Distributed flexibility as a cost-effective alternative to grid reinforcement [article]

Jordan Holweger, Christophe Ballif, Nicolas Wyrsch
2021 arXiv   pre-print
Our results highlight that using distributed flexibility is more profitable than reinforcing a low-voltage network until the PV generation covers 145% of the network annual energy demand.  ...  In this work, we assume the DSO can control each prosumer's battery and PV system. Under such assumptions, we evaluate the cost of providing flexibility and compare it with grid reinforcement costs.  ...  Future work may repeat such a study for a wider range of networks with different topologies and load characteristics and extract insights to better understand the profitability of distributed flexibility  ...
