Optimized Scheduling of Biogas-photovoltaic-wind Rural Integrated Energy System Based on Energy Hub

The complex coupling between biogas and other renewable energy sources in the conversion and storage of multiple energy sources poses certain challenges to the development of rural integrated energy systems(RIES). Considering the uncertainty of load and renewable energy, as well as the grid structure of the power system, an optimal scheduling model for the biogas-photovoltaic-wind RIES base on the energy hub was established in this paper that considers both economy and environmental protection. The effectiveness and feasibility of the proposed optimal scheduling model can be verified through simulation analysis of a proposed RIES of Fujian Province. The simulation results show that increasing the feedback mechanism of energy hubs can promote multi-energy complementation, further promote the generation and consumption of renewable energy, and reduce the investment and operation costs of the biogas-photovoltaic-wind RIES; The optimized operation scheme obtained by considering multiple objectives of the economy and environmental protection can ensure low carbon emissions while reducing operation costs, providing a reference for the construction of RIES.
