“…According to Equation (5), the expected loss of load from the power grid is the sum of the expected losses of all CEs in the entire communication network, ultimately leading to a decrease in the expected loss of load G in the third stage of the game. Moreover, according to Equation (11), as γ increases, the speed at which p ij decreases gradually slows down, resulting in the same slowing down of G ij .Therefore, with the increase in the total number of defense resources γ, the expected loss of load G in the third stage of the game is gradually reduced, and the decrease in speed gradually reduces.…”

“…After all defense resources have been allocated, the defense resources of each CE in the network remain unchanged or increase compared to the situation where the total number of defense resources γ is small. According to Equation (11), the more defense resources CE(i, j) is allocated, the lower the probability p ij of being attacked by a failure. Therefore, as the total amount of defense resources γ increases, the probability of each CE in the network being attacked and malfunctioning remains unchanged or decreases.…”

“…There have been numerous publications on the performance indicators of regulation methods and strategies for the study of CPPS cascading failures and system regulation mechanisms [7][8][9]. To maintain the power balance and stability of the power system, disconnecting a portion of the load from the grid is called load shedding.The load shedding operation of the power grid is an important means to ensure the safe and stable operation of the power grid [10,11], and the value of the load power change caused by the load shedding operation is called the load shedding amount.…”

With the development of power technology and communication technology, the power grid and power communication network have become interdependent and closely coupled. The load shedding operation of the power grid is an important means to reduce the occurrence of chain faults and ensure the safe and stable operation of the power grid. Based on the transmission of load control services in the communication network, this paper establishes a model for a dual-network coupled cyber physical power system (CPPS). Considering communication edge faults, the associated load capacity of the communication edge and the expected load loss of the power grid are defined. On this basis, the paper proposes a complete information zero-sum game mechanism called “defense attack defense” for communication edge failures, which takes the expected loss of load from the power grid as the benefit. The paper studies the optimal attack and defense game strategies and provides the algorithm implementation process for the three stages of the game. Considering the bandwidth capacity of the communication edge, this paper uses the Dijkstra algorithm or k shortest paths (KSP) algorithm with the cost factor of the communication edge as the weight to plan the main and backup communication channels for multiple load control services. The simulation results show that the game mechanism proposed in this paper can effectively reduce the expected load loss from the power grid and improve the stability of the CPPS.
