Method for establishing comprehensive energy planning and operation joint optimization model

Abstract

The invention discloses a method for establishing a comprehensive energy planning and operation joint optimization model, which comprises the following steps of: unifying park equipment type selectionand operation scheduling optimization, performing joint optimization, and selecting an investment planning scheme with better economy by taking the minimum annual comprehensive cost as a target function. Equipment model selection is carried out in the planning stage, different types of equipment are mutually combined to form different planning schemes, and alternative planning schemes meeting theload standard are screened out by taking meeting the maximum load requirement of the park as a hard condition; in the operation optimization stage, for each alternative planning scheme, optimizationcalculation is carried out according to different equipment capacity configurations; and finally, comprehensively considering the cost expenditure situation in the planning and operation process, andselecting an investment planning scheme with better economy by taking the minimum annual comprehensive cost as a target function. According to the method, comprehensive energy system planning and operation control are associated, so that park operation optimization is more comprehensive and reasonable, and a planning operation scheme with better economic indexes is obtained.

Description

technical field [0001] The invention belongs to the technical field of electric power energy comprehensive system, and more specifically relates to a method for establishing a joint optimization model of comprehensive energy planning and operation. Background technique [0002] Under the background of electricity marketization, power supply companies cannot operate profitably only through the price difference between purchase and sale of electricity, and the existence of other competitors will lead to diversion of users. In order to attract users and increase user viscosity, power companies also need to provide value-added services closely related to power consumption. The "Administrative Measures" issued by the National Energy Administration clarifies the scope of value-added services provided by power companies, mainly including but not limited to energy-saving planning, personalized bills, energy equipment operation and maintenance, and comprehensive energy services. Int...

Problems solved by technology

[0004] In order to solve the problem that most of the current studies on the planning and operation of the integrated energy system park are independent of each other, it is impossible to make the park operation optimization more comprehensive and reasonable, so as to obtain an investment planning plan with better economic indicators, and proposes a comprehensive The joint optimization model establishment method of energy planning and operation unifies the park equipment selection, energy supply network optimization and operation scheduling optimization for joint optimization
