An unexpected challenge facing network operators due to high penetration levels of small-scale solar photovoltaic occurs when diesel backup generators are used to maintain supply to small network islands during maintenance. Most grid-connected small-scale solar inverters in Australia have no means of grid control and it is uneconomical to individually isolate each device within premises. Taking advantage of out of frequency protection settings of the inverters to disable output of distributed generation is one potential mechanism Network Service Providers are considering when operating the die...

Voltage rise caused by high levels of distributed generation is manifesting as voltage regulation challenges for many electricity network operators. In this environment it would be ideal to reduce supply voltage magnitudes, however, many network operators are hesitant to do so due to concerns related to appliance operation at reduced voltage magnitudes. Voltage regulation requirements are defined by network standards and network service providers must ensure voltages remain within specified limits. Through an extensive evaluation of domestic appliance performance when supplied at various volta...
