| Objectives | HV and LV monitoring will be installed before and after IPT charger commissioning in order to retrieve background harmonic levels. 1. Install HV and LV monitoring devices on the adjacent network2. Conduct preliminary lab testing of the IPT charger3. Connect IPT chargers to the network using innovative techniques4. Demonstrate charge deferral based upon network constraints5. Develop an IPT charger connection policy | |
| Abstract | A capacity of 120kVA is required to deliver sufficient charge to the bus within the short window of time it will be waiting at a bus-stop. A linear load of this size should be able to be supplied by the low voltage system in most cases without thermal ratings being exceeded, however the non-linear equipment used in the IPT system is likely to cause high levels of harmonic voltage distortion. WPD Policy Document ST6J does not allow this equipment to be connected at LV and so connections would need to be made at HV, increasing the cost and acting as barrier to uptake. WPD will also be developing and demonstrating the ability of the existing network off-peak capacity to be used to charge electric vehicles. WPD will investigate and compare innovative techniques of connecting the IPT chargers to the grid without conventional HV reinforcement. Harmonic disturbance on the adjacent network will be monitored and controlled where possible. Opportunities for deferment of electric bus charging at times of network stress will be investigated and how active management can enable the uptake of this infrastructure. Traditional load on the LV network tends to drop off during the evening and overnight, which would free up capacity to deliver charge to electric vehicles without triggering upstream reinforcement. The delivery of this charge will need to be managed in order for the network to remain within thermal and voltage limits. Using technology, the level of charge can be managed and prioritised according to anticipated charging window of the vehicle, which will allow more vehicles to be charged simultaneously at the same location.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above | |
