Microgrid concepts and models for the electrical grid of an industrial district

The paper is aimed at describing an on-going project for the definition, modelling and implementation of a microgrid within an industrial district. The project intends to facilitate the integration of renewable generation sources in existing energetic districts including industrial and tertiary service companies. The behaviour of generation, load and storage systems will be modelled and studied in order to understand, propose and test strategies for the integrated participation to the electricity market both in terms of energy supplied and of ancillary services provision. The microgrid is modelled by means of a software tool that allows to simulate the behaviour of the electrical system and the combined action of generators and loads and to propose and test possible management strategies. The architecture proposed for a DMS – Distributed Management System, that allows to control the industrial district, is also presented. Adopted optimization tools and methodologies are described. Some scenarios useful for individuating future test to be performed on field are presented and simulation results are provided and commented.
