摘要
大规模电动汽车(Electric Vehicles, EV)无序充电行为将增加电力系统运行的安全隐患,而数量庞大的电动汽车充放电优化控制为电力系统能量管控提出了新的挑战。提出一种改进的基于多代理系统(Multi-AgentSystem,MAS)的电动汽车充放电分布式协同调度方法。该方法以负荷填谷为目标,在虚拟电价协同机制框架下,综合考虑了配电网三相负荷平衡、变压器容量约束和节点电压约束,与MAS信息交互机制相结合,通过采用迭代修正虚拟电价的方法,实现EV有序的智能充放电。以IEEE33节点系统为例进行仿真分析,验证了所提方法的特点和有效性。
The large-scale Electric Vehicles(EV)uncontrolled charging behavior will increase the safety hazard of the power system operation,and a large number of EV charging and discharging control brings new challenge to energy management of the power system.In this paper,an improved EV charging and discharging distributed coordination dispatch control strategy based on Multi-Agent System(MAS)is proposed.It aims at the valley-filling,under the framework of the virtual price coordination mechanism,considers the distribution network three-phase balance,transformer capacity and node voltage constraint,and combining with MAS information interaction mechanism,adopts iterative correction of virtual price to achieve the intelligent charging and discharging of EV.Taking IEEE33 node system as an example,simulation and analysis verify the characteristics and effectiveness of the proposed method.
