Network Security Management (NSM) focused on Dispersed Generation

Progress in the use and the structure of primary energy resources requires modifications in the structure of generation and operation of the power system in the future to fulfill high requirements of secure delivery of electrical energy. The power system is one of the critical infrastructures of industrial countries and requires special consideration. This paper discusses topics on how power system can be operated securely with such a large share of mostly not dispatched power sources. It presents issues on how the reserve power can be limited which is required for compensation of power fluctuations and ensuring safe network operation. In this context, a vision sees the power system of the future consisting of a number of self-balancing distribution network areas. In each of these areas a significant share of the power demand will be covered by renewable and CHP generation.
