摘要
不同于传统电网,能源互联网更有利于实现高比例可再生能源、促进资源高效合理配置。然而现有系统中多存在分布式能源管理与控制不够灵活高效等问题,为此本文提出了一种基于能源互联网中时隙对等的P2P能源共享和协调新框架。通过对于物理层分布式电源、分布式储能系统、智能电网的整合,构建P2P能源共享仿真环境。采用ADMM分布式优化算法,以系统经济性最优为目标进行建模求解。基于成都市某地真实数据集的数值仿真与分析可知,本方案相比于已有需求侧响应算法具有更快的收敛速度,并能有效提升整体经济性。
Different with traditional power grids,the Energy Internet is more conducive to achieving a high proportion of renewable energy and promoting efficient and reasonable allocation of resources.However,existing systems often have problems such as inflexible and efficient distributed energy management and control.For this reason,this paper proposes a new framework for P2P energy sharing and coordination based on time slot equivalence in the energy Internet.Through the integration of distributed power sources,distributed energy storage systems,and smart grids under physical layer,a P2P power transaction simulation environment is constructed.The ADMN distributed optimization algorithm is adopted,and the model is solved with the goal of optimal system economy.Based on the numerical simulation and analysis of the real data set in a certain place in Chengdu,it can be seen that this solution has a faster convergence rate than the existing demand-side response algorithm,and can effectively improve the overall economy.
