要約(英語): A large number of photovoltaic generation systems (PV) are being introduced into distribution systems. Massive PV integration requires some technical challenges such as voltage control, unbalance compensation, feeder capacity management, etc. The authors focus on the restoration process after the feeder line failure. In the restoration process, the power flow observed before the failure occurrence is often used to certainly avoid feeder overloading and voltage violation during the restoration process. However, most of the PVs are suspended by the islanding detection system, and therefore, the actual loading under the restoration process would differ from the observation before the failure. For a reliable restoration, feeder current estimation based on the actual load is important. This paper proposes a load-generation disaggregation method for an arbitrary area based on the measurement information from smart meters and IT switches. The numerical case studies for the distribution network model with 4,320 consumers were carried out to validate the estimation performance.
