Problems solved by technology

Due to the abundance of rural biomass resources and the advantages of zero carbon, its development has received widespread attention. Some studies have used the planning method of the above-mentioned integrated energy system to plan the rural energy system in order to improve the economical operation of the system. However, currently, for traditional integrated energy The systematic planning method does not consider the characteristics of rural energy systems. Therefore, it is necessary to propose a coupling element planning method suitable for rural energy systems to promote rural economic development in view of the characteristics of small-scale rural energy systems and abundant biomass resources.

Abstract

The invention discloses a rural electric heating combined system coupling element planning method. The method comprises the following steps: firstly, establishing a mathematical model of a rural electric heating combined system; secondly, determining a scheme candidate set for planning the coupling element of the rural combined electric heating system according to a system structure and topology; then selecting indexes for measuring the advantages and disadvantages of schemes in the candidate set according to actual requirements of engineering, and calculating energy flow distribution of the combined system by utilizing multi-energy flow load flow calculation of the combined electric heating system; and solving a measurement index according to a multi-energy flow load flow calculation result to determine a final planning scheme. Aiming at the characteristics of small scale and abundant biomass of a rural energy system, the invention provides a coupling element planning method which is more suitable for rural practical problems than an existing method, the application potential of multi-energy flow load flow calculation in planning problems is fully utilized, the application of biomass energy in rural areas is promoted, and the operation economy of the rural energy system is improved.

Description

technical field [0001] The invention belongs to the field of electrical engineering, and in particular relates to a planning method for coupling elements of a combined electric heating system in rural areas. Background technique [0002] With the depletion of fossil fuels and environmental pollution, renewable energy such as wind energy and solar energy is developing rapidly. However, renewable energy is uncertain and intermittent, and it is difficult for the power system to make full use of it. Therefore, to improve energy utilization Efficiency, discovery of new energy sources, and realization of large-scale development of renewable energy sources have become inevitable choices to resolve the contradictions between energy demand growth, energy shortage, and environmental protection. [0003] The integrated energy system breaks the existing mode of separate planning, separate design and independent operation of various energy supply systems such as electricity, heat, and ga...
