The calculation of white certificates aims to highlight how the energy consumed in different time states (from unconventional sources), has a variable content. The goal is not to influence the production mix, for us, the production mix gives us a measure of how much really, in each hour you are consuming that amount of energy. We will focus on ‘how much’ and ‘when’ changes in power consumption due to an Energy Efficiency Measure impact on the Italian energy system and its possible value. In particular using the hourly energy mix f the national system and the hourly profile before and after the intervention, we propose to introduce a time based evaluation of white certificates In the whole analysis, we consider two distinct interventions implementing efficiency by renewable energy self-consumption: photovoltaic installation and phtovolt...

The aggregation of nanogrids in a community, connected via public distribution network, allows to generate added value both to the members of the community and to the electrical system. Following this paradigm in fact, flexibility may be exploited in two forms: flexibility within the aggregation (or energy flexibility) in which each member of the aggregation responds to obtain a reduction in its energy supply costs and an external flexibility, in which it offers ancillary services to network operators receiving an appropriate payback. In the paper, the proposed management model of nanogrid community able to exploit internal and external flexibility of the aggregation is presented. The management model developed in the ComESto project is presented to take into account simultaneous...

It will require a necessary energy transition characterized by a continuous increase of generation facilities from renewable energy sources (RES), from a massive increase in energy efficiency and, contemporary, an increased use of electricity to meet the energy needs traditionally required through the direct use of fossil fuels. In order to provide end-users with a greater knowledge and awareness of their energy consumption and the benefits of distributed use of renewable energy sources, it is fundamental to employ a smart metering progress which can enable an evolved and ‘smart’ management of the production–demand binomial and an active participation in the energy system. The importance of functionalities implemented in a smart meter—for end-user engagement, empowerment, and awareness—is presented in the paper. For instance, we present a simple optimization functionality for ...

The renewable energy community of users equipped with nanogrid technology allows performing an adequate level of flexibility. It may be the solution to coordinate in the best possible way the energy resources in order to increase the community self-consumption and to provide ancillary services to the grid. In this paper, a model for the interaction between the Distribution System Operator (DSO)—Transmission System Operator (TSO) and the energy community based on nanogrids is proposed and an operational example is presented.
