Flexibility offered to the distribution grid from households with a photovoltaic panel on their roof: Results and experiences from several pilots in a Norwegian research project

The objective of this study is to evaluate how PV-oriented prosumers can offer flexibility to the Distribution System Operator (DSO). The different cases focus on the customer and changes on the customer side that will benefit both the customer and the distribution grid. (Actual tests of services delivered to the DSO have not been performed.) The study also highlights the importance of being proactive about the placement of roof top panels near the loads in the grid for a better balance between PV-output and loads at the terminal points in the grid. This approach demonstrated the secure operations of the grid well below the capacity limits and yield better rewards for the prosumer. In this study, storage options at the prosumer side are also considered and both technical and economic aspects are analysed. Special emphasis is placed on the impact of power tariff structures that include capacity considerations.
