Grid-Connected Inverter Testing and Assessment
Inverter testing is fast becoming an important capability as the penetration of distributed generation , like photovoltaics and battery storage systems , rapidly increases . A comprehensive test setup that can accommodate inverter capacities between 1kVA and 50kVA has been developed , which allows inverters to be tested to the edge of their performance envelope . The testing system can also be utilised for coarse and fine tuning of inverter control parameters . |
Competitive Advantage • Best-in-class Inverter testing system , operated by staff with diverse experience in testing a variety of inverter types , makes and models
• Specialist knowledge allows the identification of inverter vulnerability to grid disturbances , which may cause unexpected behaviour in inverter makes and models – important for Virtual Power Plant solutions and microgrid providers
Impact • Testing allows for rapid determination of gridconnected inverter behaviour and control , and the fast assessment of vulnerabilities for a range of typical grid disturbances
Successful Applications • Over 15 inverter makes and models tested for an ARENA funded project into the effect of distributed energy resources on the distribution grid
|
• Fine-tuning of critical subsystems , such as synchronising algorithms ( PLL , FPLL , SOGI , VSG ), current mode control , voltage-source forming and fault characteristics
