The need for future sustainable energy and better transmission efficiency has advocated the large-scale integration of distributed energy resources (DER) in the utility network. The high penetration of DERs such as solar PV can potentially result in serious issues such as reverse power flow, voltage fluctuations, and utility revenue loss. The concept of a virtual power plant (VPP) can be a possible way to address these challenges through its coordinated operation of aggregated generation and flexible demand. The main goal of this research is to design the VPP model for the 11 kV distribution networks, which assists the utility in flattening its demand profile and permits high integration of grid-connected DER in a secure manner. In this study, the DER generation and load profiles of 11 kV feeders (residential and industrial) are simulated using the DER-CAM model. The results show that peak load on feeders is reduced by 37.25% and 42.78% with DER and combined DER and demand response, respectively. The solar tariff and combined operation of feeders facilitate the effective utilization of excess solar generation and prevent reverse power flow.

对未来可持续能源和更高传输效率的需求提倡在公用事业网络中大规模集成分布式能源 (DER)。太阳能光伏等分布式能源的高渗透率可能会导致严重的问题，例如逆潮流、电压波动和公用事业收入损失。虚拟发电厂 (VPP) 的概念可以通过其聚合发电和灵活需求的协调运行来应对这些挑战。本研究的主要目标是为 11 kV 配电网络设计 VPP 模型，该模型有助于公用事业公司扁平化其需求曲线，并允许以安全方式高度集成并网分布式能源。在这项研究中，使用 DER-CAM 模型模拟 11 kV 馈线（住宅和工业）的 DER 生成和负载曲线。结果表明，使用 DER 以及组合 DER 和需求响应，馈线的峰值负载分别降低了 37.25% 和 42.78%。太阳能电价和馈线的联合运行有利于有效利用多余的太阳能发电并防止逆潮流。
