With the rapid development of smart grid and energy Internet, the electric power communication network (EPCN) has more and more data traffic. Under the premise of safety and reliability, this paper studies the survivability technology for dispatching service of EPCN to improve the resource utilization rate of EPCN and increase the network capacity. We design the equipotential preconfigured cycle (<inline-formula> <tex-math notation="LaTeX">p </tex-math></inline-formula>-Cycle) algorithms based on the failure independent path-protecting p-Cycle (FIPP <inline-formula> <tex-math notation="LaTeX">p </tex-math></inline-formula>-Cycle). To guarantee the optimality of the result, we first build a mixed integer linear program model, namely, equipotential path-limited mixed integer linear program of the FIPP <inline-formula> <tex-math notation="LaTeX">p </tex-math></inline-formula>-Cycle. Then, we develop a time-efficient heuristic algorithm, namely, the heuristic algorithm for configuring <inline-formula> <tex-math notation="LaTeX">p </tex-math></inline-formula>-Cycle. As an example, we simulate with EPCN topology from the Jiangsu Province of China, considering end-to-end limited-path protection, reliability of demand, and predefined communication topology given by the electrical grid and the presence of a central dispatching center. Compared with the traditional survivability technology, the two proposed algorithms give better performance.
