Digital Energy Platforms Considering Digital Privacy and Security by Design Principles

The power system and markets have become increasingly complex, along with efforts to digitalize the energy sector. Accessing flexibility services, in particular, through digital energy platforms, has enabled communication between multiple entities within the energy system and streamlined flexibility market operations. However, digitalizing these vast and complex systems introduces new cybersecurity and privacy concerns, which must be properly addressed during the design of the digital energy platform ecosystems. More specifically, both privacy and cybersecurity measures should be embedded into all phases of the platform design and operation, based on the privacy and security by design principles. In this study, these principles are used to propose a holistic but generic architecture for digital energy platforms that are able to facilitate multiple use cases for flexibility services in the energy sector. A hybrid framework using both DLT and non-DLT solutions ensures trust throughout the layers of the platform architecture. Furthermore, an evaluation of numerous energy flexibility service use cases operating at various stages of the energy value chain is shown and graded in terms of digital energy platform technical maturity, privacy, and cybersecurity issues

Impact of local electricity markets and peer-to-peer trading on low-voltage grid operations

Local electricity markets based on peer-to-peer (P2P) trading schemes have emerged as an innovative mechanism to sell electricity from prosumer to consumer, to utilise efficiently and value local flexibility, and to support grid management. In this paper, we analyse a local market applied to a real-life neighbourhood of 52 households in Norway. As prosumers and consumers trade within this community, we analyse the value of P2P trading compared to cases where no local markets are available, along with the impact of PV, batteries and EVs deployment. As these technologies and local trading interactions might create challenges to the physical operations of the grid, we analyse the effect on power flows, voltage variations and system losses. The main findings indicate that there are no significant impacts on the grid operation of the P2P market when only PVs are installed in the system. With decentralised batteries available, the P2P trade induced more voltage fluctuations and 14 % more losses within the neighbourhood than the case with no local market. However, the local market brings overall savings for the end-user and sets the frame to design pricing schemes (e.g. manage losses) that are tailored to support DSO operations
