As you all know, the TSO and DSO need Ancillary Services (AS) to maintain the security and reliability of the power system. What kind of Ancillary Services the Electric Vehicles can provide to the TSO and DSO?
In DSO, Electric Vehicles can reduce power losses and overvoltages caused by the high penetration of distributed generation, for example, photovoltaics.
In an LV distribution network, when analyzing technical losses behaviour versus penetration level of photovoltaic generation in a daily operation, for example. As penetration level increases during times of greater solar radiation, technical losses reduce to a certain penetration level. After that, with photovoltaic generation massive connection, technical losses increase too much. In this way, electric vehicles can contribute to reducing losses by balancing distributed generation and demand.
