The decentralized generation and storage offers new opportunities for a reliable structure of the electrical power grid. It is proposed to subdivide the power grid into much smaller cells than in a traditional power grid. Since all of these cells contain distributed generators, they could be able to operate on their own, if necessary. In case of a global black-out, the individual cells could be able to survive. The paper discusses the size of such cells. In the next part, technical issues are discussed. In each cell the balance of power generation and demand must be maintained. Furthermore, a suitable grid control like virtual inertia must be applied to all related inverters. This requires an intelligent control not only of the generators but also of selected loads, which need to be reduced or shut down in case of lack of energy. Solving these issues for an individual cell leads to a bottom-up approach to operate a complete global power grid with fluctuating, decentralized renewable energies.
