Communication Requirements and Solutions for Secure Power System Operation

The further increase of the contribution of D&RES in the peak power balance up to 60 % in accordance with the goals of the European Communities for the year 2010 requires innovative approaches to keep the security of the power supply on the actual high level. The communication will be the key for the further suitable operation of the power system. New communication facilities will be necessary to provide the reliable data for e.g. decentralized energy management, integrated planning tasks and to ensure the provision of system services by D&RES. The communication network with different physical communication channels has been investigated in scope of some pilot projects. Further more, the application of communication standards is investigated and in the result the use of the data models and the services of the communication standard IEC 61850 (for substation communication) is recommended. Also the standard IEC 61968 has been discussed. Finally, it becomes clear that the implementation of more communication in the distribution level is necessary for the secure power system planning and operation.
