Embodiment Construction

[0066] Herein, the detailed content and technical description of the present invention will be further described with a preferred embodiment, but it should not be construed as a limitation to the implementation of the present invention.

[0067] In order to realize the equipment configuration optimization (configuration strategy) of the integrated energy system, the present invention proposes the following requirements for the equipment configuration optimization:

[0068] 1) Equipment configuration optimization needs to consider the uncertainty of comprehensive demand response;

[0069] 2) The optimization of equipment configuration needs to consider the impact of electricity price on the load curve;

[0070] 3) Equipment configuration optimization needs to aim at reducing system investment and operating costs to ensure the minimum operating costs of the system under different electricity price scenarios.

[0071] 4) The optimization of equipment configuration needs to consi...

Abstract

The invention discloses an optimal configuration method and system for comprehensive energy system equipment. According to the optimal configuration method, the uncertainty of a price scheme and comprehensive demand response is comprehensively considered; an IES collaborative planning model considering IDR uncertainty is provided to realize optimal configuration of comprehensive energy system equipment; the method comprises the following steps: S1, making an electricity price scheme, calculating an IDR considering uncertainty according to the electricity price, obtaining a trust interval of the IDR through an evidence theory, and fitting a load curve based on a trust level constraint; s2, establishing a double-layer collaborative planning model considering equipment optimization configuration and an IES operation strategy on the basis of the electricity price scheme and the load curve; and S3, comparing the total cost of the IES under different electricity price schemes through the double-layer collaborative planning model to obtain an optimal electricity price scheme and an IES optimal configuration result.

Description

technical field [0001] The invention belongs to the field of integrated energy systems, and in particular relates to an integrated energy system equipment optimization configuration method taking into account the uncertainty of integrated demand response. Background technique [0002] Developing an integrated energy system (IES) to realize the organic coordination and optimization of various energy production, conversion, storage and consumption links has become an important means to promote energy transformation and build a clean, low-carbon, safe and efficient modern energy system. . IES optimization planning is the basis for accomplishing this goal. With the increase of energy coupling, storage, conversion and alternative equipment types, the maturity of market mechanism and the improvement of user participation, IES optimal configuration has become a complex and urgent problem to be solved. [0003] At present, the research on IES planning can basically be divided into ...
