SYSTEMS AND METHODS FOR REDUCING HARMONIC CONTENT IN A POWER NETWORK HAVING DISTRIBUTED ENERGY RESOURCES AND DISTRIBUTED INVERTER SYSTEMS

A controller system reduces destructive harmonic content within a power network system, the power network system comprising one or more distributed energy resources, one or more distributed inverter systems, one or more nonlinear loads, and a bus coupling the one or more distributed energy resources to the one or more nonlinear loads. The controller system comprises one or more sensors; one or more hardware processors; and memory storing computer instructions, the computer instructions when executed by the one or more hardware processors configured to perform receiving, by the one or more sensors, sensor data indicative of destructive harmonic content of a particular order on the bus; and using a particular distributed energy resource and a particular distributed inverter system to inject constructive harmonic content to reduce the destructive harmonic content.
