| Abstract: |
| The information system failure directly impacts the economic operation of the microgrid energy scheduling. In this regard, an analysis method to quantify this impact as a result of the information system failure is proposed, which positively contributes to improving the information system reliability. A model of the information system is established based on the microgrid energy control strategies. Furthermore, the energy scheduling strategy in the environment of cyber-physical system is simulated by combining the physical microgrid system topology. Subsequently, a quantitative approach to calculate the costs of both microgrids and electric vehicle users is developed. Based on this, the actual economic benefits of the microgrid considering the information system failure can be obtained. At the same time, the weak links of the information system can be effectively identified and improved by using the sensitivity analysis of the model parameters, information components and topology. |
