含气热电联产及源荷侧双响应的综合能源系统低碳经济调度
摘要：为提高新能源的消纳能力，实现综合能源系统低碳、经济运行，提出一种气、热、电联产(combined gas, heat and power, CGHP )系统模型和一种考虑荷侧用能替代的综合能源系统源、荷侧协同运行策略。首先，根据电转气和碳捕集系统的运行特性，搭建CGHP系统模型的基本构架，围绕该基本架构，研究分析了CGHP系统的热电运行特性和电–气–热的量化关系。其次，根据源侧能源价格信息，建立碳交易机制下负荷间替代转换的综合需求响应模型。最后，在保证用户用能满意度的前提下，以综合能源系统日运行成本最低为目标，合理安排系统源、荷侧的调度计划。算例结果表明，所提模型和运行策略具备可行性和有效性，为促进综合能源系统消纳新能源、降低CO2排放和系统日运行成本等方面提供了参考。
Abstract:To improve the absorptive ability of new energy and realize low-carbon and economic operation of integrated energy system, a combined gas, heat and power (abbr. CGHP) system model and coordinated operation strategy of the source-load sides considering the substitution of energy on the load-side was considered. Firstly, according to the operating characteristics of power to gas (abbr. P2G) and carbon capture system, a basic frame of CGHP system model was built to research and analyze the thermoelectric operation characteristic of CGHP system and the quantitative relation of electricity-gas-heat. Secondly, according to the source-side energy price information, an comprehensive demand response model for the substitution and transformation among loads under the carbon trading mechanism was established. Finally, under the premise of ensuring the satisfaction with users’ energy consumption, taking the minimized daily operating cost of integrated energy system as the objective, a dispatching plan at the source-load side of the grid was reasonably arranged. The results of the computing example show that the proposed model and operation strategy are feasible and effective, and can provide some references for promoting the integrated energy system to absorb new energy, decreasing the emission of CO2 and reducing daily operating cost of the system.
