Flexible resource adjustable interval construction method based on virtual power plant

The invention discloses a flexible resource adjustable interval construction method based on a virtual power plant. The method comprises the following steps: firstly, establishing a branch thermal stability safety domain model in an active power output space of a generator node taking a virtual power plant node as a key node; then, taking active power injection as a coordinate axis, and establishing a multi-dimensional thermal stability security domain analysis model and a rapid solving method thereof in a key node space; in consideration of application requirements of actual engineering, a multi-dimensional security domain display model represented by a two-dimensional plane combination graph is researched. 本发明公开了基于虚拟电厂的灵活性资源可调区间构建方法，首先建立了以虚拟电厂节点为关键节点的发电机节点有功输出空间下的支路热稳定安全域模型；然后，以有功功率注入为坐标轴，建立了多维热稳定安全域分析模型及其在关键节点空间的快速求解方法；考虑到实际工程的应用需求，研究了二维平面组合图形表示的多维安全域显示模型。
