Abstract

The invention discloses a methane-wind-light full renewable energy system based on an energy hub and a methodthereof. The method comprises the following steps: constructing a full renewable energy system based on a methane-wind energy-solar hub; carrying out detailed modeling on an energy hub containing an energy storage element, processing the energy hub into a linearized matrix which is more adaptive to system optimization scheduling, and then further considering the output uncertainty of wind-solar renewable energy sources; and constructing a day-ahead-real-time two-stage distributed robustoptimization scheduling model based on data driving. According to the invention, the absorption of renewable energy can be promoted, the absorption of biomass energy is promoted, the heat preservation and supply of the biogas digester can be realized in winter, and the stable supply of biogas is guaranteed; and the thermoelectric coupling degree is weakened, the consumption of wind-solar renewable energy sources is effectively promoted, and meanwhile, the comprehensive scheduling cost of the system is reduced.

Description

technical field [0001] The invention belongs to the technical field of integrated energy system optimization scheduling, and in particular relates to an energy hub-based biogas-wind-solar full renewable energy system and a method thereof. Background technique [0002] At present, the uncertainty of renewable energy output has brought great challenges to the development of renewable energy systems. Therefore, it is of great practical significance to construct a renewable energy system and study its optimal dispatching model, considering uncertain factors comprehensively. At present, many scholars have studied the integrated energy system with renewable energy based on the concept of energy hub, but have not constructed an energy hub coupling matrix for specific problems, so it cannot fully explain the legitimacy and rationality of using energy hub to analyze energy operation optimization problems In addition, such systems often contain conventional units, and no further rese...
