Evaluation method for voltage fluctuation performance considering cyber soft failure
Voltage regulation based upon cyber systems has been extensively used with the development of cyber-physical systems. Still
cyber failure may result in controlling failure
which inevitably has an effect on the overall voltage performance of distribution networks. In order to access the influence of a cyber fault on voltage regulation
a cyber system validity model considering cyber soft failure is proposed. The analytical approach of voltage fluctuation and measurement indices of voltage fluctuation are also developed. Based on a simulation of a IEEE 33-bus system
the proposed model is proved to simulate the voltage regulation process taking cyber soft failure into consideration. Each influence of different fault factors is analyzed
which provides practical technical support for the planning and operation of the distribution system. This paper provides strategies for the research into cyber fault of distribution networks
which has critical significance along with follow-up value.
