The electrical systems of the future represent a challenge for engineering due to the decentralization of power flows and the dynamic behavior between generation and consumption agents. This fact implies the need to implement changes in the structure of current networks, trying to adapt and take advantage of the existing infrastructure in this new paradigm of operation. In this way, the planning of the networks must consider non- conventional renewable sources of intermittent nature, energy storage, flexible loads, etc. In particular, one of these controllable loads are the electric vehicles. This course presents the tools for, first, the transmission and distribution systems planning considering these new challenges, and second, the relationship of the electric vehicle charging tools with the aggregate demand profiles and power transformers management.
