“…Normally affect such as either the nearby feeder can accommodate electrical burden of the faulted area or there is overvoltage occur due to the backfeeding. Analysis of overvoltage is highly important because it might damage the power system infrastructure and customer electrical equipment [1,15].…”

In power system, power outages can be critical; if the environment and public safety within risk situation. Therefore, restoration power is needed to respond on system distribution to reduce the power restoration time and making the system reliable and efficient. Backfeeding using a nearby feeder in a power system is proposed in this research. When a power outage occurred, the faulted area is isolated from the system and searching available nearby feeders that can restore the outage area without any violation. However, analysing the effects of using a nearby feeder for back feeding is needed to avoid voltage violations. This paper analyses the voltage during the healthy and faulted condition, the impact of using a nearby feeder for backfeeding for a full load, half load and during no-load conditions are examine and also determine the maximum increment limitation of a load during back-feed if a qualified feeder is selected. Newton Raphson method is applied to calculate the power flow in the system and observe the stability of backfeed configuration. The results show the highest voltage supply occur during no load followed by half load and lastly during full load. The maximum voltage increment of load on backfeed is determined to be 0.95pu as an ideal voltage value.

“…Therefore, it is beneficial to managing and controlling DERs. However the conventional protection and control method in spot network cannot adopt DERs friendly, which has not been studied and documented in depth [13][14][15][16][17][18]. The traditional protection in spot network is listed in Table 1 [12].…”

“…Nevertheless, with the development of renewable energy, more and more DERs will be connected into the spot network and most DERs work with intermittent and random output. The excess power inside the network will make the reverse protection false trip frequently [15][16][17][18][19][20][21]. To enhance the adopting ability for DERs, the inverse time strategy is introduced to improve the reverse power protection scheme.…”

“…In repetitive, severe cases TOV can lead to loss of life of plant [4][5][6][7][8][9][10][11][12][13][14]. The dedicated research from Ketabi [5] has shown a new approach that assists power system restoration planning with regards to control of temporary over-voltages mainly caused by transformer energisation.…”

TasNetworks own and operate the Network Control System Protection Scheme and provide this service to Basslink Pty. Ltd. NCSPS was designed and implemented to maximise the power transfer capacity on transmission corridor. Due to the evolution of the Tasmanian power system, there is a need to review the network security risks of Temporary Over Voltage (TOV) following certain NCSPS action at Hadspen-George Town 220 kV transmission corridor. Appropriate limit advice and constraint equations are developed and invoked for the secure operation of the power system. This paper describes the system studies and observations used in constructing the TOV limit advice.
