Coordinated Storage and Flexible Loads as a Network Service Provider: a Resilience-Oriented Paradigm

A resilience-oriented operation multi-time scale scheduling is proposed in this paper that deploys a coordinated storage and flexible loads (CSFLs) structure to act as a network service provider (NSP). The proposed proactive operation strategy can deal not only with intermittent wind generations in hourly operation but also with load supplying resilience for the sub-hourly variations. The energy storage systems (ESSs) can retain the state of charge (SoC) during the sub-hourly fine-tuning periods to supply critical loads for predefined time intervals. In this regard, by integrating the so-called NSPs into a stochastic unit commitment model, the advent-ages of ESSs and flexible loads (FLs) are taken to enrich the short-term scheduling for the different time resolutions. The proposed model is tested by the IEEE RTS-24 standard network. The results show that NSPs can successfully participate in providing coordinated ancillary services in different time-scales, and concurrently by support of FLs, the ESSs proactive role is also retained. The usage of CSFLs reduces the curtailment of wind energy, while they provide a large portion of reserves for the possible fluctuations.
