Problems solved by technology
[0003] Most of the current research on integrated energy systems focuses on the transmission side of power networks, heat networks, and natural gas networks, while the research on the distribution side is relatively immature, and the optimization and planning of integrated energy systems are more important. Imperfect, so the integrated energy system that exists on the power distribution side still needs more systematic and specific research to improve energy utilization

The invention discloses a configuration method for a distributed power supply in a comprehensive energy system. The method comprises the following steps: (10) building a power network model, a thermodynamic network model and a distributed power supply model respectively; (20) carrying out thermoelectric coupling on a power network and a thermodynamic network through the distributed power supply according to the models built in the step (10), and building a comprehensive energy system model; and (30) determining the comprehensive energy system model built in the step (20) by a particle swarm algorithm and obtaining configuration of the distributed power supply in the comprehensive energy system. The configuration method ensures that the system efficiently meets multi-energy requirements, provides the optimal configuration of the system within a year scale range, and simultaneously improves the operation economy of the comprehensive energy system.
Description
technical field [0001] The invention belongs to the field of comprehensive energy systems, and in particular relates to a method for configuring distributed power sources in the comprehensive energy system. Background technique [0002] At present, the urgent requirements for economic and environmental issues have promoted the further development of a sustainable society. Therefore, independent network structures can no longer meet the growing demand for diversified energy sources (such as natural gas, electricity, heat and other energy forms). Traditionally, the result of separate optimization of the network is often unable to accurately implement a precise scheduling plan for the joint network, while the integrated energy system is more adaptable to the needs of various energy forms due to the interconnection and coupling of energy, so the planning results are more accurate. precision and reliability. [0003] Most of the current research on integrated energy systems focu...
