Massive deployment of distributed energy resources, predominately renewable, is expected to be a general trend in the near future. Integration of such elements in distribution grid represents one of key challenges that Smart Grids will have to face with. In this work we aim at bridgingindustrial and academic views on future trends in this field. We list main issues to be tackled and we propose a conceptual system-level solution based on Multi-Agent Systems. We show basic functionalities and structure for supporting ICT architecture.
