摘要: |
电动汽车充电时间灵活、调控性能好,可作为一种可控负荷参与微电网的负荷调节,从而避免微电网孤岛运行时发电量不足而切负荷。基于此,重点研究了计及电动汽车充电控制策略的微电网可靠性分析。首先,建立了电动汽车最小高峰负荷模型,以评估微电网孤岛运行时电动汽车的调控潜力。紧接着,基于最小高峰负荷模型,提出了计及供电可靠性的电动汽车-储能联合调控策略。然后,基于蒙特卡洛模拟法,提出了计及电动汽车-储能联合调控策略的微电网可靠性评估方法。最后,通过改进的RBTS Bus6 F4馈线系统进行算例仿真。仿真结果验证了所提模型和策略的有效性。算例结果表明,所提的微电网调控策略能在满足电动汽车充电需求的基础上,有效降低电动汽车接入对微电网可靠性的影响。 |

Abstract: |
The electric vehicle has flexible charging time and good regulation performance. As a controllable load, the electric vehicle can participate in the load regulation of the microgrid, thereby avoiding the removal of the load due to insufficient power generation during the operation of the micro-grid island. This paper focuses on the reliability analysis of microgrids that take into account the charging control strategy of electric vehicles. Firstly, the minimum peak load model of electric vehicles is established to evaluate the regulation potential of electric vehicles in the microgrid operation period. Secondly, based on the minimum peak load model, an electric vehicle-energy storage joint regulation strategy considering power supply reliability is proposed. Thirdly, based on the Monte Carlo simulation method, a microgrid reliability assessment method considering the electric vehicle-energy storage combined regulation strategy is proposed. Finally, a numerical simulation is carried out through the modified RBTS Bus6 F4 feeder system. Simulation results verify the effectiveness of the proposed model and strategy. The results of the example show that the proposed microgrid regulation strategy can effectively reduce the impact of large-scale electric vehicle access on the reliability of microgrid on the basis of meeting the charging demand of electric vehicles.
