多层Petri网应用于电网规划

Application of A Multi-layer Petri Net Model for Power Grid Planning

Petri网应用于电网规划时,既要考虑实际的潮流,又要考虑负荷需求信息以及电力系统运行的限制,所以 不能按照传统的方法选择一个单一的Petri网来建模。把基本Petri网和一个改进的可变弧权Petri网通过一个“界面” 结合起来模拟规划过程,这个多层的Petri网模型能够很好地协调电力系统负荷需求和电力供应能力之间的关系。

While Petri nets are used in electric power systems, different from the traditional method, a hydrid multi-layer Petri nets model is proposed to simulate the multi-layer systems. Via a communication interface the author combines a basic Petri net with an extension of continuous Petri nets called a Variable Arc Weighting Petri net (VAWPN). The model can describe the process of the power system planning.
