摘要:

微能源网能够提供冷、热、电等多类型能源,使多种能源的综合调度成为可能。从数量与质量两方面反映系统中不同能源的利用效率。为了提高能源利用率,基于以热力学第二定律为基础的理论,进行了全系统的整体性分析,建立了以效率最大为优化目标的微能源网调度模型,并利用算例验证了所提出的优化调度模型能准确地揭示能量的利用程度,实现能量评价指标从数量特征到品质特征的转变。

Abstract:

Micro energy grid can provide multiple types of energy such as cold,heat,and electricity,making it possible to integrate and dispatch the various kinds of energy resources.Exergy analysis shows the efficiency of different types of energy in two aspects of quantity and quality.Based on the exergy theory on the basis of the second law of thermodynamics,this paper analysed exergy of the whole system and then established a micro energy grid scheduling model with exergy efficiency maximization as the optimization goal in order to improve energy utilization,and solve the model with particle swarm optimization algorithm.Using an example to verify the proposed optimization scheduling model can reveal the utilization of energy accurately,and realize the transformation of energy evaluation index from quantity characteristic to quality characteristic.

Key words: micro energy grid, energy utilization rate, efficiency, optimal dispatch, particle swarm optimization
