摘要 推动新能源汽车产业规模化发展是实现交通和多能源系统低碳转型的重要途径,为保障系统供能可靠性与碳减排能力的提升,该文构建了计及供能可靠性动态约束与碳减排的充能型微网互联系统优化模型。首先,研究各微电网的运行特性以及微电网间的能量交互特性,建立低碳充能型多能源微网互联系统(MCMIS-LCEs)模型,并在此基础上建立多能源供能与碳减排协调模型;其次,考虑能源转换、存储与充能设备故障对MCMIS-LCEs供能可靠性的动态影响,针对设备故障特点建立多状态可靠性动态量化评估模型;然后,在互联系统供能可靠性约束、运行约束等条件下,建立考虑碳减排、充能时间与供能成本协同的MCMIS-LCEs多目标优化模型;最后,基于充能站实际能源与车流量数据进行算例的仿真验证。结果表明,该文提出的MCMIS-LCEs及其优化模型能够实现多能源转换、存储与充能设备间的高效协调,提升整体互联系统的经济性、碳减排能力、垃圾处理能力、电网调节能力,以及充能供能可靠性。

Abstract:Promoting the large-scale development of the new energy vehicle industry is an important way to realize the low-carbon transformation of transportation and multi-energy systems. In order to ensure the improvement of system energy supply reliability and carbon emission reduction capability, an optimization model of charging microgrid interconnection system considering dynamic constraints of energy supply reliability and carbon emission reduction was constructed in this paper. Firstly, the operation characteristics of each microgrid and the energy interaction characteristics between microgrids are studied, and the model of the multi-energy charging microgrids interconnection system with low carbon emissions(MCMIS-LCEs) was established. On this basis, a multi-energy supply and carbon emission reduction coordination model was established; Secondly, considering the dynamic impact of energy conversion, storage and charging equipment failures on the energy supply reliability of the MCMIS-LCEs, a multi-state reliability dynamic quantitative evaluation model was established according to the characteristics of equipment failures; Then, under the conditions of energy supply reliability constraints and operation constraints of interconnected systems, a multi-objective optimization model of the MCMIS-LCEs considering carbon emission reduction, charging time and energy supply cost coordination was established; Finally, simulation verification is performed based on the actual energy and vehicle flow data of the charging station. The simulation results demonstrate that the MCMIS-LCEs and its optimization model proposed in this paper can realize the efficient coordination between multi-energy conversion, storage and charging equipment, and improve the economy, carbon emission reduction capacity, waste process capacity, grid regulation capacity, and the reliability of energy supply of the whole interconnected system.
