【摘要】：随着能源与电力领域供给侧改革的推广,以电力为主体并融合天然气、热能和交通等多种能源形式的区域综合能源系统将成为未来城市配网的主要发展趋势。利用能源集线器模型刻画了同时耦合于电力网、天然气网和交通网的终端综合能源单元,利用能源转化特性提出了面向供给侧改革的综合能源供给转化响应策略,并且基于终端综合能源单元和供给转化响应策略提出了兼顾系统建设运行成本、慢充站充电时间效用函数和快充站交通流量效用函数的综合能源城市配网规划方法。最后,以一个由IEEE 14节点配电网络、20节点天然气网络和25节点交通网络耦合而成的区域综合能源系统为例进行仿真分析,验证了该规划方法所采用的充电站双重效用函数可分别保障电动汽车用户的充电时间满意度和充电地点便捷度,所利用的供给转化响应策略能通过调整能源供给结构实现在不改变负荷需求的前提下降低用能成本、优化运行特性的目的,同时所引入的基于终端综合能源单元的规划格局可实现电能、天然气、热能和交通等多元能源形式的统一协调规划,有利于提高系统建设运行的综合效益。
[Abstract]:With the promotion of supply-side reform in the field of energy and power, the regional integrated energy system, which takes power as the main body and integrates natural gas, thermal energy and traffic, will become the main development trend of urban distribution network in the future. The terminal integrated energy unit coupled to power network, natural gas network and transportation network is described by using the energy hub model. The response strategy of integrated energy supply conversion oriented to supply-side reform is proposed by using the energy conversion characteristics. Based on the terminal integrated energy unit and supply conversion response strategy, a comprehensive energy distribution network planning method is proposed, which takes into account the system construction cost, charging time utility function of slow charging station and traffic flow utility function of fast charging station. Finally, a regional integrated energy system, which is coupled with IEEE 14-bus distribution network with 20-node natural gas network and 25-node transportation network, is simulated and analyzed. It is verified that the dual utility function of charging station used in this planning method can guarantee the satisfaction of charging time and the convenience of charging location, respectively. By adjusting the energy supply structure, the response strategy can reduce the cost of energy use and optimize the operation characteristics without changing the load demand. At the same time, the planning pattern based on terminal integrated energy unit can realize the unified and coordinated planning of multiple energy forms, such as electric energy, natural gas, heat energy and traffic, which is helpful to improve the comprehensive benefit of system construction and operation.
