Dynamic Active Distribution Network Reconfiguration Considering Aging Mitigation of Enrichable Battery Energy Storage Systems

To avoid worldwide climate change effects, decarbonization initiatives transit the distribution systems to be mixed with a high penetration of distributed energy resources (DERs) and enrichable battery energy storage systems (BESS) units. Since the degradation of BESS units is highly relevant to their discharging/charging operations, this paper considers constructing the dynamic DNR model with the aging mitigation of BESS units. This can extend the reaming useful life of BESS units, whilst achieving the minimization loss and smoothing power fluctuations of DERs. For the BESS aging cost, we derive the linearized hyperplanes to approximately quantify the battery life loss, which facilities for the solvability of the dynamic DNR model as a mixed integer second-order conic programming (MISOCP) problem. Case studies demonstrate that this proposed dynamic DNR model can achieve these merits with satisfactory performance.
