Abstract
The share of decentralized power generation is increasing, which causes general changes and challenges for the conventional power system. Hence, distribution system operators (DSO) need new technologies to ensure the stability of the entire electrical power system. As a feasible solution for structuring power networks, the Clustering Power System Approach (CPSA) has been introduced, providing an innovative and reasonable way of decentralisation for future-oriented power systems. With this approach, based on the Cluster Fractal Model, the stabilization of the power systems can be realized in a bottom-up direction from decentralized generation units in distribution grids to the upstream transmission grids. However, to accomplish smart operations in such decentralized and intelligent electricity networks an appropriate strategy for the interoperation between cluster areas is needed. To realize this concept this paper proposes a real-time orchestration system as a core functionality of Smart Grid Cluster Controllers (SGCC) to run the distribution control and management functions. Hereby, the characteristic needs of such functions inside or between clusters can be taken into account. Structural or hierarchical dependencies of the functions can also be considered. Lastly, the SGCC is implemented on different hardware platforms.
