摘要
为解决交流配电网电能传输效率低下等问题,以融合中压与低压层级的交直流混合配电网为基础,提出了一种基于中低压交直流配网的综合能源系统配置方法,同时还能提高新能源消纳能力与供电可靠性。首先,建立综合能源服务设备配置和日常运行经济性双层规划模型;然后,通过改进飞蛾火焰优化算法与CPLEX进行联合求解;最后,在给定算例下得到最优的综合能源设备配置方案,并与传统交流配电网下的各项成本进行对比分析,验证了基于交直流配电网的综合能源系统更具有先进性与可靠性。
In order to solve the problems of low power transmission efficiency in AC distribution network,a comprehensive energy system configuration method is proposed based on AC/DC hybrid distribution network that integrates medium voltage and low voltage levels,which can improve the new energy consumption capacity and power supply reliability.Firstly,a two-level programming model of integrated energy service equipment configuration and daily operation economy is established.Then,the improved moth flame optimization algorithm is combined with CPLEX to solve the problem.Finally,the optimal integrated energy equipment configuration scheme is obtained under the given example,and the various costs under the traditional AC distribution network are compared and analyzed,which proves that the integrated energy system based on the AC/DC distribution network is more advanced and reliable.
