The paper proposes a Fully Flexible Power Transmission & Distribution System (FPTDS) for the next generation power grid, the FPTDS structure used the brand new flexible electric equipment: Energy-Router, Energy-Switcher and Energy-Hub. And then from the Cyber Physical Systems(CPS), the paper gives a Power-CPS (P-CPS) interconnect reference model, and thereby, focuses on designing the fully flexible next generation equipment for Fully Flexible Power Distribution System (FPDS): Energy-Switcher architecture in detail, and researches the next generation distribution grid patterns with Energy-Switchers, presents the grid patterns for all kinds of practical application scenes, finally simulates the Energy-Switcher AC & DC power supply pattern under computer condition, the simulation results demonstrate the systems are feasible and valid.
