Distributed generation systems
Distributed Generation is a model of the production and distribution of energy that is based on the integration in electricity networks of small/medium-sized renewable source and co-generation plants (often natural gas) generally connected to the distribution network. The plants are often located near the end user, thus contributing to reducing the need for investments and infrastructure to increase the carrying capacity of the transmission and distribution networks and at the same time reducing network losses and distribution costs.
Distributed Generation can supply more reliable and better electrical quality power. The ability to quickly give back power to a user network and in the future to distribution areas can give greater security to the system, thus reducing the risks and effects of any blackouts.
The increasing demand in energy, along with the need for guaranteed electricity supply and the reduction of greenhouse gases, find the essential components for sustainable development in the growth of distributed generation and renewable source technologies.
The liberalization of the electricity market, the adoption of environmental international objectives such as the renewable directives, and the continuous development of generation, automation and communication technologies are the elements that support the interest in and the increasingly greater development of the distributed generation concept.
The objective of RSE activities in terms of distributed generation is the assessment of Distributed Generation technologies and the study of active distribution networks. In addition to the accomplishment of the Test Facility Laboratory, RSE activities in this area are focused on:
. Study of new measures to increase the quantity of DG in distribution networks, such as for example the possibility to moderate the power input from the generators or the output from the loads (the so-called "active resources").
. Development and experimentation of software tools to assess the impact of DG on network costs and operation reliability; evaluation of new network operation procedures in the presence of "active resources";
. Assessment of the effects of DG on the quality of the service network
