A case study in the future challenges in electricity grid infrastructure

The generation by renewables and the loading by electrical vehicle charging imposes severe challenges in the redesign of today's power supply systems. Indeed, accomodating these emerg- ing power sources and sinks requires traditional power systems to evolve from rigid centralized unidirectional architectures to intelligent decentralized entities allowing a bi-directional power flow. In the case study proposed by ENDINET, we investigate how the penetration of solar panels and of battery charging stations on large scale affects the voltage quality and loss level in a distribution network servicing a residential area in Eindhoven, The Netherlands. In our case study we take the average household load during summer and winter into account and consider both a radial and meshed topology of the network. For both topologies our study results in a quantification of the levels of penetration as well as a strategy for electrical vehicle loading strategy that meet the voltage and loss requirements in the network.Electrical Engineering, Mathematics and Computer Scienc
