On the Impacts of Multi-Agent Transactive Energy in Distribution Networks - Part 2: Integrated ETSim Results and Findings

The integrated quasi-static Generic Time-Series Power Flow (GTSPF) and transactive energy ETSim platform aims to simulate transactional exchanges associated with electricity generation from distributed energy resources (DERs) and analyze the resulting impact and advantages on the distribution network. In this work, the integrated ETSim platform is tested by using the IEEE 13 node test feeder, six different scenarios are evaluated which vary in terms of DERs penetration, tariff type, and DERs optimization objectives. The analysis of these scenarios has demonstrated that when tariff structures and market frameworks promote the efficient utilization of DERs and encourage energy exchange between the grid and DERs owners, there can be both positive and negative impacts. However, effective management of network stress, ensuring a stable and reliable electricity supply, it becomes possible to avoid network upgrades and brings economic benefits to both grid operators and users. The analysis offers an evaluation of multi-agent transactive energy systems in distribution networks considering the spatial and temporal correlations of multiple DERs for a proper operation of power system with high penetration of renewable energies.
