Problems solved by technology

However, the traditional planning method is only aimed at a single energy system, and the planning problem of the joint energy supply system needs to be solved urgently.
However, in the traditional planning method, due to the low degree of correlation between the two systems, usually only a single energy supply system is specially planned and optimized, which may cause problems such as repeated investment in equipment and low utilization rate, reducing the cost of energy supply. economy

Embodiment Construction

[0066] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0067] like figure 1 As shown, the present invention provides a collaborative planning method for a combined gas-electricity system, comprising the following steps:

[0068] S1 Considering the safety constraints of the power system, the safety constraints of the natural gas system and the constraints of gas-electricity coupling are also considered, and a collaborative planning model for the combined gas-electricity system is established;

[0069] S2 Comprehensively consider the economy and environmental protection of the planning scheme, and determine the optimal construction scheme for natural gas pipelines and power lines;

[0070] S3 builds a calculation example of the joint energy supply system to test the correctness of the proposed method.

[0071] In step S1, compared with the traditional power grid planning, the collaborative planni...

Abstract

The invention relates to a collaborative planning method of a gas-electric combined system, which comprises the following steps of: 1) establishing a collaborative planning model of the gas-electric combined system by considering both the safety constraint of a power system and the safety constraint and gas-electric coupling constraint conditions of a natural gas system; And 2) taking the planningscheme of the gas-electric combined system as particles, solving the collaborative planning model of the gas-electric combined system by adopting a particle swarm algorithm, and obtaining an optimalplanning scheme of the natural gas pipeline and the power line, namely the number of newly-built pipelines and lines on each pipeline and line corridor. Compared with the prior art, the method has theadvantages of environmental protection, search performance enhancement, good planning effect and the like.

Description

technical field [0001] The invention relates to the field of combined gas-electricity energy supply systems, in particular to a collaborative planning method for the combined gas-electricity system. Background technique [0002] With the continuous increase of natural gas consumption and the increase of the proportion of natural gas power generation, the connection between natural gas system and electric power system is getting closer. However, the traditional planning method is only for a single energy system, and the planning problem of the joint energy supply system needs to be solved urgently. However, in the traditional planning method, due to the low degree of correlation between the two systems, usually only a single energy supply system is specially planned and optimized, which may cause problems such as repeated investment in equipment and low utilization rate, reducing the cost of energy supply. economy. In this context, on the basis of the existing research resu...
