about the need to provide alternative schemes in cases where the EV penetra-
tion is well below expectations. In this sense an iterative process was devel-
oped to determine the necessary volume of extra storage required by the
critical case, 50% of EV penetration, to ensure that system requirements
are met.
The results of this analysis are shown in Fig. 8.13. The associated addi-
tional storage capacity provides the necessary increases in the power genera-
tion limit of flexible resources to avoid transmission congestion. It is worth
mentioning that these limits are defined by a combination of factors as
described in Fig. 8.1.
8.7 Conclusion
The coordination of distributed generation, renewables, and flexible
resources enables a completely new level of applications to distribution
systems. In this perspective the smart management of these elements during
the planning stage, followed by a comprehensive assessment of predicted
values that may become well below expectation, as is the case for EV pene-
tration, can provide a holistic and improved distribution system planning.
