当前虚拟电厂（virtual power plant，VPP）建设方兴未艾。虚拟电厂参与电网调度需要综合考虑虚拟电厂运营商的经济性要求与电网的安全性要求，但在目前的电力系统信息安全要求下，市场化虚拟电厂运营商不掌握电网拓扑和实时潮流信息，随着虚拟电厂聚合资源的增多，可能带来严重的电网安全隐患。基于我国电力调度体系现状，提出了虚拟机组的定义，并从虚拟机组分区聚合构建方式、虚拟电厂参与分层调控方式、虚拟电厂参与电力市场方式等方面进行阐述，提出了一套分区聚合、分层调度的市场化虚拟电厂调控架构。算例表明，所提出的调控架构能够支撑虚拟电厂运营商在不掌握拓扑信息的情况下安全且经济地参与电网调度和市场交易。

The construction of virtual power plant (VPP） is now in the ascendant. It is necessary to comprehensively consider the economic requirements of VPP operators and the safety requirements of power grid for the participation of virtual power plants in grid dispatching. However, under the current power system information security requirements, the market-oriented virtual power plant operators have no aceess to the grid topology and real-time power flow information, and it may bring serious security risks to the power grid with the increase of aggregated resources in VPPs. The definition of virtual power unit is put forward based on the current situation of power dispatching system in China. Moreover, a dispatching architecture with partition aggregation and hierarchical scheduling for market-oriented VPPs is prospected from the aspects of partitional aggregation construction method of virtual power units, multi-level scheduling mode for VPPs and way of VPPs participating in the power market. Finally, an example shows that the dispatching architecture proposed can support the VPPs to participate in power grid dispatching and market transactions safely and economically without the grid topology information.
