Robust integrated-energy management of shared transmission systems for renewable fuels and refined oil considering decision-dependent pressure drop uncertainty

This paper investigates robust integrated-energy management (RIM) of shared transmission systems for renewable fuels and refined oil (STS-RR) considering decision-dependent uncertainty (DDU) in pipeline pressure drop to ensure security and efficiency of system operation. Firstly, the two-stage RIM model in STS-RRs is proposed. Specifically, in the day-ahead pipeline schedule stage, the integrated-energy management of electric pump operation, multi-batch flow delivery and chemical drag reducer (CDR) injection within STS-RRs is considered to reduce energy consumption and operational costs. In the intraday adjustable operation simulation stage, the uncertainty in pressure drop due to decisional CDR injection concentration and pipeline flow rates is characterized by DDU. Additionally, the adjustable in-station facilities are regulated corresponding to pressure drops within the uncertainty sets. Correspondingly, the solution workflow is proposed to simultaneously handle both decision-independent uncertainty and DDU. Finally, extensive case studies on an illustrative STS-RR and a real-world cross-regional multi-product transmission system in South China validate the effectiveness and scalability of the proposed RIM framework, where a 32.24% energy consumption reduction, a 22.20% economic improvement in total cost and a 26.08% increase in turnover for the illustrative case are achieved. Importantly, the DDU-aware modeling reduces unnecessary conservativeness.
