摘要

针对园区综合能源系统的多能耦合和零碳运行问题,提出一种考虑碳捕集和电转气的零碳园区综合能源系统经济调度策略。首先,分析园区综合能源系统架构,建立考虑碳捕集和电转气的电、热、冷、气多能耦合的园区综合能源系统模型;其次,综合核算园区生态碳汇、能源生产碳源等,提出适用于园区综合能源系统的零碳指标,以系统经济效益最优为目标建立零碳园区综合能源系统经济调度模型;最后基于不考虑碳中和约束、考虑碳中和约束及考虑碳捕集和电转气联合运行的3种场景,结合分时电价并采用改进粒子群算法对经济调度模型进行求解。结果验证了所提模型和方法的有效性,考虑碳捕集和电转气联合运行的方式可提高清洁能源的消纳率、降低系统运行的成本,同时实现园区综合能源系统的碳中和。

Abstract

Aiming at problems of multi-energy coupling and zero-carbon operation of park integrated energy systems, this paper proposes a zero-carbon economic dispatch strategy of integrated energy system of the park considering carbon capture and power-to-gas. Firstly, we analyze the architecture of the park integrated energy system to establish a comprehensive model that takes into account carbon capture and P2G coupled with electricity, heat, cooling and gas. Secondly, we conduct a comprehensive calculation of the park's ecological carbon sinks, energy production carbon sources, and other related factors. Zero-carbon indicators were proposed for the system, and an economic dispatch model was developed to maximize its economic benefits. Finally, based on three scenarios： economic dispatch ignoring carbon neutrality constraints, economic dispatch considering carbon neutrality constraints and economic dispatch considering CCUS-P2G joint operation, The improved particle swarm algorithm is used to solve the model combining time-of-use electricity prices. The results verify the effectiveness of the model and method proposed in this paper. Economic dispatch considering CCUS-P2G joint operation can improve clean energy absorption rates, reduce operating costs of the system, and achieve carbon neutrality in the park.
