This chapter describes the main aspects about distributed generation (DG) systems and investigates the operation of DG systems based on static power converters connected to weak grids. Initially, the concept of DG is discussed, and the main topologies for the con‐ nection of DG systems to the grid are covered. Converters used in such applications are also introduced. When connected to weak grid...

Direct drive wave energy converters (DDWECs) have gradually become the mainstream of (WECs). In order to make better use energy, storage devices and other renewable sources are often used suppress power fluctuation in DDWECs. However, addition will increase complexity converter system number switches. Considering flexibility nine-switch (NSCs), this paper proposes a novel grid-connected/off-gri...

The increasing integration of grid-connected renewable energy systems impose major challenges reliability and power quality within grid system. Grid-connected must ensure stability, accommodate low voltage ride-through capability, comply with codes under unbalanced dips to avoid any grid-disconnection. In this context, paper proposes a novel control strategy improve inverter conditions. Positiv...
