Problems solved by technology
The entropy weight method is an objective weighting method, but the sensitivity to the index difference is too high, which may easily lead to extreme situations in the weight distribution. When the index weight is too small, the meaning of the evaluation index will be lost.

The invention discloses an electro-gas region comprehensive energy system elasticity evaluation method based on a hetero-dependency network, and the method comprises the steps: 1), building an electro-gas region comprehensive energy system elasticity index system from two dimensions, i.e., vulnerability and resilience, of elasticity for an extreme event by establishing five indexes for quantifyingthe elasticity of the electro-gas region comprehensive energy system, and defining each elastic index in a complex form; 2) establishing a heterogeneous dependency network model of the electro-gas region comprehensive energy system, converting the heterogeneous dependency network model into a double-layer two-way diagram, and calculating values of five indexes; and 3) determining weights of the five indexes by using a geometric average G1-anti-entropy weight method, and calculating to obtain a comprehensive elastic value of the system, thereby realizing elastic evaluation of the comprehensiveenergy system in the electro-gas region. According to the method, the dependence and heterogeneity of a power network and a natural gas network are considered, fault propagation analysis is facilitated, meanwhile, the subjective and objective weights of indexes are considered, and the elasticity of the comprehensive energy system in the electro-gas area can be scientifically and effectively quantified and evaluated.
Description
technical field [0001] The invention relates to the technical field of comprehensive energy system engineering, in particular to a method for evaluating the elasticity of an electric-gas regional comprehensive energy system. Background technique [0002] According to the spatial scale and system scale, the integrated energy system (IES) mainly includes three types: cross-regional, terminal, and regional integrated energy systems. The electricity-gas regional integrated energy system is composed of electric power system, natural gas system and energy center, which mainly realizes the complementary support between distribution network, gas distribution network, regional energy center and other regional energy systems within the region. Resilience includes the ability to resist and recover from deliberate attacks, accidents, and naturally occurring threats or events. In the electricity-gas regional integrated energy system, the distribution network is located at the end of the...
