Advanced Smart Solar Inverters
Speaker: Frances Bell
Senior Power Systems Engineer at SolarCity
About the talk
Distributed Energy Resources (DERs) such as PV, fuel cells, energy storage, wind turbines, require an inverter to interface with the grid, which are designed to act as ideal current sources. “Smart” inverters refer to standard power electronic inverters with advanced features enabled. The most market-ready list of those advanced functionalities currently comes out of California’s revamped Rule 21 Interconnection, which identifies the following autonomous functions of smart inverters:
‒ Anti-islanding protection
‒ Low and high voltage ride through
‒ Low and high frequency ride through
‒ Dynamic Volt/VAR support
‒ Configurable ramp rates
‒ Flexible power factor
‒ Soft start reconnection
Standards are currently being developed that outline how smart inverters can be coordinated by central controls on distribution, which could dynamically adjust ramp rates, power factors and volt/VAR responses. This talk will dive into the smart control capabilities of today’s smart inverters, then discuss the new research and pilot projects SolarCity is implementing to drive smart inverter capabilities further.
