摘要: |
基于电动汽车(EV)入网和电池储能系统(BESS)模块化封装设计特点,研究并网型微网的EV能量管理、BESS优化配置和运行。制定2种电价引导机制,建立EV有序充电和有序充放电管理模式;离散化节点上 BESS安装容量,考虑BESS荷电量时段间耦合约束,以一日内BESS投资成本和微网运行成本之和最小为目标,构建BESS选址定容模型。分别运用直流最优潮流(DCOPF)法和交流最优潮流(ACOPF)法,并采用KNITRO求解器计算该混合整数非线性规划(MINLP)问题。仿真结果表明:ACOPF方法可精确配置BESS模块数量和位置;相比EV有序充电,有序充放电模式可显著减少BESS配置容量;激励EV参与孤岛,可提高备用容量充裕度,增强微网运行可靠性。 |

Abstract: |
Based on the grid-connection of EVs(Electric Vehicles) and the modular design of BESS(Battery Energy Storage System),the energy management of EV and the optimal allocation and operation of BESS are researched for the grid-connected microgrid. Two kinds of electricity price guide mechanism are introduced,and the coordinated EV charging mode and the coordinated EV charging & discharging mode are established. The installed capacity of nodal BESS is discretized,and a sizing and siting model of BESS is built,which takes the minimum sum of daily BESS investment cost and operational cost as its objective and considers the BESS energy constraint coupled between adjacent intervals. With the KNITRO solver,the DCOPF(Direct Current Optimal Power Flow) method and the ACOPF(Alternating Current Optimal Power Flow) method are applied respectively to solve the MINLP(Mixed Integer NonLinear Programming) problem. Simulative results show that,the ACOPF method can accurately configure the modular quantity of BESS and their sites,the BESS capacity needed in the coordinated EV charging & discharging mode is dramatically smaller than that in the coordinated EV charging mode,the participation of EV in the islanded microgrid can enhance the redundancy of reserve capacity and the reliability of microgrid operation. |
