| 摘 要： | 光伏电源的大规模并网可能致使配电网电压越限,受调压设备调压能力的限制,从网源侧角度考虑的调压方法易出现调压效果不理想的情况。针对光伏电源并网引起的配电网电压越限问题,通过对负荷侧电动汽车进行建模并分析其入网对配电网电压的影响,在一定情况下,将其作为可调度资源与光伏电源配合以控制配电网电压。通过考虑电动汽车用户需求响应,以各可控资源的优化控制成本最小为目标,建立了电动汽车与光伏电源联动的配电网电压调控模型,并对其进行优化求解以实现配电网内能源资源的最优利用,减小系统电压波动。算例分析中根据不同气象条件构建了两个场景,分析结果均验证了该策略的有效性。

| Abstract: | The voltage variation of the distribution network caused by the large-scale grid connection of photovoltaic power supply may exceed the limit. Due to the limitation of the capability of the voltage regulation equipment, the voltage regulation method on the network source side is not satisfied. Against the voltage beyond limit of the distribution network caused by grid-connected photovoltaic power supply, the electric vehicle model on the load side is established and the influence of its network access is analyzed. The voltage of the distribution network can be controlled by the cooperation of the schedulable electric vehicle resource and photovoltaic under certain circumstances. By considering the demand response of electric vehicle users and aiming at the optimal control cost of each controllable resource, the voltage regulation model of the distribution network linked by electric vehicle and photovoltaic power source is established and solved to achieve optimal utilization of energy resources in the distribution network, reducing voltage fluctuations. In the analysis of the example, two optimization scenarios are constructed according to different meteorological conditions, and the effectiveness of the strategy is verified. |
