针对具有恒定功率负载的分布式电力系统，提出了面向设计的准则，以保证在大扰动下的稳定性。该标准对输入滤波器参数施加了设计约束，例如Q因数，并对系统可以支持的“理想”恒定功率负荷量施加约束。这些判据基于李亚普诺夫稳定性理论、混合势函数和平衡点的存在。通过计算机仿真对解析判据进行了验证。
Design oriented criteria are developed for distributed power systems with constant power loads to guarantee stability during large disturbances. The criteria place design constraints on the input filter parameters, such as the Q factor, and constraints on the amount of "ideal" constant power load that a system can support. The criteria are based on Lyapunov stability theory, mixed potential functions, and the existence of equilibrium points. The analytical criteria are validated by means of computer simulations.>
