Effects of load control for real-time energy balancing on distribution network constraints

摘要

This paper studies the effects that load control for balancing services has on the physical constraints of a distribution network. A simulation study is conducted across a range of scenarios and prototypical distribution networks. Network constraint violations, such as over-voltages and blown fuses, are recorded and compared to a no-control baseline simulation. Notably, the simulation results show that no instantaneous constraints are violated due to load control. We find that the mean aging rate of the transformers decreases in 24 of 25 simulations, though in 21 simulations a majority of transformers experience increased aging rates. Overall the results indicate that load control for balancing services is unlikely to cause emergency-level issues on a distribution network. However, longer term impacts, such as increased aging of certain transformers, may warrant a control design that manages particular network constraints.
