摘要
随着电-气-热综合能源系统(IES)内多类型能源转换设备广泛接入,热网动态特性对系统运行影响日益显著,能源低碳转型战略的实施使得碳排放成为IES运行关注的焦点之一。对此,文章开展考虑热动态和碳交易的电-气-热IES协调调度的研究。基于动稳态模型构建的供热网络潮流结果,研究其动稳态差异;进一步面向当前碳交易市场发展需求在IES运行中考虑碳交易,构建以购能成本、运行成本及碳交易成本等综合成本最低为目标的电-气-热IES协调调度模型,从多环节挖掘节能减排潜力;构建算例系统进行仿真分析,结果表明,考虑热动态特性和碳交易的IES多网络耦合协调调度,能量跨时空转移特征明显,且有效降低碳排放,实现其能源综合、高效利用的目标。
With the widespread access to multiple types of energy conversion equipment within the electricity-gas-heat integrated energy system(IES), the dynamic characteristics of the heat network have an increasingly significant impact on the system operation, and the implementation of the energy low-carbon transition strategy has made carbon emissions become one of the focal points of IES operation concerns. In this regard, we conduct a research on the coordinated scheduling of electricity-gas-heat IES considering thermal dynamics and carbon trading. Firstly, we study the dynamic-stable differences of the heating network based on the trend results constructed by the dynamic-stable model;furthermore, we consider carbon trading in the IES operation in view of the current development demand of carbon trading market, and construct a coordinated electricity-gas-heat IES scheduling model with the objective of minimizing the comprehensive costs of energy purchase cost, operation cost and carbon trading cost, etc. Finally, the simulation results show that the IES multi-network coupled coordinated scheduling considering thermal dynamic characteristics and carbon trading has obvious energy transfer characteristics across time and space, and effectively reduces carbon emissions to achieve its goal of comprehensive and efficient energy utilization.
