Abstract
With the development of informatization and intellectualization technology, the power system has become the cyber-physical power system (CPPS) with deep integration of the cyber side and the physical side. As the support system of smart grids with new forms and features, the CPPS considers the coupling relationship between the communication network and the physical power grid, and is a research hotspot in the field of smart grids. This paper provides an overview of the CPPS framework and describes the interaction between the communication network and the physical power grid. Then the mainstream modeling and simulation methods of CPPS are summarized, and the advantages and disadvantages of each method are pointed out. In the end, the paper looks forward to the possible research directions of CPPS in the future. The article provides researchers with different perspectives on the dynamic model and simulation methods of CPPS.
Highlights
With the continuous integration of computing, communication and control technologies in smart grids, the composition of power system is becoming increasingly complex, which makes the power system become the cyber-physical power system (CPPS) with deep integration of information and physics (Su et al, 2017)
Three mainstream modeling methods of CPPS are summarized: i.e., modeling based on incidence characteristic matrix, information flow-energy flow hybrid model and modeling based on theories of hybrid system
Three kinds of CPPS modeling methods are summarized: modeling based on incidence characteristic matrix, a hybrid model of information flow and energy flow, and modeling based on theories of hybrid model in the control field
Summary
With the continuous integration of computing, communication and control technologies in smart grids, the composition of power system is becoming increasingly complex, which makes the power system become the cyber-physical power system (CPPS) with deep integration of information and physics (Su et al, 2017). The research related to CPPS mainly focuses on the following directions: (1) research on the fusion modeling methods of communication network and physical power grid; (2) research on the hybrid simulation methods. The state of the physical layer changes and the new state information is transmitted to the information layer, forming a complex closed-loop system of perception – analysis – decision-making – execution In these processes, the interaction between energy flow and information flow is realized. Temperature, humidity, wind speed, light intensity and other non-electrical information that may affect the operation of equipment is needed This information will be uploaded to the control center through the power communication network, and the grid status will be updated according to the control center’s instructions. To study the impact of these problems on the physical grid, the quantitative analysis should be carried out through CPPS modeling
