摘要:

随着光伏渗透率和用户用电量的不断提高,配电网经常出现源荷功率差异大的情况,进而导致部分节点电压上、下界严重越限问题,既增加电网功率和电能损耗,又影响用户正常用电。从配电系统供需平衡角度出发,构建了一种虚拟电厂和配电网的协同调度模型,利用虚拟电厂能聚合多种分布式能源的特性,通过提供虚拟电厂的有功/无功功率使其有效参与到配电市场的运行中,改善电压上、下界越限问题,提高电能质量和配电系统的安全可靠性,同时降低了配网总运行成本。仿真结果表明,构建的协同调度模型通过利用虚拟电厂的灵活性,有效缓解了配电网的电压上、下界越限问题,配电网总运行成本降低,安全稳定性能得到了提升。

Abstract:

With the continuous increase in photovoltaic penetration and user electricity consumption, serious upper and lower voltage limit violations often occur at partial nodes of distribution networks due to significant power imbalances between the source side and the user side, which not only increases the power and energy loss of the grid, but also affects the normal electricity consumption of users. This study developed a coordinated dispatch models between virtual power plants (VPPs) and distribution networks from the perspective of supply-demand balance in power distribution systems. By leveraging the capability of VPPs to aggregate diverse distributed energy resources (DERs), the models enable VPPs to actively participate in distribution market operations through the provision of active and reactive power support. This approach effectively mitigates both the upper and lower voltage limit violations, thereby enhancing power quality and the security/reliability of the distribution systems, while simultaneously reducing the total operational costs of the grid. Simulation results demonstrate that the coordinated dispatch models developed in this paper effectively alleviate the upper and lower voltage limit violations in distribution networks by utilizing the flexibility of VPPs, reduce the total operating cost and enhance the overall safety and stability performance of the distribution networks.

Key words: distributed energy storage, distributed photovoltaic, distribution network, virtual power plant, voltage limit violation
