Nocturnal electric vehicle charging interacting with a residential photovoltaic-battery system: a 3E (energy, economic and environmental) analysis
摘要： Increasing costs of petroleum derivatives, limitations on pollutant emissions and development of photovoltaic (PV) and electrical storage systems make it possible to spread the use of electrically powered vehicles. In this work, a 3E (energy, economic and environmental) feasibility study was carried out regarding an nocturnal electric vehicle (EV) charging in a residential user. In particular, three different EV charging scenarios were considered: use of the grid; use of a grid-connected PV system with a storage battery; use of a grid-connected PV system with a storage battery in the presence also of a residential user. Two sub-scenarios were examined that foresee the purchase of the EV as an alternative to a vehicle powered, respectively, by petrol and diesel. By considering different daily average distances travelled, a parametric study was developed in order to assess the influence of the size of the PV and storage system on the load satisfaction and solar energy utilization, economic convenience and emission savings. In general, it is not possible to simultaneously comply with all the 3E objectives and constraints. However, it is possible to select optimal EV-PV-battery combinations from a unique point of view or those that lead to a trade-off.

[IEEE 2018 IEEE International Conference on Smart Energy Grid Engineering (SEGE) - Oshawa, ON (2018.8.12-2018.8.15)] 2018 IEEE International Conference on Smart Energy Grid Engineering (SEGE) - Effects of Centralized Battery Storage Placement in Low-Voltage Residential Distribution Networks with High Photovoltaic Penetration
摘要： In this paper, power flow simulation is used to investigate how centralized battery storage can aide in mitigating under-voltage conditions in highly PV penetrated residential network. It also investigates how the placement of the battery storage relates to the rating of the storage used. It is found the reduction in storage rating is quadratically proportional to the distance along the low-voltage distribution feeder.
