Short Description of the Presentation

Modern grids are different than the traditional power networks in various aspects. They interconnect different types of energy sources and loads. They comprise ac and dc components and circuits. Finally, they are designed to operate independently or connected to the large power networks. The dc micro grids have attracted much attention recently due to the advances in dc components. Stability of such systems is an attractive area of research especially when nonlinear components such as constant-power loads (CPLs) exist. In this presentation, dynamic modeling, stability, and safe operation of dc network powered by solar power is introduced. The destabilizing effect of CPL is considered and an advanced adaptive control mechanism is introduced to mitigate it. Hardware tests on an interconnected dc network is presented to support theoretical conjectures.
