Abstract:The adoption of variably generated renewable energy sources and the shift to electric transport and heating is imposing new demands on the power grid. Congestion occurs when the local demand for energy transportation exceeds the physical limitations of the grid. The flexibility of many electrical devices allows mechanisms to be deployed that mitigate congestion. To prevent power outages, a mechanism is needed that intervenes by controlling flexible devices when congestion occurs. For such mechanisms, uni- directional control algorithms provide regulatory and privacy advantages over bi-directional approaches, which require data to be published by the connected devices. However, uni-directional control algorithms do not yet consider the requirements of individual users as bi-directional approaches do. This paper presents and examines the effectiveness of a novel uni-directional congestion mitigating measure that considers individual user requirements using uni-directional auctions, such that priority is given to users with a higher need for grid capacity. Various algorithms are evaluated in a simulated low-voltage grid of ten households, uni-directional auctions are 94.3% as effective as their bi-directional counterpart at mitigating congestion, and 87.6% as effective at meeting user requirements.
