Abstract
Prosumers represent an important building block under the paradigm of a decentralized energy landscape such as outlined in the EU Clean Energy Package. However, the synergetic use of distributed resources such as electric vehicles (EV) or residential roof-integrated photovoltaics (PV) on household or neighbourhood level requires their diffusion patterns being temporally and spatially synchronized. This paper is dedicated to the joint analysis of their adoption patterns, using spatial analysis interfaced with mutual information and criteria ranking analysis. Surprisingly, outcomes for Portugal suggest that residential photovoltaics and electric vehicles are adopted by different population layers, as their occurrence is linked to diverging sets of sociodemographic criteria. Furthermore, an analysis of these criteria sets shows that their internal composition (the driving factors behind EV and PV adoption) varies among regions which has important implications on electricity network planning.

Abstract
Aggregated management of distributed energy resources (DERs) is an emerging topic mainly with simulation based investigation of the developed approaches. On the other hand, field tests can provide important insights on the path to wide deployment. Most of the works take into account aggregated DERs as a single entity and do not get into details about how to allocate a desired management target among them. This study focuses on management of different types of DERs as a group to reach aggregation targets through two field-testing scenarios. Active power management scenario investigates management of a DER group for an hour long period by allocating an overall target proportional to DERs energy storage capacities. Varying PV panel, wind turbine and residential consumer power profiles were also included in the testing scenario as a challenge to determine set points for manageable devices. Reactive power management case equally distributes aggregation targets among available DERs, comparing relative management performances in 4 consecutive periods. Management performances of individual DERs and the whole group were evaluated, highlighting management accuracy and possible challenges in the field.
