Equipped with millions of sensors and smart meters in smart gird, a reliable and resilient wireless communication technology is badly needed. Mobile networks are among the major energy communication networks which contribute to global energy consumption increase rapidly. As one of core technologies of smart grid employing mobile networks, Demand Response (DR) helps improving efficiency, reliability and security for electric power grid infrastructure. Security of DR events is one of the most important issues in DR. However, the security requirements of different DR events are dynamic for variousactual demands. To address this, an event-oriented dynamic security service mechanism is proposed for DR. Three kinds of security services including security access service, security communication service and security analysis service for DR event are composited dynamically by the fine-grained sub services. An experiment prototype of the network of State Grid Corporation of China (SGCC) is established. Experiment and evaluations shows the feasibility and effectiveness of the proposed scheme in smart grid employing mobile network.
