Real-life demonstration of blockchain based flexibility trading between FSPs and DSO

This study demonstrates the flexibility trading process between a distribution system operator (DSO) and potential flexibility service providers (FSPs) using a framework consisting of a blockchain-based P2P trading platform and other auxiliary platforms. Within this framework, a demo study was conducted with real distribution system's assets and systems on the trading platform where the DSO specified its flexibility needs and FSPs were able to offer their flexibilities to support the DSO. In the study, vehicle-to-grid (V2G) compatible electric vehicle charging station and stationary battery storage system were used as flexible assets. The trading process was conducted within the specified time and price range through the platform, involving the FSPs and the DSO. As a result, the flexibility was provided to a local LV grid, leading to a 17% reduction in the load of the distribution transformer owned by the DSO.
