摘要:

带电动汽车充电站的社区综合能源系统(CIES)为解决日益增长的能源效率和环境污染问题提供了新的途径,协调灵活的需求响应和多种可再生能源的不确定性是一项关键任务。为此,本文建立了一个新的双层优化调度模型的CIES与EVCS在多利益相关者的场景。在该模型中,一个综合的需求响应计划的目的是促进能源供应和需求之间的平衡,同时保持用户的综合满意度在可接受的范围内。为进一步挖掘需求响应潜力,灵活引导用户能源消费和电动汽车行为(充电、放电和提供旋转储备),提出了分时电价和实时电价相结合的动态电价机制。在求解阶段,利用序列运算理论(SOT),将原机会约束规划(CCP)模型转化为一个易于求解的混合整数线性规划(MILP)模型,并利用CPLEX求解器进行求解。对华北地区一个实际的CIES的仿真结果表明,该方法通过协调灵活的需求响应和不确定的可再生能源,实现了CIES和EVCS之间的利益平衡。

英文摘要:

A community integrated energy system (CIES) with an electric vehicle charging station (EVCS) provides a new way for tackling growing concerns of energy efficiency and environmental pollution, it is a critical task to coordinate flexible demand response and multiple renewable uncertainties. To this end, a novel bi-level optimal dispatching model for the CIES with an EVCS in multi-stakeholder scenarios is established in this paper. In this model, an integrated demand response program is designed to promote a balance between energy supply and demand while maintaining a user comprehensive satisfaction within an acceptable range. To further tap the potential of demand response through flexibly guiding users' energy consumption and electric vehicles' behaviors (charging, discharging and providing spinning reserves), a dynamic pricing mechanism combining time-of-use and real-time pricing is put forward. In the solution phase, by using sequence operation theory (SOT), the original chance-constrained programming (CCP) model is converted into a readily solvable mixed-integer linear programming (MILP) formulation and finally solved by CPLEX solver. The simulation results on a practical CIES located in North China demonstrate that the presented method manages to balance the interests between CIES and EVCS via the coordination of flexible demand response and uncertain renewables.
