摘要
为进一步挖掘能源互联网多能源互补的潜力,提高能源系统的运行收益,降低运行成本,提出了一种考虑消纳效益的多能源枢纽荷源协调优化方法。考虑多能源系统的约束条件,依据最小化住宅能量枢纽运行总成本构建住宅能量枢纽模型,以最大化工业能量枢纽运行总收益为目标构建工业能量的枢纽模型。根据上述两层模型的约束条件得到荷源协调优化运行中存在的问题,采用多目标加权寻优算法,设计多目标混合整数线性规划模型,实现荷源协调优化。仿真实验结果表明:所设计的考虑消纳效益的多能源枢纽荷源协调优化方法可促进可再生能源的消纳,降低多能源枢纽的运行成本,有效减少开销,提高能源系统的运行收益,为多能源枢纽的经济运行及荷源协调优化提供了新的技术途径。
In order to further tap the potential of multi-energy complementarity of energy Internet,improve the operating income of energy system and reduce the operating cost,an optimization method of load-source coordination of multi-energy hub considering consumption benefit was proposed.Considering the constraints of multi-energy system,the residential energy hub model was constructed according to minimizing the total operating cost of residential energy hub,and the industrial energy hub model was constructed with the goal of maximizing the total operating income of industrial energy hub.According to the constraints of the above two-layer model,the problems existing in the coordinated optimization of load and source are obtained,and the multi-objective mixed integer linear programming model was designed by using the multi-objective weighted optimization algorithm to realize the coordinated optimization of load and source.The simulation results show that the designed optimization method of load-source coordination of multi-energy hub considering consumption benefit can promote the consumption of renewable energy,reduce the operating cost of multi-energy hub,effectively reduce the overhead and improve the operating income of energy system,which provides a new technical way for the economic operation and load-source coordination optimization of multi-energy hub.
