The dynamics imposed on the electric mobility market and environmental and technological issues lead to a paradigm involving various energy chain agents, from producers, consumers, traders, and network operators.
From the outset, private users and entities are faced with various mobility solutions, including vehicles with a thermal engine, hybrid, or purely electric. In the case of EV (Electric Vehicles), decision-making includes choices that are covered with different levels of sophistication, from charging an electric vehicle from a simple single-phase 16 A socket to more complex solutions that fit the assembly of Wallbox.
Other variables, such as the type of charging (fast/slow) and battery life, are also important. The most appropriate tariff option for each case and the maintenance inherent to each type of mobility solution make the decision denser.
Concerning energy production (self-consumption) and considering the user profile, it will be essential to reflect on mobility solutions that think of renewable energy production (solar photovoltaic, other) in which the EV can be a storage point for that energy with the consequent assessment of the potential economic benefit and the resultant minimization of the ecological footprint, highlighting the carbon footprint.
On the other hand, all these dynamics of sustainable mobility will impact the electrical grids. The network operator will now have to deal with these “new” realities, minimizing the impact on the network, namely in terms of power flow and in terms of the quality of the voltage wave. Also, at the end customer level, there are reports of situations in which inverters “withdraw” photovoltaic production from the grid in the face of disturbances in the quality of the voltage wave. These situations must be assessed at the level of the network operator when they have external causes at their origin or at the level of the consumer when the source of the disturbance is internal.
The present project proposal intends to contribute at several levels in several agents: users, energy producers (self-consumption), network operators, general public due to possible ascertainable environmental benefits.
The intended results include the guidance of dissertations, digital platforms, and publication in scientific journals and communications. Protocols for the study of sustainable mobility solutions within the scope of local agents may also be framed. In terms of results, it will also be essential to organize dissemination activities to disseminate the results obtained within the community and improve the visibility of research and development work in the mobility and transport sector.
