摘要/Abstract

摘要： 综合能源系统作为推动能源结构绿色低碳转型的重要手段，可通过广义储能（柔性负荷和传统储能的组合）实现多能互补和高比例可再生能源的消纳。然而在综合能源系统的削峰填谷能力和经济性影响方面，广义储能缺乏量化的效益研究。本文构建了计及广义储能的建筑产消者社区综合能源系统，并针对广义储能提出了削峰填谷能力和经济性的评价指标。以综合能源系统日前运行调度经济性最优为目标，利用MATLAB中的Yalmip工具箱和Gurobi求解器对4种不同优化情景算例进行求解，对比分析了传统储能，柔性负荷和广义储能对建筑产消者社区综合能源系统的削峰填谷能力和经济性的影响。优化结果表明，采用广义储能可降低建筑产消者社区综合能源系统的日运行费用达24.0%。计及广义储能的综合能源系统的削峰填谷能力和经济性优于传统储能，且柔性负荷调节的经济性相比传统储能的更具优势，但在补偿价格较高的情况下，柔性负荷调节反而可能不如传统储能。

Abstract: As an important approach for green and low-carbon transformation of the energy structure, integrated energy systems can achieve multi-energy complementarity and high-ratio renewable energy penetration through generalised energy storage (i.e. combination of flexible loads and traditional energy storage). However, there is a lack of quantitative investigation on the benefits of using generalised energy storage in integrated energy systems, from the aspects of load-shifting capability and costs. This paper presents the establishment of an integrated energy system employing generalised energy storage for a building prosumer community and proposes the assessment factors of load-shifting capability and economic benefits for generalised energy storage. A day-ahead economic dispatch optimisation of the integrated energy system was formulated with the objective of maximising the operational economic benefits. Four optimisation scenarios were designed to comparatively investigate the contributions of traditional energy storage only, flexible loads only, and both generalised energy storage approaches to the load-shifting capability and economic benefits of the proposed system. The optimisation scenarios were resolved using the Yalmip toolbox and Gurobi solver in MATLAB. The optimisation results show that the operational costs of the integrated energy system can be reduced by 24.0%, when employing the generalised energy storage. Both the load-shifting capability and economic benefits achieved when using the generalised energy storage outperformed those using the traditional one, and the flexible load management contributed to the economic benefit more significantly than that adopting traditional energy storage. However, in the case of high compensation price, the economic benefits of flexible load management may be worse than that of traditional energy storage.
