics (PV) differ from conventional generation in that they use power electronic converters instead of synchronous generators to connect to electric power grids. At small levels, the power grid can easily handle the integra􀆟on of variable renewable energy. At much higher levels, there are a number of technical concerns that must be addressed to ensure reliable and economic operations. This presentation will discuss the challenges and solutions to operating power system with high levels of variable renewables and how power electronic inverters and specifically grid-forming inverters can be used to solve some of these challenges.
