Abstract

Under the background of the energy revolution, the new power system is gradually transforming into the energy Internet. With the large-scale penetration of wind power and the diversification of service modes of regional integrated energy systems, the uncertainty of source and load has become a difficult problem in the planning and operation of large-scale integrated energy systems. Aiming at the above problems, this paper proposes a highly general distribution-integrated integrated energy system distribution robust scheduling method. First, the large-scale new IES is divided into electric-gas transmission network and multi-energy flow energy hub distribution network. The power-gas-heat-hydrogen system's distribution and transmission process is finely modeled; then, an uncertain set of wind power and multi-energy flow loads based on discrete scene sets of historical data is constructed, and a data-driven comprehensive energy system with integrated transmission and distribution min -max-min two-stage distribution robust optimization model; Finally, the non convex airflow equation is transformed into a second-order cone form, and the original MINLP problem is transformed into a MISOCP problem. After dual transformation, the overall model is solved using the SOC-C&CG method.
