Method for evaluating energy production equipment configuration and load matching degree of comprehensive energy system

Abstract

The invention discloses a method for evaluating the energy production equipment configuration and load matching degree of a comprehensive energy system. The method comprises the following steps: S1, obtaining comprehensive energy system production equipment configuration data and load data in unit time; S2, acquiring the maximum load of the comprehensive energy system in unit time; S3, obtaining the minimum effective supply upper limit of the comprehensive energy system in unit time; wherein the minimum effective supply upper limit is the upper limit that the remaining comprehensive energy system equipment can supply energy when any power equipment, any energy storage equipment or any tie line in the comprehensive energy system cannot be utilized; S4, acquiring an evaluation index, and calculating the evaluation index according to the maximum load and the minimum effective supply upper limit of the comprehensive energy system in unit time; S5, judging whether the evaluation index is greater than a set value or not; if yes, ending; otherwise, alarming to prompt.

Description

technical field [0001] The invention belongs to the field of integrated energy (distributed energy), and in particular relates to a method for evaluating the matching degree of energy production equipment configuration and load in an integrated energy system. Background technique [0002] In the field of integrated energy (distributed energy), especially in gas-fired distributed energy systems, there is a common problem that equipment configuration and actual operating load cannot be accurately matched. The main reason for this problem is that the equipment configuration is matched according to the medium and long-term load forecast results of energy users in the project planning stage. It's hard to be precise. Once the project is completed, the supply capacity of energy production equipment is often higher / lower than the actual load demand, resulting in waste or shortage of equipment, which significantly affects the economy or safety of energy supply. [0003] At present,...

Problems solved by technology

[0004] In the industry, the experience of operating personnel usually evaluates the matching degree of equipment configuration and actual operating load from time to time. This requires very high skill requirements for operating personnel, and the experience of operating personnel has a certain lag compared to changes in actual load. Especially for integrated energy systems that contain a large amount of renewable energy and energy storage equipment, it is difficult for operators to make accurate judgments, which can easily affect the decision-making of equipment planning and construction, and even affect the security of energy supply in severe cases
